Head Space Dehydrator: Stop Water Contamination Before It Happens!

Leave a Comment

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 equipment’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.


Flow Rating:Max flow rate 282 cfm (7985 lpm)
Blower:1/2HP blower with 220-275/380-480V-60Hz-3 phase motor

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, it’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 isn’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.

The Triton Dehydration Station® series 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.

Schroeder Success: See How This Customer Saved!

Don’t just take our word on the effectiveness of the Triton Dehydration Station® 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 operations—but 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!

Introducing the GPT: Superior Filtration for Cold Start Conditions

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.

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.
