Description
The Trane OIL0078 Polyolester Refrigeration Oil 1-Quart is a lubricating fluid formulated to support compressor operation by reducing friction and heat generation in sealed frigid circuits. It circulates with refrigerant and forms a protective film on moving evaporator components to maintain smooth mechanical action. It is added during service replacement and introduced directly into the refrigerant system through service ports or oil charging equipment. In HVAC systems such as commercial air conditioning and refrigeration units, it supports compressor reliability, enhances heat transfer stability, and supports maintaining long-term operational efficiency under varying load and temperature conditions.
