SEAL ‘N’ DRY converts hydraulic oil reservoirs from open breather systems to an expandable bladder system. Air in the system passes through a desiccant dryer removing moisture.
INTRODUCTION SEAL’N’DRY helps solve oil contamination problems associated with open vent systems.
Ambient air contains moisture and airborne contaminants that enter the breather vent.
Water is the primary contaminant and leads to frequent oil and filter changes and shortened equipment life.
THE SOLUTION SEAL’N’DRY converts an OPEN vent reservoir
to a variable volume CLOSED vent system with
internal dryer and pressure / vacuum relief valves.
This stops ingression and alters the interior
environment to a clean and dry state.
Most new and existing oil containing open vent systems can benefit from the use of SEAL’N’DRY.
This includes other fluids and gear lube oil systems.
The bladder size is a function of air and oil expansion due to temperature changes and system displacement. See Table 1.
SEAL ‘N’ DRY comes complete with a variable
volume bladder device, moisture indicating desiccant dryer, pressure/vacuum relief valves, adapter and tubing. All items are enclosed in a lightweight housing. Stainless steel, painted steel, non-metallic HDPE, custom and special type enclosures are available.
For use on low pressure oil reservoir systems that can safely operate within plus or minus 2 psig.
Sized to suit cubical expansion
Locate above top of oil reservoir. See installation instructions.
Available in lightweight stainless steel, high density polyethylene HDPE and other materials.
Spin-On type available for small size units. Remote Mounting type is Standard.
INSTALLATION Simply replace the existing breather vent cap with a Spin-On or Remote mounted SEAL’N’DRY unit.
