SOSILNA POE Refrigeration Compressor Fluid is a Refrigeration Fluid for HFC, HCFC and HFO Systems. Provides unsurpassed performance in chlorine-free HFC refrigeration applications. This advanced formulation provides superior protection for HFC refrigeration systems, exceptional chemical and thermal stability, and very long service life. Utilizes a proprietary combination of advanced friction modifiers and anti-wear additives that bond to metal surfaces inside the compressor. Creates an extra layer of protection and lubrication that dramatically reduces friction and wear, resulting in increased compressor efficiency, energy savings, and extended compressor life.
