When asked what the oil in an ammonia screw compressor is responsible for, most people immediately answer, "lubrication." While that's certainly true, lubrication is only one of several critical functions oil performs within the compressor. This oil lubricates bearings and moving components, absorbs heat generated during compression, and creates a dynamic seal between the rotors and compressor housing. This sealing effect reduces internal leakage, improves volumetric efficien
