The Castrol range of mineral based refrigeration oils is available as two grades of specially selected oils, highly refined to provide chemical and thermal stability.   

Their low wax forming tendencies insure low pour points.

A range of different types and brand of refrigeration oils is available on request from the Wilhelmsen Ships Service Spare Part Centres.

The compressor is the heart of any refrigeration system and it is recommended that the system oil is changed or tested at regular intervals.

This could be on an annual basis or more frequently if the oil becomes dark or cloudy.

A good rule is to renew the oil if a major service or repair has been carried out on the compressor or the system.

Icematic 299 is generally used for high temperature applications like A/C systems.  Compatible with HCFC refrigerants like R-22 and some HFC refrigerants like Unicool R-417A.
