Refrigerator/CompressorOils
PRODUCT DESCRIPTION.
KESOON/L-DRA/Arefrigerator compressor oils are quality hydrotreated oils designed for use as refrigerator compressor lubricant, with traditional refrigerants. They are highly stable and are essentially wax free. They have long histories of satisfactory service in many types of equipment and are approved by most manufacturers for both factory fill and maintenance fill of their equipment
Application：
KESOON/L-DRA/Arefrigeration oils can be used in virtually any installation regardless of compressor or evaporator temperatures. They are ideally suited for low temperature systems where evaporator temperatures are below -18°C including residential and commercial refrigeration and air-conditioning systems. Particularly with HCFC and CFC refrigerants such as R-22, R-502 and R-12. Furthermore they perform excellently with natural refrigerants such as R-717, R600a and R-290.
Features
l Low pour points and Freon floc points that prevent low temperature fluidity loss.
l Excellent oxidation stability which reduces oil thickening and deposit formation.
l Excellent lubricity with high viscosity index which guards against wear of compressor parts.
l Outstanding viscosity/temperature characteristics.
l Excellent thermal stability minimizes formation of gum, varnish, and sludge.
