Every manufacturer of refrigeration and air-conditioning compressors and systems has had to re-evaluate the requirements for lubricants. The HFC (hydrofluorocarbon) refrigerants that are replacing CFC (chlorofluorocarbon) refrigerants have a different influence on lubricants which effects both compressor durability and system performance. Other types of refrigerants such as ammonia and hydrocarbons are also alternatives to CFCs, and new lubricants are being evaluated to improve performance in these systems.

A Brief History

The range of refrigeration lubricants being offered today is much broader than ten years ago. This is partly due to the increased use of enviro-friendly refrigerants such as the chlorine-free hydrofluorocarbons. But is also due to a desire by original equipment manufacturers and end users to improve the efficiency and reliability of their refrigeration systems. These influences and others have been quietly changing the requirements and number of lubricants available since refrigeration compressors were first introduced. Read more “A Brief History”
