Application

Refrigeration Lubricants

KOREOX products demonstrate excellent compatibility with automotive air conditioning refrigerants such as R-134a and R-1234yf, making them ideal base oils for refrigeration lubricants due to their superior lubricity.
Compared to other synthetic or mineral base oils, they provide outstanding wear reduction, enhancing refrigeration system efficiency and lowering maintenance costs.
Their high viscosity index ensures smooth operation under extreme temperatures, while the use of low-viscosity base oils contributes to energy savings.
