TotalEnergies LUNARIA SK 55 – Synthetic Refrigeration Compressor Oil
LUNARIA SK 55 is a synthetic refrigeration compressor oil based on alkylbenzene, designed for use with CFC and HCFC refrigerants. It is also suitable for lubricating heavily loaded reciprocating air compressors with discharge temperatures above 200 °C. With its excellent miscibility with refrigerants such as R12, R502 and R22, it performs reliably even at very low evaporating temperatures.
Product Advantages
• High chemical stability when mixed with refrigerants
• Low foaming tendency
• Excellent lubricating properties
• Very good miscibility with refrigerants and secure oil return down to –60 °C evaporator temperature
Typical Applications
• Refrigeration compressors with CFC and HCFC refrigerants
• Reciprocating air compressors with discharge temperatures >200 °C
• Systems with low evaporating temperatures down to –60 °C
