REFCOM MRL Rvn no : 1

Compressor lubricant for CFC refrigeration systems

Description

REFCOM MRL is formulated for use in refrigeration systems that use chlorinated fluorocarbon refrigerants. It is a highly refined naphthenic oil with excellent low temperature properties and a very low wax content in order to avoid flocculation problems in service.

Application

Recommended for general purpose lubrication of refrigerator compressors working with CFC (chlorinated fluoro-carbon) refrigerants such as R11 and R12. It may

also be used for HCFC (hydro chlorinated fluorocarbon) refrigerants such as R22,R123, R-124, R-141b, R142b, R-502 and

Methyl Chloride, Carbon Dioxide (R-744) and Ammonia (R-717) at moderate temperatures. Coolmax CFC is not suitable for use with HFC refrigerants such as R134a or R23.

Benefits

Greater chemical resistance against reactions with the refrigerant
Better fluidity at lower temperatures which warrant a better efficiency and avoids blockage of pipes and coolers
Good dispersibility for optimal heat transfer and oil return
