Suniso Oils are specially imported refrigeration and air conditioning compressor oils formulated on highly refined, dewaxed naphthenic base stocks, refinery treated to enhance thermal stability.

The Suniso GS oils are designed for systems where the refrigerant is fully miscible (freon and methylene chloride) or partially miscible (sulfur dioxide) with the oil. The 4SA grade is designed for systems using ammonia as refrigerant, which is immiscible with the oil.

Suniso 4SA
A modified version of Suniso 4GS developed for ammonia refrigeration systems where temperatures and pressures are frequently higher.
