New technology has been required to achieve compliance with Tier 4 standards, resulting in drastic changes to the fuel injection systems of diesel engines and posing new challenges for equipment owners and operators.
These changes make engine components far less tolerant of liquid and particulate contamination. For optimal engine performance in line with stricter emission standards, high quality fuel filtration is critical at all stages, from storage to consumption.
The use of ultralow sulfur fuel and biodiesel blends allow for higher amounts of water in fuel, and water contamination causes a variety of problems for diesel-powered engines:
Microbial growth. Commonly referred to as ‘diesel bug,’ these microorganisms thrive in water-contaminated fuel. In large quantities, they cause a variety of issues including blocked filters, reduced fuel efficiency, increased emissions, and even total engine failure. Once a case of diesel bug becomes moderate to severe, expensive remediation is required to control the contamination.
Engine component degradation. Water contamination in fuel reduces lubricity and encourages acid buildup, leading to component wear and corrosion.
Reduced fuel quality. Along with acidity and sediments forming as fuels degrade (oxidize), the cetane number can fall. The cetane number measures the quality and performance of diesel fuel, so a lower number results in increased emissions and reduced efficiency.
As engine technology evolves, high fuel quality is paramount, and filtration technology must keep pace. On-board filtration can’t bear all the weight of contaminated fuel, so maximizing filtration in the storage, transfer, and dispensing stages is invaluable for mitigating equipment problems and high repair costs.
GHCF: A Superior Fuel Filtration Solution
Schroeder Industries is meeting the challenges of changing engine technology and emission standards with innovative fuel filtration solutions. The GHCF, or GeoSeal® High-Flow Coalescing Filter, is a compact and versatile filter engineered for exceptional particulate and water filtration during transfer and delivery, polishing, and dispensing.
Here’s what makes the GHCF an ideal choice for a variety of fuel applications:
Compact design and footprint. Conventional fuel filtration setups often utilize several individual filters to achieve the levels of filtration that just one GHCF offers. With a GHCF, the size and weight of the filtration setup are reduced. Additionally, a GHCF costs up to 50% less than conventional multiple-filters setups.
Exceptional flow rate for its size. The GHCF’s 25gpm flow rate is very high for its relatively small footprint, allowing efficient bulk filtration in a compact package.
Easier element changeouts. Unlike most comparable fuel filters on the market, which require full element length clearance, the GHCF only requires 4.5″ of clearance. This reduced clearance requirement makes it ideal for installations with limited space such as polishing panels and cabinets.
Lightweight and corrosion-resistant. The all-aluminum construction with anodization results in a lighter and corrosion-resistant filter compatible with diesel and biodiesel.
Compatible with both pressure and vacuum applications due to its unique inside-to-outside flow design.
Superior filtration. The GHCF and and its coalescing filter elements are engineered for excellence in particulate and water filtration, and with GeoSeal® Quality Protection, only high quality filter elements can be utilized.
The GHCF comes equipped with a large, sump-level sight glass allowing water levels in the sump to be determined at a glance. Other options including automatic water drain functionality, water in fuel sensors, and sump heaters can be easily retrofitted to the filter. The GHCF makes an excellent substitute for high flow cartridge and spin on absorbing or coalescing solutions.

Every hydraulic system is subject to contamination from a variety of sources, including air (or gaseous) contamination. If air contamination builds up in your hydraulic system, you can expect the following:
Gaseous cavitation. As air bubbles coalesce, grow, and collapse inside a hydraulic system, it causes loud noises and can potentially damage the internal hydraulic components.
Spongy hydraulics. Unlike hydraulic fluid, air is compressible. As a result, too much air contamination can cause a delayed response, or ‘spongy’ feeling in a hydraulic system instead of an instant reaction. The result is inefficient, unpredictable, potentially dangerous system performance.
Oxidation of hydraulic fluid. When oxygen reacts with hydraulic fluid, it produces varnish, a sludgy byproduct. This varnish increases fluid viscosity and can build up around valves, causing sluggish performance, damage to system components, blocked return lines and more.
Between safety issues, poor performance, and costly repairs, addressing this contamination is vital for safe and efficient hydraulic operations. Air contamination can be addressed by a specialized in-tank air filter, but not every hydraulic air filter is created equally. Enter, Air Fusion Technology by Schroeder Industries.
Air Fusion Technology: Superior Hydraulic Air Filtration
100 psi (7 bar), 40 gpm (151 l/min)
Air Fusion Technology, also known as the AFT, is Schroeder’s new in-tank air filtration solution. The AFT is engineered to increase machine reliability and efficiency, protect components, and even allow for a downsized hydraulic reservoir!
When compared to a standard out-to-in flow in-tank filter, the AFT reduced the amount of air which entered the suction line on the first pass by 20%. As the AFT decreases fluid turbidity, it channels fluid upwards and promotes rapid bubble coalescence. These bubbles quickly rise to the surface of the reservoir and dissipate.
By contrast, the traditional filter was less effective at reducing turbidity. This allowed air bubbles to stay suspended lower in the reservoir and enter the suction strainer.
What makes the AFT more effective than other hydraulic filters?
The AFT’s exceptional effectiveness is due to its thoughtfully engineered design. Let’s break down the key design aspects of this revolutionary filter:
The unique filter head design swivels independently of the inlet port, allowing toolless element change-outs.
A specialized bypass valve in the head of the filter allows the filter to de-aerate fluid even when in bypass for greater filtration efficiency.
The patented endcap design allows bypass flow to enter the top of the element while still being subjected to the diffuser shroud. This helps maximize filtration.
Schroeder’s patented Lock & Key Quality Protection element design ensures only high-quality Schroeder elements are being used. To ensure that the AFT performs at its full potential, it’s important to use only high-quality filter elements.
The de-aeration diffuser shroud significantly reduces fluid turbidity. Less turbulent fluid allows for faster bubble coalescence and improved air filtration.
The internal flow distribution cone redirects fluid towards the top of the reservoir, allowing air to exit the hydraulic fluid more easily.
Improve system efficiency and even downsize your reservoir!
Energy efficiency is a major component of Schroeder’s Energy Sustainability Initiative. With the AFT, our goal is to create a smaller, more efficient hydraulic system to help our customers get the most out of their fuel source, whether it’s diesel, hydrogen, or electricity.
The AFT is so effective and efficient in its filtration capabilities that it’s possible to downsize a machine’s hydraulic reservoir by up to 60%!
A smaller reservoir results in a lighter system, which can improve energy efficiency. With less room taken up by the hydraulic tank, space also becomes available for a larger fuel tank, additional batteries, or other useful components.
Air Fusion Technology will help you get the most out of your hydraulic reservoir! If you are interested in improving air filtration in your hydraulic applications, please request a quote.
Clean, dry hydraulic fluid is critical for optimal machine performance and protecting system components. Oil dehydration systems are specialized hydraulic filtration systems designed to remove free water and dissolved water from hydraulic fluid.
The Dangers of Liquid Contamination
Contamination of all kinds is responsible for the majority of hydraulic machine failures. Liquid contamination, such as water, will oxidize inside the system and cause corrosion of metallic components. Not only does this damage critical parts of the hydraulic system, but tiny free-floating solid contaminates caused by the corrosion will continue to wear down the system and compound the damage further.
Water contamination can come from a variety of sources. Here are just a few:
Leaking cooler/heater and pipe work
Filling with new contaminated oil
Leaking hydraulic component seals
Tank breathing (if desiccant breathers are absent or applied incorrectly)
Pressurized water cleaning
Oil Dehydration Solutions from Schroeder Industries
In the industrial manufacturing world, preventing liquid contamination is essential. To thoroughly accomplish water removal in a system, we use either positive pressure or vacuum units.
At Schroeder Industries, we have four (4) machines engineered specifically for oil dehydration:
The Triton Dehydration Station® uses patented mass transfer dewatering technology to eliminate 100% of free water and up to 90% of dissolved water. Ambient air is conditioned to increase its water holding capability before injecting to the reaction chamber. Fluid is equally distributed and cascaded down through reticulated media and the conditioned air stream. Water is transformed to water vapor and is expelled from the unit as moist air/stream.
The relative humidity of the incoming fluid is continually monitored by an integral AS1000 and displayed real-time on the control panel. Also includes a 2.4kW heater option for unheated reservoirs.
The North American Vacuum Dehydrator (NAV) uses vacuum dehydrating technology to remove both free and dissolved water, and gases, from oil. In addition to water and gas, the NAV also removes solid contaminants from the oil with the use of highly efficient filter elements installed on the unit. The NAV is designed for use with larger applications, such as the conditioning of oil in larger hydraulic and lube reservoirs.
The Schroeder Vacuum dehydrator SVD01 designed for dewatering, degassing and filtering hydraulic and lubrication fluids. It operates on the principle of vacuum dewatering to eliminate free and dissolved water as well as free and dissolved gases.
By using Schroeder Dimicron filter technology, which has a high contamination retention capacity and filtration efficiency, the SVD01 is extremely cost effective. Perfect for service work thanks to its compact and mobile design.
Positive Pressure and Vacuum Dehydration, How Do They Work?
There are many hydraulic oil machines that only remove free water. All of Schroeder’s Dehydrating Units remove both free water and entrapped/dissolved water from the oil.
Our vacuum options can also remove dissolved gases.
Positive pressure is when ambient air is conditioned through our patented process to increase water holding capabilities before being introduced to a reaction chamber.
In the reaction chamber, the wet oil meets conditioned air (air conditioned by an external hydraulic filter) and the water transfers to the air.
The water vapor is then expelled from the unit with the air as a moist air stream. Dry oil is then returned back to the system.
This positive pressure dehydration technology is found in our Triton Dehydration Station® Series.
Vacuum dehydrator for oil removes free and dissolved water and gases. This includes any other particle that could affect your oil.
Our vacuum technology uses ambient air, combined with reduced vapor pressure in the reaction chamber, to effectively remove the water and gases from the oil. The water and gases are condensed and collected for disposal while the dry oil is returned to the system.
What Industries Can Oil Dehydrators Be Applied To?
Turbine bearing lubricants
Electro-hydraulic control system (EHC) fluid
Boiler feed pumps lubricant
Pulp & Paper
Press and dryer section cylinder bearing lubricant
Hand-held filtration systems are compact, self-contained, “light-viscosity”, industrial separation systems.
With over 70% of all premature system failures being attributed to hydraulic and water source contamination, it is critical to implement the finest portable oil filter machine to all phases of a hydraulic circuit. That includes the flushing, transferring, and filling processes. The flexibility of portable filtration makes addressing filtration across these different phases easy.
Filter carts are are a convenient mobile alternative to stationary units, but hand-held units take this a step further. Portable filter units utilize the same filtration technologies most commonly found in full-size filtration cart systems, but offered in a portable size, similar to a Black & Decker Hand Vacuum. Often times, at least in our case, these units are sold with high efficiency, high capacity liquid pressure filter elements capable of removing particulate contamination and/or water quickly, conveniently and economically from the hydraulic fluid.
Hand-held filter elements are especially critical to the operating system pressure lines since new fluids often have contamination levels significantly higher than the recommended amount in most hydraulic systems. These units are small enough for use as drum or tank top filtration for cleaning up existing systems as well as the pre-filtration of new fluids.
Why Schroeder Industries?
As the markets that uses hydraulic components become more dynamic, they are now more dependent on the highest quality filtration, separation, and reservoir accessories available.
Our hand-held systems are the premier offline, portable filtration systems for maintaining oil water separation and mineral-based fluid conditioning in the market.
Which Schroeder Industries portable filtration unit is right for your needs?
With two (2) product offerings available, each with a proven track-record, our solutions are the industry go-to for affordable and easy-to-use filtration:
Schroeder’s Handy Filter System Basic Cart is a compact, self-contained “light-duty” filtration system equipped with high efficiency, high capacity elements capable of removing particulate contamination and/or water quickly, conveniently and economically. It is perfect for cleaning up existing systems as well as for pre-filtering new fluids, since new fluids often have contamination levels significantly higher than that recommended for most hydraulic systems.
This portable filtration system’s compact, lightweight design with replaceable element cartridge and reusable bowl minimizes landfill waste. Element service is easily accomplished through the top-ported filter housings. The optional dual filter assembly allows for water and particulate removal or staged particulate contamination removal.

In addition to an in-line hydraulic filtration strategy, an offline filter system can greatly enhance the cleanliness of hydraulic fluid. A Filter Cart System is a stand-alone unit that operates independent of the main hydraulic system, allowing it to function even when the machine is turned off.
Often referred to as an offline filtration or kidney loop systems, Filter Cart Systems have many application points within a plant or factory:
Filtering incoming hydraulic fluids prior to adding to bulk storage
Filtering new fluid before it is put into service
Fluid transfer and filtering before adding to a hydraulic reservoir
Supplementing current hydraulic filtration already in the system
Roll-off cleanliness – cleaning a reservoir on a piece of equipment prior to shipment to ensure peak fluid condition
Cleaning up a hydraulic system following component replacement
Whether your machine is new or many years old, the cleaner the hydraulic fluid, the better the operating condition. In hydraulic systems, 70 to 90% of wear and failure is contamination related. Issues such as defects, misuse or age can be traced to only 10 to 30% percent of failures.
While clean fluid is critical to proper system operation, unfortunately, contamination cannot be stopped. However, with Schroeder Industries technology, it can be managed!
Schroeder Industries Filter Cart Systems
Schroeder Industries offers up to 10 different types of Filter Cart Systems. All of these carts offer the convenience of mobile use. The mobility allows for easy portability and requires less storage space.
Our filter carts are equipped with high efficiency filter elements to remove solid particulates and/or free water quickly and efficiently. The onboard filtration systems are available in either single (one filter) or staged filtration (two filter) configurations.
Our systems range from simple filtration carts (hose to reservoir, powered on, processed through a filter) to our SMART® carts (diagnostic and SMART® controlled components in addition to the standard filter cart process mentioned above). These include contamination monitoring units such as our CS1220, AS1008 and sensor interfaces for data logging and data transfer.
Various flow rates are available depending on model code selected. Kidney loop systems can also be designed for a particular application.

Kidney loop systems clean hydraulic fluid and prolong the life of the fluid, filters and equipment. These external filtration systems draw hydraulic fluid directly from the reservoir into a short filtration circuit, then return the cleaned fluid to the reservoir. A kidney loop system can be used to supplement in-line filters when the in-line filter does not provide adequate turnover.
Schroeder’s Kidney Loop System is an off-line stationary version of the kidney loop filter systems on portable carts. It is a compact, self-contained filtration system equipped with high efficiency, high-capacity elements capable of removing particulate contamination and/or water contamination quickly, conveniently and economically.
Keeping Hydraulic Fluid Clean
In a system where only one filter is used, this one filter must remove all of the dirt generated in the system.
By using both pressure and return filters in the system, the work load is shared, making it easier to maintain the recommended fluid cleanliness level for the hydraulic system. However, the reservoir might still contain contamination accumulated over time and from the environment.
An off-line kidney loop system can be added to remove solid particles, improve reservoir cleanliness, and extend the life of the system’s filter elements.
In hydraulic systems, 70 to 90% of wear and failure is contamination related! Only 10 to 30% can be traced back to misuse, defects or age. Contamination cannot be stopped, only slowed down.
System efficiency can drop by up to 20% before an operator even detects a problem. This can appear as cylinder drift, jerky steering, erratic operation or slower performance. Overall, contamination results in shorter service intervals, higher operating costs and lost productivity.
A major portion of particulate contamination can be effectively and efficiently removed by using our kidney loop systems. Reduced downtime, fewer repairs, and more efficient operation can save a company production costs in the future.
Schroeder Industries offers several different types of stationary kidney loop systems, including versions with pneumatic motors in place of standard electric motors. The pneumatic motor offers the same flow capability using the same components, but without the need for an electrical outlet. The greater portability allows for field options on service trucks.
Watch to learn more about Schroeder Industries’ Kidney Loop filtration offerings and how they can benefit your hydraulic systems!
Kidney Loop Filtration Systems vs. In-Line Filtration Systems
A kidney loop system is a fully independent filtration unit, containing its own motor, pump, and filter. The kidney loop system can be linked directly to a reservoir and run intermittently as required, or continuously. Since they function independently from the machine’s hydraulic system, kidney loops are more efficient at removing contamination from fluid and retaining any captured dirt within the filter.
Typical in-line filtration systems only run when the hydraulic machinery is active. The key benefit of a kidney loop system is that it can run 24/7 and polish the hydraulic fluid even when the machinery is powered down.
Supplementing in-line filtration by system filters when adequate turnover cannot be attained
Large volume systems requiring multiple filters in different locations
Cleaning up a hydraulic system following component replacement
Problem: A customer was experiencing problems with external ingression of coal dust getting into the 255 gallon (965 L) lube oil reservoirs on their coal pulverizers. This caused degradation wear on the bearings and bull gears, which lead to premature aging of the system components.
Solution: The installation of KLD filtration skid cleaned up the system fluid from coal dust particulates and other contamination. As a result, the internal wear on system components as well as unscheduled downtime due to contamination was reduced dramatically.
Watch to learn more about Schroeder’s Kidney Loop product extensions:
Keeping a hydraulic system free of contamination is critical for system efficiency and longevity, and high quality filtration elements are the key to contamination control. Unfortunately, it’s not uncommon for customers to seek out low-cost, off-brand imitations of Schroeder Industries filter elements in order to cut down on expense.
Not all filter elements are created equally, and just because a given element fits in a Schroeder filter housing, it doesn’t necessarily provide adequate filtration. Cut-rate imitations may claim that “All filtration elements are guaranteed to meet or surpass all specifications of the original equipment manufacturer” but that’s not always the case. Take a look at the numbers below and see for yourself:
# of pleats
Pleat Height (in)
# of pleats
Pleat Height (in)
Cheaper knockoff filter elements trade functionality for lower cost, exposing the hydraulic system to increased risk of contamination, machine downtime, and system failure. Furthermore, the blame for these failures may be wrongly placed on the housing manufacturer, not the cut-rate filter element.
How can we ensure that proper, high-quality filtration elements are being used?
Quality Protection: Guaranteeing High Quality Filter Elements, Every Time
Quality Protection is Schroeder’s answer to the problem of mismatched, inadequate elements. The patented, premium Quality Protection elements are engineered specifically for superior performance when paired with Schroeder filter housings.

OEM’s will capture aftermarket revenue from Quality Protection elements; exponential growth year after year
Increase in machine productivity and reliability when Quality Protection filtration elements are deployed
Overall reduction in warranty claims when hydraulic equipment is protected by superior filtration
Why Do My End Users Need Quality Protection?
Hydraulic system downtime and repairs represent a significant portion of overall costs to equipment end users. Contamination is the leading cause of hydraulic machine downtime, accounting for as much as 70% of premature machine failures. Ensuring the highest quality filtration protects your end users’ equipment from contamination-related failures and associated costs.
How Does Quality Protection Benefit My Business?
Quality Protection is the clear choice for protecting your end user’s hydraulic equipment from contamination-related damage, but how does it benefit your business directly?
Not only will your equipment perform at like-new levels, but Quality Protection can also provide an increase in aftermarket retention year over year. By taking advantage of our Quality Protection filter elements with the private labeling option, you may see up to 90-100% aftermarket retention. Compare this to the expected retention when using standard Schroeder elements with or without private labeling.
Over a 10 year period, one may sell an estimated triple the quantity of filter elements when implementing a Quality Protection strategy than without. The associated boost to sales margins makes this a highly profitable, winning strategy.

Contamination cannot be completely stopped, but proper fluid filtration can prolong the lifespan of your hydraulic components—and a successful treatment strategy begins with accurate diagnostics.
Portable Fluid Condition Monitoring
To make fluid assessments more convenient, Schroeder Industries developed several portable fluid condition monitoring systems. These compact units are designed to deliver real-time insights into the health of a variety of hydraulic fluid types. On-site analysis with a portable condition monitoring unit saves time and money compared to shipping samples to oil testing labs, or using complicated analysis kits. Their portability makes them usable in the field, in remote locations, along a manufacturing process production line—anywhere a hydraulic system can be found.
Introducing Total Fluid Condition (TFC)
The new TFC unit represents the latest in fluid condition monitoring technology. This revolutionary portable service unit is designed to measure and differentiate particulate contamination, as well as relative water content and temperature.
Improving Contamination Data Accuracy
Correctly identifying the type and source of hydraulic fluid contamination is critical for developing a treatment strategy. The TFC unit improves upon the accuracy of fluid contamination data in synthetic and mineral oil based hydraulic fluids, offering users a more complete analysis of their fluid health than was previously possible. This improved precision stems from the new direct digital imaging sensors incorporated into the TFC units.
Other portable fluid contamination monitoring units have utilized light-based sensors, which struggle to differentiate between contamination types, but direct digital imaging sensors can distinguish air bubbles and water molecules from solid particles. This results in a more accurate ISO count, and better understanding of the fluid’s health.
The TFC can also sort particles into fatigue, cutting, sliding wear, and fiber categories to estimate cause of contamination. The direct imaging particle counting software coded into the unit uses size and shape-recognition technology, based on advanced algorithms, as a dirt classifier to distinguish contaminates.
Like Schroeder’s other portable fluid diagnostics systems, TFC is a powerful, versatile tool for any fluid cleanliness testing scenario:
Perfect for in-plant/industrial applications, during the assembly process or at the end of the production line.
The compact design and onboard battery also make the TFC ideal for mobile applications, such as testing for service trucks or in remote locations.
Other Benefits of Fluid Condition Monitoring
The oil waste reduction aided by the TFC unit’s fluid diagnostic capabilities doesn’t just help protect your equipment. It also reduces costs and environmental impacts related to oil waste.
All hydraulic fluid must be changed eventually, but routinely testing fluid cleanliness and addressing contamination prolongs its lifespan. This results in less frequent oil disposal, saving on the expense of new oil.
Additionally, the reduction in hydraulic oil waste and consumption helps lower an operation’s carbon footprint and environmental impact. The TFC unit is part of Schroeder Industries’ Energy Sustainability Initiative supporting carbon reduction goals across various industries, thanks to the benefits it imparts by helping extend the life of oil and reduce waste.

In recent years, the mobile hydraulics industry has been revolutionized by the development and proliferation of electric hydraulic systems. Among other inherent benefits, electric hydraulic systems could also be dramatically more energy efficient compared to traditional hydraulic systems.
How is this possible? Unlike traditional hydraulic systems, electric hydraulic motor-pump units only operate when flow and pressure are required to perform the working task at hand.
When there is no flow or pressure required, the electric hydraulic motor-pump unit switches to zero energy-mode, saving the consumption of energy and increasing the system’s efficiency. This is what we call energy efficiency.
Energy Efficiency through Electric Hydraulics
Energy efficiency, put simply, is when less energy is needed for a system to get the job done. This can be achieved by lowering the amount of energy consumed to accomplish an equivalent output (e.g. halt of use when not in operation).
Think about some of the newer car models in the market today.
Some higher-end models shut down every time the car stops at a stop light. Since the car is in idle at that stop light, why would the car continue to place tension and wear the performing components when they’re not performing their sole duty: driving?
This way of thinking is slowly creeping into hydraulics too. Experts are now looking at ways to incorporate these (and other) types of electric energy to power hydraulic machines. This is called electric hydraulics.
Electric Hydraulic Advantages
Electric hydraulic systems have some major advantages over their traditional hydraulic counterparts. The key advantages of electro-hydraulic motor pump units are:
Up to 70% more efficient than standard hydraulic counterparts
CO2 reduction = less fluid being used in the system
Component lifespan increased, especially with bearings and seals
Ability to control direction & amount of hydraulic flow by controlling direction/speed of the electric motor.
Injection molding machine systems eliminate the need for directional and proportional valves in the motion axis.
Fewer, less complicated components also simplifies troubleshooting.
Quieter run times, reducing noise decibel readings
Save space and reduce weight with lighter, more compact electric systems
Integrated electrohydraulic packages are now available. These packages include an electric motor, controller, and hydraulic pump combined into one compact unit to lower total cost of ownership.
With the rising trend of electric drive vehicles and utilizing efficient energy throughputs, there is now a need to reduce power consumption and extend the battery life through increased hydraulic efficiency. How do we capitalize on saving energy and becoming more efficient in electric hydraulic systems?
The answer: minimize the pressure drop
Electric Drive Savings Through Pressure Drop Reduction
All energy has a price, and wasting it means wasting meaningful dollars. It is desirable to have as much energy that is inputted into a system available to do useful work. In hydraulic systems, we tend to look at differential pressure across the entire system. Differential Pressure describes the loss of energy available in a hydraulic system—however, the energy is not lost, but converted into thermal energy, which is unavailable to perform useful work.
For example, a small pressure drop effects high horsepower systems, as the pump/motor group must make up for that loss of energy and operate much harder, costing more money and shortening component life. Take a look at the figure below to see an example of how much money can be saved by lowering the pressure drop by a few psi:
So how do we lower the overall pressure drop in an electric hydraulic system? That is where Schroeder’s Electric Drive media can help.
Schroeder’s Electric Drive Media
The use of Schroeder’s GREEN, Electric Drive (E-Drive) Media filtration technology guarantees safe and reliable equipment operation, all-while conserving the use of energy.
Part of Schroeder’s Energy Saver initiative, filter elements made using the all-new E-Drive Media are characterized by a low pressure drop, making them suitable for low energy requirements compared to conventional hydraulic elements under the same ambient conditions.
In certain applications, the E-Drive Media can lower the pressure drop to a point where consumers may be able to size down their horsepower requirements on their current motor and save even more overall!
E-Drive filter elements are made using an all-new specialty formulated, high efficiency, low differential pressure media and are the perfect choice for use in electric hydraulic drive motor-pump units. Use them for conserving energy bills and wherever high viscosity fluids are employed – especially at low temperatures that produce a cold start behavior.
Let’s see how our 10-micron Electric Drive media element compares to the typical synthetic microglass media available on the market today.
Technical Specs (evaluated in K-sized element):
Pressure Drop Factor [psid/gpm]
E-Drive Media (10 µ)
Typical Synthetic Media (10 µ)
Element Collapse Rating: 145 psid (10 bar)
Temperature Range: -22°F to 212°F (-30°C to 100°C)
Flow Direction: Outside to Inside
E-Drive Media is currently rated for 10-micron filtration, with other micron options available in the near future.

To put it simply, the most important thing we can do, is make sure your fuel is free of any contaminants. This can include water, particulates, fungi, etc. Our products are designed to remove these contaminants.
Contamination can cause microbial growth, which can cause destruction in your fuel systems. This can lead to field failure and can allow bacteria to spread in your system.
Fortunately, with Schroeder Industries, our filters can get these destructive contaminants out of your fuel. Bringing them up to exceptional cleanliness levels.
With our fuel diagnostic technology, you can take a preventative approach and know when exactly your fuel may need extra support.
Our Fuel Filtration Technology and the Environment
We recognize the world is seeking more environmentally sound ways of creating equipment that uses more efficient technologies and systems.
We are always looking for ways to keep this global movement in the focus of our development. This includes making strides in creating more energy efficient fuel filtration technology.
Many of the global equipment manufacturers are making advancements in the electrification of mechanical or hydraulic systems and equipment. This doesn’t get rid of the need for diesel fuel or alternative fuels, but underscores the importance of better fuel filtration.
Modern fuels are made to adhere to the standards addressing emissions, equipment reliability, safety, and storage. Therefore, our fuel filtration technology follows the same standards. It is of high importance for us to know the problems faced as fuels continue to change.
Engines are becoming smaller to make room for the electrical components, wiring, and storage. It is crucial to provide the highest performance filtration in a compact and lightweight package.
However, this does not eliminate the need for bulk diesel, or alternative fuel. This makes the need for your pristine fuel quality even more essential.
Schroeder Industries also understands the importance of being environmentally friendly.
We use advanced technologies to minimize the energy needed to clean and condition fuel. This encourages the reclamation of fuels that would normally be disposed of. Doing this can result in reduced waste and an overall reduction in emissions, helping to accomplish a cleaner world.
Schroeder Industries is ISO 9001 certified and members in good standing with PEI. Both organizations help fulfill our dedication to making sure all of our customer’s fuel quality is outstanding.
