As hydraulic oil oxidizes and degrades, a sticky substance known as varnish is deposited throughout the hydraulic system. Changing oil chemistry in modern hydraulic systems and the high pressure & temperatures achieved during equipment operation are leading to increased varnish deposits.
How Does Varnish Affect Your Hydraulic System?
Varnish accumulation in a hydraulic system causes a variety of potentially serious issues:
Varnish deposits on hydraulic valves and other components can cause the components to stick, or even become fully jammed.
The operating temperature of the machine may increase as the machine tries to compensate for its reduced efficiency, which can accelerate oil degradation and cause overheating.
Machines may malfunction at critical moments as components lose efficiency or fail entirely, leading to lost productivity or safety hazards.
Hydraulic filters and filter elements may become prematurely blocked due to varnish buildup.
Lost productivity and frequent repairs or part replacements due to varnish buildup can become very costly.

One of the most debilitating problems a vessel can face at sea is an unexpected loss of control. In rough seas, working engines can mean weathering the storm or succumbing to it. Shipping delays due to engine failures and repairs can have a cascading impact on supply chains and result in major disruptions and financial loss. More importantly, loss of control can have devastating consequences on crew and bystander safety.
When considering ways to prevent an unexpected loss of power for marine applications, controlling fuel contamination is a very effective way to eliminate one of the greatest factors affecting diesel engine reliability today.
What Causes Fuel Contamination in Marine Applications?
Fuel systems in marine applications are particularly vulnerable to water contamination due to the operating environment and vulnerabilities in the fuel supply chain.
By virtue of operating at sea, on the coast, or in rivers, ships are exposed to high levels of humidity and water, which is the most common type of contamination that sea-going fuel systems face.
Diesel fuel is transported through a long network of refineries, bulk fuel suppliers, and dispensing stations before reaching its destination. At every stage, water, humidity, bacteria, pollen, and other contaminants can enter through open breathers, improperly sealed vessels, and other points of ingress.
Fluctuations in temperature can result in high levels of free water in a fuel system, which is more damaging than water that has dissolved into the fuel.
How Can Fuel Contamination Cause Engine Failure?
Contamination can affect engine operations in a variety of ways:
Buildup of bacterial sludge in the fuel due to water and bacterial contamination, also called diesel bug, can plug the engine filtration system and starve it of fuel
Small amounts of particulates and water can wear out an engine’s components over time, reducing its overall efficiency and eventually causing the engine to fail.
What Other Impacts Can Contamination and Contamination-Related Damage Have?
Besides total engine failure and its potential consequences, contamination has a range of direct and indirect impacts on equipment and operations:
Costly maintenance and repair of engines and equipment
Increased fuel-related expenses between acquiring clean fuel, disposing of contaminated fuel, and remediating/polishing contaminated fuel
Reduced fuel economy due to inefficiencies in the engine/high pressure common rail injection systems caused by contamination
Reduced engine and equipment longevity
Overall reductions in vessel or fleet profitability due to compounding expenses and downtime for repairs
How Can I Control Diesel Contamination?
Having a system in place to proactively monitor and prevent contamination where possible, plus a solution to remediate whatever contamination occurs, is key for controlling fuel contamination and protecting your engine.
Obtain fuel from a reputable source. Fuel is often contaminated before it enters a shipโs fuel system, but reputable suppliers who are familiar with contamination and take fuel cleanliness into consideration will provide higher quality fuel and prevent large, immediate influxes of contamination.
Ensure storage/fuel tank cleanliness. Before filling a fuel tank or bulk storage tank, be sure the tank is clean and dry.
Take precautions when transferring fuel/filling your system. Water and other contaminants are most likely to ingress during fuel transfer, so ensure that your transfer system is properly sealed.
Monitor the fuel quality levels of your storage tanks to determine the condition of the fuel being delivered to your engine and remediate or replace contaminated fuel before it can affect your equipment. Test kits such as Schroeder’s Diesel Fuel Quality Analysis Kits can provide important insights into the condition of your fuel, especially if you’re experiencing issues consistent with fuel contamination.
Closely monitor your fuel water separators and engine filters and empty them as often as needed. But remember: don’t rely solely on these separators and filters to completely resolve your contamination issues!
Acquire a fuel polishing system. A fuel polishing system/kidney loop attached to your system or to your storage tanks can help address contamination in real time.
Some degree of water contamination is inevitable, especially in a marine setting. However, proactive maintenance and preventative measures will significantly reduce your chances of catastrophic contamination-related equipment failure!

Contact-Blog-Water Contaminated Diesel In Marine Applications: Fix It With Filtration!
Compressed Natural Gas, or CNG, is one of the best known and most widely used alternative fuel options currently available. As CNG and CNG-powered technology proliferates, as with any fuel, filtration is necessary to ensure optimal fuel quality and operational efficiency.
In this post, we explore:
The projected growth of CNG
Examples of CNG applications
The unique considerations of CNG filtration
The products that Schroeder Industries has engineered for excellence in the realm of CNG filtration
CNG Surge: Compressed Natural Gas Market Projected to Grow
According to a June 2023 report from The Business Research Company, Compressed Natural Gas Global Market Report 2023, the global CNG market was valued at 147.16 billion USD in 2022. By 2027, the market is expected to grow 83.5%, for a total estimated value of 269 billion USD.
CNG is one of the major players in alternative fuels for several reasons, including:
1. Improved sustainability compared to traditional fuels.
It also delivers comparable torque and power to traditional diesel engines, making it viable for intensive work such as construction and mining.
3. Relative ease of integration into current systems.
CNG can largely utilize existing technology such as vehicle designs and transportation infrastructure, making transitions and retrofits more straightforward compared to other alternative fuel sources, such as electric power.
Part of this growth in the compressed natural gas market is being driven by CNG fueling and other related applications, including power generation and fueling CNG-powered vehicles for commercial fleets. Delivery vehicles, refuse collection trucks, and other commercial vehicles are seeing increased adoption of CNG. Compressed gas dispensing stations and virtual pipelines are expanding to satisfy the growing need for CNG fuel.
In order to ensure optimal performance of both CNG dispensing units and the vehicles that utilize it, CNG must be filtered to remove damaging contamination such as water vapor, residual oils, and solid particulates.
CNG Filtration 101
Despite being a compressed gas, CNG is also susceptible to contamination and requires filtration just like diesel and conventional liquid fuel to maintain its quality.
Water Vapor: Water vapor is found in all compressed gases and air. When under pressure, the water vapor becomes more concentrated.
Oil: Oil can leach into the compressed gas via lubrication in the compressor system. Hydrocarbon contamination is also present even in gas drawn through oil-free compressors.
Solid Particulates: Compressed gas systems can also ingest particles of rust, dirt, and other solid contaminants, just like a liquid fuel application.
Just like conventional fuel contamination, contaminated CNG can negatively impact equipment and its performance:
Reduced Desiccant/Dehydrator Absorption: Compressed gas systems include dehydrating components, but high contamination levels can more quickly overwhelm these dehydrators.
System Component Wear: Sensitive system components, fuel injectors, and seals can be abraded and damaged overtime by contaminants, leading to costly repairs and replacements.
Reduced Efficiency Overall: Worn components reduce operational efficiency and increase maintenance-related downtime for CNG-powered equipment.
And More!
However, filtering compressed gas requires extra consideration compared to conventional liquid fuel. Adequate gas filtration must, among other things:
Account For Different Gas Types. Filter housings size selection must consider not only the system flow but also the type of gas as well as the operating pressure and temperature of the system. ย
Account For Smaller Gas Molecules. Gas molecules are much smaller than liquid fuel molecules, so material selection and porosity are a major consideration in filter construction. A gas filter must be exceptionally well-sealed and utilize low porosity materials. Ductile iron and aluminum are common material choices for CNG filters.
Tackle Ultra-Fine Particulates. Contamination in compressed air is often under 1 micron in size, which is substantially smaller than typical contamination in liquid fuels. Gas filters must be capable of trapping tiny particulates without compromising the differential pressure in the compressor system.

Over the last decade, users of hydraulic systems noticed a sharp increase in unusual failures and contamination within their equipment, including:
Burned and discolored filter elements
Rapid oil degradation
Prematurely worn, damaged components
Electrical arcing outside of the system
The culprit? Electrostatic discharge, also known as ESD, was becoming more frequent within hydraulic equipment. Static buildup is already a known issue, but why was it suddenly happening more often, and to greater extremes?
Behind the ‘Electrifying’ Increase in ESD
Fundamentally, static discharge in a hydraulic system is caused by frictionโjust like how shuffling across carpet in thick socks allows you to lightly zap someone else with static electricity. Oil may be a lubricant, but there is still some friction between hydraulic fluid and the filter media it passes through, and thus, static buildup can occur.
In a system with highly conductive hydraulic fluid or oil, this static buildup is more easily absorbed and evenly distributed. This prevents the worst effects of electrostatic discharge. However, environmental standards driving changes in oil composition meant that low conductivity oil was becoming more widespread.
Group I โLightly Refinedโ Oils were once the most common class of hydraulic fluid.
These oils contained aromatics and heavy metals. Due to the presence of heavy metals, Group I oils have high electrical conductivity.
However, the heavy metals within Group 1 oils are mostly toxic. Due to this toxicity and the potential threat to the environment, Group 1 oils do not comply with newer, international environmental standards.
Group II & III โHydrocrackedโ or โSyntheticโ oils are replacing Group I oils as a more eco-friendly alternative.
Group II and III oils contain no toxins or carcinogens, as the toxic heavy metals have been removed.
Due to the lack of heavy metals, these oils have much lower electrical conductivity than Group 1 oils.
Between 2012 and 2020, the global market share of Group 1 oils fell by half, from 51% to roughly 26% of hydraulic oils in use. This trend is expected to continue. While moving away from Group I oils is much better for the environment, the proliferation of low conductivity oils led to more electrostatic discharge in hydraulic systems.
Effects of Electrostatic Discharge on Hydraulic Systems
Electrostatic discharge and static cause a variety of serious issues in hydraulic systems, including:
Damaged elements. Scorched, degraded filter elements are a hallmark of static buildup in a hydraulic system.
Increased contamination. When damaged, filter elements become unable to filter out contamination as intended, and the filter element itself may become a source of contamination as it degrades.
Reduced oil and component life. The increase in contamination and compromised filtration drastically reduces oil life and increases component wear.
Formation of sludge and varnish. As oil rapidly degrades, varnish is deposited in the system, affecting system function.
Fire risk. High amounts of ESD can potentially cause deflagration, or combustion of gas within the hydraulic reservoir.
Arcing and discharge outside of the system. In extreme cases, the electrostatic discharge can become so intense that it becomes an electrocution hazard to workers, as well as damaging to surrounding equipment.
Anti-Static Solutions from Schroeder Industries
Anti-Stat Premium and Anti-Stat Media from Schroeder industries are engineered to combat static buildup while providing robust filtration. Because levels of ESD can vary based on factors like fluid type and temperature, two levels of protection are available.
Both offer virtually the same efficiency as Schroederโs standard, exceptionally powerful microglass media. For superior protection from both typical particulate contamination and the effects of electrostatic discharge, look no further!
NEW: Anti-Stat Premium
Anti-Stat Premium: Supercharged Static-Busting Capabilities For Extreme ESD
Specially formulated media dissipates electric charges before they can begin damaging your system
Eliminates all static buildup at the source
Effective for even the most critical cases of ESD, tackling conductivity values lower than 100 pS/m
See how these customers benefited from the static-suppressing characteristics of Anti-Stat Media!
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.
A Schroeder expert immediately identified the signs of static discharge in the hydraulic system. As the elements were burned and degraded by the electrostatic buildup, they failed prematurely, forcing the customer to swap out elements much sooner than usual.
Switching to Anti-Stat Media took the shock out of their system, extending their filter life and leading to substantial savings!
An automotive plant contacted Schroeder Industries when, after switching to a new hydraulic oil, their oil lifespan dropped by as much as 80%.
The customer’s new oil blend was zinc and ash-free, meaning its conductivity was lower than their previous hydraulic oil. As we’ve discussed, the lower a hydraulic fluid’s conductivity, the more likely static buildup is to occur!
Burn marks and varnish on the customer’s used elements confirmed that electrostatic discharge was building up in the customer’s system. By switching to Anti-Stat Media, the customer was able to get the most out of their oil and more!
Introducing the latest in Schroeder Industriesโ line of powerful in-tank filters!
Using the same cutting edge technology as the Schroeder AFT, the new AFTF provides all the best qualities of Air Fusion Technology with stabilized, fixed-head porting.
Hereโs just some of what makes the AFTF one of the most powerful deaerating in-tank hydraulic filters available:
Exceptional deaeration capabilities. Air Fusion Technology reduces fluid velocity and encourages bubble coalescence for substantially more effecting deaeration than other in-tank filters currently available.
Fixed head allows for a breather attachment. The stabilized porting allows the addition of an external breather, further increasing the deaeration potential.
Provides filtration even in bypass. The specialized bypass valve in the head of the filter allows the filter to function even while in bypass for greater filtration efficiency.
Potential for reservoir downsizing. The deaeration of the Air Fusion Technology is so efficient that it may be possible to downsize your hydraulic reservoir by up to 60%!
Most hydraulic reservoirs in major industries including pulp & paper, primary metals, and more feature a pocket of open space between the fluid level and the top of the reservoir. This open space, known as head space, fills with moisture as humid air ingresses via faulty seals, vents, and other entry points.
As the moisture builds in the head space, water condenses at the top of the reservoir, eventually coalescing and falling into the oil.
This water contamination can cause a range of serious problems which can impact your equipmentโs efficiency and may require repairs, including:
Rust
Cavitation
Sensor failures
Reduced oil lubricity
How Schroeder’s Head Space Dehydrator Helps:
Dewatering units such as the Triton Dehydration Stations are excellent for targeting water contamination when oil has already become saturated, but preventing contamination before it reaches critical levels is ideal.
The new Head Space Dehydrator is designed to combat moisture in the head space of a hydraulic reservoir before it contaminates the oil. This unit is permanently installed on a hydraulic reservoir so that humidity inside the reservoir can be managed continuously.
Here’s how it works:
The Head Space Dehydrator assembly pulls ambient air into the chamber through a series of particulate breathers.
The clean, dry air is then blown through the head space above the fluid level, displacing and venting the moist internal air though existing ventilation points.
As the moist air is displaced, the opportunity for water contamination via condensation is reduced.

Water Contamination Can Damage Your Hydraulic System
Water contamination in hydraulic systems is a common problem, which can severely reduce the life of hydraulic systems and fluids. If your hydraulic fluid appears milky when sampled, itโs likely that your system is experiencing high levels of water contamination.
Water ingression can occur in two primary ways:
Ambient humidity, which can ingress into the reservoir headspace and condense into the oil. Humidity can vary depending on the location and season, so pay attention to the conditions your equipment operates in and monitor your fluid condition accordingly.
Pre-contamination of new fluid due to poor storage. Be sure to examine any new fluid for water contamination before introducing it into your hydraulic reservoir.
Liquid contamination in your hydraulic reservoir can cause a variety of serious problems, some irreversible.
You can expect the following if water contamination isnโt controlled:
Due to its chemical composition and density differing from oil, water can affect compressibility, impacting operational efficiency.
Water reduces oil lubricity and can lead to varnish buildup.
Water can also cause corrosion and oxidization in the system. Cavitation and damage to metal surfaces in the system may lead to costly replacements and increased downtime.

Schroeder Success: See How This Customer Saved!
Don’t just take our word on the effectiveness of the Triton Dehydration Stationยฎ series. Review the case study below to see how a real customer benefited from these advanced dehydrators!
When an automotive parts manufacturer found high water levels in the hydraulics of a critical hydraulic press in their facility, they needed a solution quickly.
With the very close timetables of automotive part production, any downtime could be devastating to their operationsโbut solving their water contamination issues required an unobtrusive fix, too.
With a rental TDSE from Schroeder Industries, the customer was able to resolve their contamination issues, reduce their oil consumption, and maintain uptime without unduly interrupting operations.
In fact, the performance of the TDSE was so impressive that the customer ultimately purchased their own TDSA to maintain fluid quality and ensure continued high performance!
Schroeder Industries works tirelessly to provide innovative, effective filtration solutions. The GPT is a new hydraulic filter engineered to resolve a common problem with similar filters on the market: contamination from the bypass.
What makes the GPT the ideal hydraulic filter for cold start conditions?
When a hydraulic machine is shut down and the fluid stops flowing, contaminants will settle loosely onto the filter.
In cold start conditions, when the viscosity of the hydraulic fluid increases, the high differential pressure will force the filter into bypass. Until the machine and fluid warms up, thus lowering the viscosity, the fluid will bypass the filter and enter the hydraulic system directly.
Competitive filters currently available in the market have the bypass located low or within the element, where contaminants have settled during shutdown. If the system starts in bypass, all of that dirt is forced into the system without being filtered, flooding the system with harmful contaminants.
Unlike these other filters, the GPT bypass is located up top, in the diverter cap. This keeps the contaminants settled in the bottom of the filter from entering the system through the bypass.

Reusable diverter cap reduces landfill waste for a more sustainable filter design.
An unfortunate reality of filtration is the disposal of used elements, which contributes to the waste stream.
Keeping with the principles of our Energy Sustainability Initiative, Schroeder Industries is always looking for more sustainable angles in our product designs.
Our engineers saw the opportunity to reduce waste in our GPT design by developing a reusable diverter cap. Typical filters discard the diverter cap along with the filter element, but the reusable GPT design reduces the amount of waste material being disposed of.
With the GPT, element changeouts are fast and easy, and the Lock & Key Quality Protection ensures that only the highest-quality elements are being used.

Rising oil and fuel costs, trends towards electrification, and overall concerns about sustainability across virtually every industry are driving an increased push for improved efficiency in the designs of hydraulic equipment.
One area where great opportunities for improvement lie is with the hydraulic tank. Due to inefficient designs, many machines operate with oversized hydraulic tanks containing more oil than needed.
Many benefits can be realized through tank optimization, including:
Increased energy efficiency
Overall machine weight savings
Steel and oil savings per machine
CO2 emission reduction
Tank downsizing
Additional machine space for other features
Read on to learn more about the benefits of optimizing your hydraulic reservoir, and how Schroeder Industries can help:
What Is Tank Optimization?
The goal of hydraulic tank optimization is to reduce the reservoir size and thus reduce its fluid volume. Two main factors determine how much a tank can be optimized:
Volume Utilization. In a suboptimal reservoir design, ‘dead zones’ can appear, where fluid stagnates and is not effectively utilized by the system. In a properly designed tank, every cubic inch of the hydraulic fluid should circulate within the reservoir. Dead zones can be detected by digital simulations, and are a strong indicator that tank optimization is needed.
Fluid Velocity. Fluid velocity impacts how well a tank can de-aerate, or release trapped air from within the fluid, and prevent new air from entering the fluid due to splashing. Increased air contamination causes a variety of issues within hydraulic systems, decreasing operating efficiency and component lifespan. Fluid velocity can be reduced through improved in-tank filtration and adjusting the structure of the hydraulic tank itself.
The Benefits of Hydraulic Tank Optimization
Here’s some of the ways optimizing a hydraulic tank design can benefit both OEMs and end users:
Cost Savings. Downsizing a reservoir with tank optimization means less steel and oil are needed upon initial construction, reducing up front manufacturing expenses for OEMs. Additional savings are passed on to end users, who will need less hydraulic oil to run the equipment over its lifetime.
Improved Energy Efficiency. A smaller reservoir with reduced fluid volume reduces the overall weight of the equipment, translating to improved energy efficiency. Lower fluid volume also reduces warmup time in cold start conditions. Any improvements in energy efficiency are especially important for electric-powered equipment, which relies on more limited battery power.
Increased Machine Space. A smaller hydraulic reservoir can allow overall downsizing of the equipment or make way for additional improvements to the design. Larger batteries or fuel tanks, cooling units and other beneficial modifications can be made when space is freed up within the machine.
Sustainability Benefits. Tank optimization reduces the carbon footprint of an operation in several ways:
1. By downsizing a reservoir, less hydraulic oil must be produced and then disposed of, reducing the emissions from both the initial manufacturing of the oil and lowering the amount of waste oil per machine.
2. The carbon footprint of initial construction is also mitigated by the reduction in materials needed to create the reservoir itself.
3. Improvements in fuel efficiency for diesel and other fossil fuel-powered equipment reduces CO2 and other harmful emissions overall.
4. Finally, the increase in energy efficiency and available machine space can open up avenues for electrifying equipment, or improving the performance of electric-powered machines, which are at the forefront of sustainable equipment.
The benefits of optimizing your tanks are clear, and the filtration experts at Schroeder Industries can help you get the most out of your reservoir.

An OEM customer producing stump grinding machines for the forestry industry came to Schroeder Industries searching for updated filtration solutions.
An engineering analysis of their fabricated tanks found that not only were they heavy and prone to weld cracks: The volume utilization was subpar.
Further testing concluded that the existing Schroeder TNK12 would provide equivalent deaeration performance to the customer’s current tanks with a 40% reduction in tank volume.
This resulted in substantial savings on both oil and tank production cost in their stump grinder manufacturing:

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.
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:
Why is an AutoFiltยฎ RF9 from Schroeder Industries the best choice for your hydroforming application?
The AutoFiltยฎ RF9 is Schroeder’s first choice for filtration in hydroforming applications. Already, the RF9 has seen great repeat success in the hydroforming division at one of the worldโs largest automotive frame manufacturing plants.
Here’s what makes the RF9 so effective:
Super fine filtration with minimal pressure loss. When filtering process fluid or water for a high pressure application, itโs critical to both achieve the lowest micron filtration levels as possible while minimizing pressure loss. The RF9 is capable of filtering down to 5 microns in a standard hydroforming setup.
Eliminates costly, disposable cartridges. The automatic back-flushing mechanism within the RF9 cleans the re-usable filter elements in under a minute, with minimal interruption to the filtration process.
