How does a 920 Series Oil Separator work?
Regular impingement screen separators use a screen and the concept of “expansion of gasses” to slow mass flow and agglomerate the oil to fall to the bottom of a reservoir. Temprite engineers employed this methodology in 1948 when we designed the first oil separators for refrigeration. Virtually all oil separators are copies of this original design. Centrifugal separators are no more efficient than impingement screen separators. They’re velocity dependant which means the efficiency drops off when the compressors are cycled off or unloading, (velocity drops). Tests run by Emerson’s Climate Technologies Group at Copeland’s test labs showed that the old tried and true 500 and 600 Series oil separators were more efficient at separating oil than the centrifugals. The 920 Series separators continue to work at 99 percent efficiency throughout the compressor’s variable load regardless of velocity.
