AutoFilt® RF9: Superior Process Filtration for Hydroforming

Header graphic with text reading: Superior Filtration for Hydroforming. How can your business benefit from the AutoFilt® RF9? Ask the Experts.

What is hydroforming?

Hydroforming is a specialized deep draw manufacturing process used to create a wide variety of metal components and is especially popular within the automotive industry.

In the sheet hydroforming process, highly pressurized water is applied into a mold, and the water pressure forces the metal to conform to the shape of the die.

Diagram showing the hydroforming process.

Compared to conventional stamping methods, hydroformed parts can be created in more complex shapes with greater efficiency, thinner metal sheets, and high-quality surface finish.

Why is process filtration so important for hydroforming applications?

Like any process water application, contamination can greatly affect the lifespan and performance of the high-pressure hydroforming press.

To protect vital downstream components like high pressure pumps and manifolds from wear and tear, high-quality process filtration is a must for any hydroforming system. If left unchecked, contamination can wear out machine components, reducing operational efficiency and forcing expensive repairs and costly downtime. Additionally, defective/scrap material output can increase.

The process filtration experts at Schroeder Industries understand the impact that high-quality filtration has on a business. We can find a Schroeder solution for virtually any process filtration application, including hydroforming:

Every Successful Filtration Plan Starts With Superior Oil Analysis

Clean Oil is the Key to Productivity

Is your hydraulic equipment experiencing more downtime than usual? Are you noticing that your equipment is operating less efficiently?

If your operation is paying a price for the inconsistent performance of your vital equipment, high contamination is most likely to blame.

Hydraulic fluid contamination from a variety of sources is by far the most common cause of system inefficiency and failures. In fact, approximately 80% of all hydraulic equipment failures can be directly attributed to the effects of fluid contamination!

Consistently clean hydraulic oil is vital to every operation that relies on hydraulic equipment. Additionally, systems that rely on process water or run on diesel fuel are also vulnerable to the effects of contamination. Proactive measures to analyze fluid and prevent contamination provide significant benefits to cost and productivity:

  • Prevent costly equipment failures and downtime before they happen by detecting and treating contaminated fluid.
  • Save money on repairs by protecting system components from contamination and extending their lifespan.
  • Get the most out of your hydraulic oil by detecting and treating contamination before the oil’s life is exhausted. As oil prices continue to rise and hydraulic oil supply lines remain unstable, it’s important to conserve the oil you have!
  • Increase fuel efficiency not just by filtering your fuel source, but by improving overall system efficiency when you reduce contamination-related wear. Clean fuel and efficient operation reduces fuel consumption, cuts carbon emissions, and saves your operation money.

Save Oil Through Filtration and Reduce Your Carbon Footprint

An operation’s carbon footprint is influenced by many factors, and making a business more sustainable requires a combination of solutions. One often overlooked way to increase sustainability is through optimal oil filtration.

All hydraulic oil, turbine oil, and other lubricants have a lifespan, as contamination and the breakdown of chemical compounds degrade oil over time. If contamination is left unchecked, oil reaches the end of its usability much faster.

Waste oil is challenging to dispose of properly, and high oil turnover increases demand for the very energy-intensive production of new oil. Much of the hydraulic oil and engine oil in use today is disposed of before its usable life is up.

Every gallon of oil that is conserved by extending the lifespan of existing oil directly contributes to a reduced carbon footprint. So, how do you get the most out of your oil?

Utilizing offline filter systems and high-quality filter elements is proven to extend the lifespan of oil significantly by removing contaminants and slowing the degradation of the oil.

Check out the following case studies where Schroeder Industries products saved a significant amount of oil or extended its service life:

Offline Filter System Saves Manufacturer 2,600+ Gallons of Oil Per Year

A plastic parts manufacturer in the automotive industry experienced frequent failures and downtime in their 16 injection molding machines. Like the majority of hydraulic system failures, high contamination load was identified as the cause. Without a quality control program for the machine oil, the customer changed oil frequently before its usable life was up.

Schroeder Industries stepped in, providing the customer a customized offline filtration system designed to tackle the high contamination:

Contamination-Related Downtime Reduced 54%

2,600+ Gallons of Oil Saved Per Year

$616,916 Cost Savings Per Year

Specialized Anti-Static Filter Elements Increase Oil Life by 3 Years at Paper Mill

When a paper mill was experiencing a shortened filter element life of just 30 days, Schroeder Industries stepped in to extend the filter life, reduce oil waste, and reduce unscheduled downtime.

An expert investigation revealed the culprit affecting the filter elements: static discharge. Static charges can build up in a hydraulic system due to friction between the fluid and system components. In this case, the static was burning and damaging the elements, causing them to prematurely fail.

By switching to Schroeder’s ASP® Anti-Stat Pleat Media, the electrostatic discharge no longer caused significant problems for the customer. Here are just some of the benefits from this filter element switch:

Filter Life Increased +5 Months

Oil Service Life Increased +3 Years

$12.2K Oil Cost Savings Per Year

Varnish Mitigation Unit (VMU) Increases Oil Life by 3.5 Years, Saves Nearly 1,000 Gallons Per Year at Waste Incineration Facility

Operations at a waste incineration plant were constantly disrupted by constant turbine problems on startup.

A survey of 22 machines revealed the issues were the result of varnish buildup in the control block, caused by usage of incorrect oil in certain machines and an inexpensive, ineffective return line filter element. Varnish is a byproduct of aging oil, and is accelerated by contamination, temperature extremes, and other factors.

Schroeder Industries implemented a VMU to continually filter the turbine oil and tackle harmful varnish buildup. This not only reduced downtime and increased productivity, it also helped the customer in the following ways:

Oil Service Life Increased +3.5 Years

986 Gallons of Oil Saved Per Year

$12.1K Oil Cost Savings Per Year

Diesel and Beyond: The Future of Fuel Filtration

Text in image reads: "Diesel and Beyond: The Future of Fuel Filtration" with an image of a diesel engine

This article is based on a webinar conducted by Aaron Keck, a product manager in Schroeder Industries’ Fuel Filtration group. This insightful presentation is informed by Aaron’s 13 years of experience in the Diesel Power and Fluid Power Industries.

Growing global energy demands are ‘fueling’ technological advancements in engines and driving the adoption of alternative energy sources. The ripple effect of this evolution has major implications for the filtration industry.

Given the speed of advancement and diversification of fuel sources, and the increasing desire for environmentally responsible energy consumption, what do the futures of diesel and fuel filtration look like?

Despite the growth of alternative fuel technology, all signs point to a continual refinement of diesel technology in tandem with developments in CNG, hydrogen, and electric power. The diversity of technology and fuel sources provide many avenues for new innovations.

1. The Diesel Engine is Here to Stay

Three diamond shapes including a diesel gas pump icon, a hand pumping diesel gas into a metal tank, and an HDP240 onboard diesel fuel filter

Electric engine technology has advanced by leaps and bounds, but industry sources indicate that all electric vehicles are still far off in many applications, from military to commercial.

According to a study conducted by the National Academies of Sciences, Engineering and Medicine examining military applications for electric vehicles, “…all-electric vehicles are not yet practical — at least through 2035.” Jeremy Harsin, the Global Construction Market Director for Cummins Inc., predicts that “In the off-highway space, diesel still has a long runway.”

A variety of factors contributes to the practicality of diesel engines over electric engines in the near term for various applications, including:

  1. Limited electric infrastructure.
    Reliable electric power requires an expansive, efficient power grid. Especially for remote applications such as mining, the infrastructure to sustain such operations does not currently exist.
  2. Lower energy density of current battery technology.
    Pound for pound, current battery technology can’t match the energy density of diesel fuel, which is critical for consistent, reliable, long duty cycles.
  3. Reliability concerns.
    There’s a reason diesel is often a primary backup source for critical operations, processes, and services: Diesel’s proven reliability. In renewable, hybrid power generation systems, diesel is frequently integrated to make up for production shortfalls and periods of high demand.

A long runway for advancement in diesel technology still exists, even as electric and alternative energy technology adoption grows.

As liquid diesel engines evolve, filtration technology must adapt to enable efficient, clean operation. Major considerations include:

Diesel gas pump icon
  1. The sensitivity of new fuel system designs.
    Protecting system components from contamination is increasingly vital as components become more sensitive and precise. Eliminating as much contamination as possible is necessary for increasing component life, maintaining efficiency, and reducing emissions.
  2. Changing fuel chemistry.
    The adoption of biodiesel, diesel blends, and other sustainable fuel sources demands additional considerations in filter material selection. Choosing appropriate metals, coatings, and elastomers ensures that filtration components will not react adversely to changes in fuel chemistry. Rapid prototyping and modular testing are essential for keeping pace with chemical changes.
  3. Maintaining system efficiency to reduce emissions.
    Legislation and broader concerns regarding emissions and carbon footprints calls for filtration solutions that maximize system efficiency, increases energy efficiency, and reduce emissions.

2. Alternative Fuel Demand Will Grow

In the October 2022 Outlook for Energy Report from Exxon Mobil, there was an emphasis on the long-term reduced reliance on oil and shifting demand towards a variety of alternative fuel sources. 

There are three key drivers of this trend:

  1. Technology.
    As alternative fuel technology becomes more viable, affordable, and widespread, adoption increases.
  2. Policy.
    Legislation and environmental agreements on the global and national level, such as the 2015 Paris Agreement and the 2022 U.S. Inflation Reduction Act, provide incentives and regulations that drive alternative energy adoption and control emissions.
  3. Consumer Preference.
    Consumers are increasingly interested in alternative energy sources in their transportation and utilities. A Consumer Report survey conducted in 2018 found that 76% of U.S. residents agree that increasing renewable energy is a worthwhile goal. With technological innovation and government incentives increasing alternative energy accessibility, consumers may be more encouraged to support entities utilizing alternative energy sources or consider adopting alternative energy in their own lives.

While oil will remain a large source of global energy over the next 30 years, the growing shift to alternative fuel sources will drive new technology and demand new tailored filtration solutions.

3. Spotlight on Compressed Natural Gas

Three diamond shapes which include a CNG flare icon, a row of CNG tanks, and the CGF50 compressed natural gas filter

Compressed natural gas, or CNG, is one of the mostly widely used alternative fuel sources for lower emissions and requires specialized filtration solutions. Three major, interconnected applications for CNG filtration come with their own considerations:

  1. CNG Dispensing.
    Commercial last-mile delivery and hub-and-spoke distribution models, which increasingly run on CNG for carbon footprint reduction, are driving an increase in CNG fueling stations.

    Filtration solutions for this expanding infrastructure must maintain a low pressure drop while ensuring optimal filtration to provide consistently clean fuel to these fleets in a timely manner.
  2. Virtual Pipelines.
    For plants and operations far from existing natural gas pipelines, compressors are used to load CNG onto trailers, which are taken to remote industrial sites. This system is referred to as a ‘virtual pipeline.’

    Reducing pressure drop is vital for reducing the energy consumption of these compressors and extending service intervals. Utilizing the latest gas filtration media in a layered, pleated construction, lower pressure drop and higher efficiency can be achieved versus traditional filtration setups typical to these applications.
  3. Oil & Gas.
    Dual-fuel technology, in which an engine is designed to operate on diesel and CNG, is regaining traction in the oil & gas industry and continues to evolve.

    The intensity of oil & gas work environments calls for especially robust filtration solutions which maintain a low pressure drop and are small enough to maximize available space and accommodate two fuel systems. In many cases, appropriate surface treatments and the use of stainless-steel materials where possible are also required to prevent degradation in potentially corrosive environments.

4. Hydrogen Filtration and Transitional Technology Between Liquid Fuel and Electric-Powered Engines

Three diamond shapes containing an icon of a hydrogen molecule, a closeup of a hydrogen pump, and a selection of hydrogen gas filters

In the quest for electrification, hydrogen power is a critical stepping stone. Emitting only water vapor and small amounts of nitrous oxide, hydrogen power is a benchmark for eco-friendly alternative fuels.

In the spring of 2023, Cummins Inc. rocked the industry with the reveal of a fuel-agnostic 15L engine capable of running on hydrogen. This development illustrates that fuel-diversity is an attainable first step in transitioning away from liquid fueled engines and moving us closer to the infrastructure needed to support more alternative energy sources like hydrogen.

As with any fuel, filtration plays a key role in the performance of hydrogen-powered equipment and fuel cells at every stage:

  1. Manufacturing.
    Filtration plays a key role in the manufacturing process, as component cleanliness of fuel cells and battery technology, to compressed gas storage tanks require extremely clean environments to ensure safe and reliable operation in the field.
  2. Generation.
    From the electrolysis process needed to produce the hydrogen, to the compression and storage of the hydrogen, the same requirements of removing contaminants during the handling and storage of the fuel parallel that of compressed gas. 
  3. Refueling.
    Refueling points also require a level of filtration to ensure that the hydrogen introduced into a fuel cell maintains a high purity. 
  4. Charging.
    The stationary equipment used to charge battery electric equipment, or the fuel cell electric equipment use some level of filtration for both the air used in the fuel cell, as well as the hydrogen fuel being consumed.

Developing hydrogen filtration solutions requires special considerations:

Hydrogen molecule icon
  1. Hydrogen embrittlement.
    Solid metals will deteriorate in the presence of hydrogen, so material selection is extremely important for extending the integrity of filters and elements.
  2. Hydrogen molecule size.
    Hydrogen is an exceptionally small molecule compared to other filtered fuels. To secure the system and prevent leaks, seal designs need to be carefully selected and appropriate elastomers used to ensure a consistent, leak-free, and serviceable sealing surface. 
  3. Appropriate filter elements.
    Traditional filter medias used for other liquids and gasses will not withstand the design requirements of hydrogen compression, transfer, storage, or dispensing. Stainless steel is a common choice for hydrogen elements to avoid electrostatic discharge. To prevent fiber migration into highly sensitive, high-pressure hydrogen system components, compressed metal fibers are a common choice for filter media.

Hydrogen presents an exciting, yet challenging avenue for expansion in the filtration industry where we will continue to push the limits of filtration and material science.

In Conclusion: No Linear Path for Fuel Filtration

Four diamond shapes containing: an energy icon, a diesel gas pump icon, a hydrogen molecule icon, and a CNG flare icon

The future of fuels and fuel filtration will not be defined by a clear linear advancement towards renewable fuel sources.

Just as physical currency still exists alongside electronic payments and banking, our energy needs will continue to be satisfied by a range of fuel sources, including diesel and alternative fuels. Advancements in diesel and liquid fuel technologies must continue alongside alternative fuel developments.

How Does On-Site FMaaS Help?

Text graphic reads: Did you know that over 70% of hydraulic system failures are due to contaminated hydraulic fluid?

Did you know that more than 70% of all machine failures can be traced back to contaminated hydraulic oil?

Particulate contamination is extremely damaging to hydraulic equipment, ranging from visible dirt to ‘invisible’ particles only a few microns in size. Constant abrasion from solid particles wears out bearings and seals, damages pumps, and causes valves to stick. Water and gases can also contaminate the hydraulic system via worn seals or by entering the reservoir.

Damage from uncontrolled contamination can lead to costly repairs and lost productivity. Although contamination cannot be completely stopped, it can be controlled through proper filtration. However, developing and executing a filtration plan can be challenging:

  • The equipment required to diagnose and monitor fluid health can be expensive. But, without accurate real-time data, attempts at filtration are only a shot in the dark.
  • Filtration equipment also requires considerable investment.
  • Operating and installing analysis and filtration equipment requires training and expertise. Hiring or training dedicated filtration personnel is yet another expense.
  • Companies may not have the manpower to run their systems at OEM-specified cleanliness levels.

Not every company has the capital or manpower to invest in and manage their own filtration strategy, which is where Schroeder’s Filtration Management as a Service comes in.

How Does FMaaS Work?

With FMaaS, filtration experts from Schroeder Industries will plan, execute, and manage your filtration strategy and filtration equipment. When you participate in FMaaS, protecting your hydraulic systems from contamination becomes one less hassle on your plate.

Step 1: Oil Analysis

Any successful oil filtration program requires accurate diagnostics. An oil analysis will help to determine the health of your system. With the source, type, and quantity of contamination established, a filtration strategy can be developed.

Superior High Flow Coalescing Fuel Filtration with GHCF

GeoSeaql High-Flow Coalescing Filter for superior fuel filtration with catalog link

Diesel Engine Evolution Brings New Challenges

In 2004, the EPA introduced Tier 4 emission standards, requiring reduction of particulate matter (PM) and oxides of nitrogen (NOx) emissions from diesel engines by 90%. These requirements were intended to roll out in stages from 2008-2015, based on engine power category.

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:

Biodiesel icon
  • 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:

Geoseal High Flow Coalescing Filter for diesel fuel filtration
  • 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.

Air Fusion Technology Offers Superior Hydraulic Air Filtration

Graphic reads 'Air Fusion Technology (AFT) View In Catalog.' Shows Air Fusion Technology hydraulic air filter on hexagonal background with splashes of oil.

Hydraulic Air Contamination Has Major Impacts

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:

Diagram of key air fusion technology design elements

  1. The unique filter head design swivels independently of the inlet port, allowing toolless element change-outs.
  2. 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.
  3. 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.
  4. 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.
  5. The de-aeration diffuser shroud significantly reduces fluid turbidity. Less turbulent fluid allows for faster bubble coalescence and improved air filtration.
  6. 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!

Shrink your tank up to 60%

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.

Oil Dehydrator Systems Protect Your Equipment

What Are Oil Dehydrator Systems?

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:

View Product Options:

TDSA – View in Catalog

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.

TDSE – View in Catalog

The TDSE uses the same patented mass transfer dewatering technology as the TDSA, and features an increased flow rate.

The relative humidity of the incoming fluid is continually monitored by an integral AquaSensor (AS) and displayed real-time on the control panel in percent saturation.

NAV – View in Catalog

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

SVD01 – View In Catalog

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.
