TMR - Reservoir Headspace Dehydrator
HY-PRO FILTRATIONA
EHC Water Removal
Reservoir headspace dehydrator for
EHC systems using phosphate ester.
Eliminate the primary catalyst of Acid
production in EHC fluids (Hydrolysis) &
optimize phosphate ester performance.
TMR controls the moisture equilibrium
in the reservoir. Dry air mass transfer
extracts dissolved water from the fluid.
Minimize fluid degradation with TMR
maintaining water levels < 200 ppm.
Equilibrium (Oil and Headspace Air)
With passive breather devices and no continuous
exchange of air through the reservoir headspace the
air above the oil will achieve thermal and moisture
equilibrium with the oil. At the top of the reservoir
headspace the air cools yielding condensation and
recontamination of the water into the oil.
TMR is an active breather system that maintains the
air in the headspace at a dry enough level to ensure
that condensation cannot take place. As the dry air
transfers through the headspace at RH < 5% the oil
gives up its water striving to achieve equilibrium with
the dry air in the headspace.
The TMR also promotes air release in the EHC
reservoir providing an additional degassing function.
Installation
If there is a headspace evacuation system on the
reservoir to which the TMR is being added this
system should be disabled and any reservoir holes
should be sealed with the exception of the breather.
How TMR Works (see illustration page 2)
A slight positive pressure is created to prevent water and
debris from migrating into the reservoir (leak points) . TMR
introduces extremely cleaned and dried air free of oil, water
aerosols or particles with 150°F dew point
suppression. The dew point suppression enables the TMR
to take normal compressed air at +80°F dew point and
reduce it to -70°F dew point.
The TMR inlet is located as far from the reservoir breather
or vent as possible. The clean, dry air enters the reservoir
above the oil surface and flows toward the breather. As
the air sweeps through the reservoir, moisture from the
headspace and oil is adsorbed into the air. The air is then
exhausted through the breather or vent. If there is no
breather a Hy-Dry desiccant breather should be installed to
dry and filter any necessary make-up air.
Total EHC Fluid Solution
The total EHC solution of TMR, ICB (Ion Charge Bonding)
acid scavenging elements, DFE rated glass media filter
elements for particulate control, and ECR electrostatic
oil cleaner will provide years of trouble free EHC system
operation when installed together.
