Capella® HFC is a premium-grade, fully synthetic oil for the lubrication of compressors used in refrigeration and air conditioning systems. Capella HFC is blended exclusively with specially selected polyolesters. It has a high viscosity index ensuring a good lubricity over a wide temperature range.
Recommended Uses
Capella HFC lubricants have been developed in cooperation with major refrigerant compressor manufacturers worldwide, specifically for use with chlorine-free hydrofluorocarbon (HFC) refrigerants, such as R134a, R404a, R410a or R507, etc. The product series are especially suited for the first-fill and retrofit lubrication of refrigeration compressors in provision and industrial refrigeration plants, as well as in air-conditioning systems and heat pump equipment.
Capella HFC grades are not recommended for use in ammonia refrigerating systems, where Capella WF or Capella A are recommended instead.
Note: Capella HFC lubricants readily absorb moisture from the ambient air, which can cause system performance problems. Capella HFC packages should be kept sealed until time of use and should not be reused once opened.
Performance Benefits
1. Efficient, Trouble-free Operation
Exhibits excellent oil-refrigerant miscibility properties with HFC-refrigerants over a wide range of operating temperatures, which helps ensure adequate lubrication of the compressor bearings and to facilitate oil return from the refrigeration system.
2. Minimum Downtime
Provides excellent thermal and chemical stability in the presence of hydrofluorocarbon (HFC) refrigerants. Demonstrated excellent compressor cleanliness with absence of any copper transfer in numerous compressor tests.
3. Lower Maintenance Costs
High resistance to oxidation, even at high operating temperatures, which helps guarantee a long service life. Provides excellent lubricity, even in the presence of refrigerants.
