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
reservoirs.
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.
