The Cool Compression series of industrial refrigeration single screw compressors from Vilter Manufacturing use direct contact heat transfer to cool the compressor oil right in the oil separator, eliminating the need for an air cooler. The compressors reduce oil carryover and eliminate oil foaming by using a liquid ammonia layer in the separator to cover the heavier oil. According to Vilter, the units also have fewer components, which reduces overall maintenance over the life of the unit.
