As refrigerants evolve, compressor lubricants must keep pace. The wrong oil-refrigerant combination can reduce efficiency, damage compressors, and shorten system life.

Oil Traps Protect the Compressor

All vapor-carrying lines in a system should have an oil trap to ensure proper oil return

This line of polyolester (POE) lubricants is specifically designed for air conditioning and refrigeration compressors. These lubricants are formulated from high quality materials, using a customized manufacturing process.

Inside Refrigerant and Oil Relationships

The two must be soluble in one another

John Tomczyk

Under normal conditions, there will always be a small amount of oil that escapes a compressor’s crankcase and is circulated with the refrigerant throughout the system. It is for this reason that refrigerant oil and the refrigerant itself must be soluble in one another. It is the velocity of the circulated refrigerant that carries the oil back to the compressor’s crankcase. If the two were not soluble in one another, this phenomenon could not happen.
