Because of their rotating components, all compressors require lubrication. Early designs of reciprocating compressors utilized a “splash system” in which the “throw” on the crankshaft would dip into an oil pool in the crankcase and splash it over the moving parts as the shaft rotated. Today, reciprocating compressors used in industrial refrigeration utilize “internal force feed” lubrication […]
Ammonia Captured in this week’s edition of the Ammonia Week in Review… Oak Bay Rec Centre Reopens After Ammonia Release – The district said the chemical was captured and contained by backup system, and there is “no safety risk to the public.” […keep reading] Refrigeration Cycle: Open Drive vs Hermetic – Another way compressors are categorized is by […]
Another way compressors are categorized is by the way the motor and compressor are mounted and contained. With “open drive” compressors, the motor and the compressor are mounted separately. The shaft that connects the motor to the compressor must be sealed to prevent refrigerant leakage from the compressor. Open-drive compressors are widely used in industrial applications. An […]
The Search Is On in this week’s edition of the Ammonia Week in Review… Ammonia Leak Contained at Murfreesboro Facility; Crews Monitoring Air Quality – An ammonia leak at a Murfreesboro facility has been contained after prompting an evacuation Friday afternoon.

“Rotary vane compressors” are a third type of positive displacement compressor. The design of these machines makes them well suited for “high volume”, low-pressure differential applications. As such, rotary vane compressors are essentially limited in application as “booster compressors” in two-stage systems. The maximum compression ratio of a rotary vane compressor is 4:1. Like screw compressors, […]
