COMPRESSOR PROTECTIVE DEVICES

Applications

The Coalescing Oil Separators are typically used on larger industrial

refrigeration systems and rely on a coalescing element to remove oil from the

hot gas. Once the filtering element becomes saturated with oil it will begin

accumulating within the vessel. An optional float valve can be attached to

control oil flow to an Oil Management System or straight to a compressor

crankcase.

Henry Technologies’ Coalescing Oil Separators are suitable for use with

Ammonia, HCFC and HFC refrigerants, and their associated oils, as well as

other industrial fluids non-corrosive to steel.

The function of a Coalescing Oil Separator is to remove oil from the

discharge gas and return it to the Compressor either directly or

through an Oil Management System.

Technical Specifications

Maximum working pressure = 400 PSI (27.5 Bar)

Allowable operating temperature = -20°F to +230°F (-29°C to +110°C)

Henry Technologies’ Coalescing Oil Separators are constructed in

accordance with ASME Section VIII. Additionally, Coalescing Oil Separators

are designed and registered for use in Canada. Please contact Technical
