137A Coalescent Oil Separator

The 137A coalescent oil separator is specifically designed for CO2 transcritical high-medium- and low-temperature applications. The model 137A has a maximum working pressure of 140bar (2030PSI). This model comes in multiple connection types such as: MPT, BW, and ODS.

The model 137A is designed to remove oil from the refrigeration system and return it to the compressor resulting in shorter compressor run times, reduced energy consumption and the highest possible return on investment. The main purpose of the oil is to lubricate the compressor. When oil circulates through the system instead, it builds up a film on the internal surfaces of the heat exchangers and acts as an insulator. This robs the system of efficiency and raises energy consumption. Coalescing separators are capable of removing 95% to 99% of the oil component of mass flow. The glass fiber filter material is capable of exciting the smallest oil molecules. The fiber material forces the molecules to collide and form larger droplets which fall to the bottom of the separator to drain back to the compressor.

The Model 137A coalescent oil separator is specifically designed for transcritical CO₂ high-medium- and low-temperature applications up to 140 bar. Popular in grocery store sized refrigeration systems.
