Head Space Dehydrator: Stop Water Contamination Before It Happens!



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 equipmentโ€™s 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:

  1. The Head Space Dehydrator assembly pulls ambient air into the chamber through a series of particulate breathers.
  2. 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.
  3. As the moist air is displaced, the opportunity for water contamination via condensation is reduced.


Specifications:

Flow Rating:Max flow rate 282 cfm (7985 lpm)
Blower:1/2HP blower with 220-275/380-480V-60Hz-3 phase motor
Breathers:Uses 4 breathers which include -0.5 psi (-0.035 bar) differential pressure indicators

Features & Benefits

  • Cost effective, reliable solution for water ingression
  • Improved oil cleanliness
  • Increased lifespan of oil and components

Markets & Applications

Ideal for industrial applications where water contamination may be introduced to the reservoir head space, particularly:

  • Steel & Primary Metals
  • Pulp & Paper Production
  • Bulk Storage
  • and more!

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, itโ€™s 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.

You can expect the following if water contamination isnโ€™t 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.

Introducing the GPT: Superior Filtration for Cold Start Conditions

Header image featuring GPT filter images on an oil splash background. Text reads: Schroeder GPT. Protect your system from bypass contamination with this innovative filter. Contact the experts.

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?

Image of GPT filter with a splash of oil.

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.

Diagram showing the GPT filter reusable diverter cap, separated from the filter element.

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.

Enhance Hydraulic Equipment Through Tank Optimization

How can tank optimization benefit you? Ask the experts.

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.

Schroeder Industries family of hydraulic tanks, TNK Series

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.

AutoFiltยฎ RF9: Superior Process Filtration for Hydroforming


Header graphic with text reading: Superior Filtration for Hydroforming. How can your business benefit from the AutoFiltยฎ 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.

Save Oil Through Filtration and Reduce Your Carbon Footprint


An operationโ€™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:

Growing global energy demands are โ€˜fuelingโ€™ 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

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, “โ€ฆall-electric vehicles are not yet practical โ€” at least through 2035.” Jeremy Harsin, the Global Construction Market Director for Cummins Inc., predicts that โ€œIn the off-highway space, diesel still has a long runway.โ€

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 canโ€™t match the energy density of diesel fuel, which is critical for consistent, reliable, long duty cycles.
  3. Reliability concerns.
    Thereโ€™s a reason diesel is often a primary backup source for critical operations, processes, and services: Dieselโ€™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

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 โ€˜virtual pipeline.โ€™

    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

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

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.
