Description:

Shell Clavus Oils are high quality, hydrotreated naphthenic mineral oils without additives. Specific selection of the base oil gives a range of products specially suited for the efficient lubrication of refrigerator compressors. 

Applications:

• Refrigerator compressors

Shell Clavus is designed for the lubrication of compressors with ammonia (R717) as refrigerant. It can also be used when hydrocarbon (e.g. R600a) are the refrigerant. It may be used with halogenated hydrocarbon (R12,R22) if Shell Clavus G is not available. 

For all refrigeration and air-conditioning applications: domestic, commercial and industrial systems with high, moderate or low evaporation temperatures. 

• General lubrication

Apart from the application in refrigerators Shell Clavus can also be used for general lubrication at low temperatures. 

Advice on applications not covered in this leaflet may be obtained from your Shell representative.
