Compressor

DESCRIPTION

Alkylbenzene synthetic oils for refrigerating compressors.

APPLICATIONS
  • LUNARIA SK is a quality refrigeration compressors lubricant using CFC or
    HCFC refrigerants. Due to their chemical nature, these oils have superior
    miscibility with fluorocarbon refrigerant such as R12, R502 and R22 and are
    thus perfectly adapted to the low temperatures.
  • LUNARIA SK is also suitable for the cylinder lubrication of heavy duty
    reciprocating air compressors (discharge temperature > 200 °C).
ADVANTAGES
  • LUNARIA SK provides high chemical stability with refrigerants, low foaming
    tendency and excellent lubrication properties.
  • LUNARIA SK has very good miscibility behaviour with refrigerants allowing a
    good oil return to the compressor (down to – 60 °C at the evaporator).

CAUTION : Deposits may clog filters when shifting from a mineral oil to a synthetic
alkylbenzene oil during initial runs.
