Shell Clavus Oil G
Refrigerator Compressor Lubricant
Shell Clavus Oils G are high quality, hydrotreated naphthenic mineral oils without additives. Specific selection of the base oils and advanced refining techniques give a range of products specially suited for the efficient lubrication of refrigeration compressors.

Mineral oil for refrigeration compressors.

Shell Clavus G has been formulated in collaboration with several major refrigerating equipment manufacturers for the lubrification of high performance refrigeration and air conditioning systems, where requirements are more and more severe:

- low temperature at the evaporator's level

- high temperature at the compressor's level

using more diverse refrigerants like ammonia or halogenated hydrocarbons (Fréon).

Applications

• Refrigerator compressors: Shell Clavus G is designed for the lubrication of compressors using halogenated hydrocarbons as the refrigerant (R12, R22). It is also suitable for use with hydrocarbon refrigerants (e.g. R600a). For all refrigeration and air-conditioning applications: domestic, commercial and industrial systems with high, moderate or low evaporation temperatures.
• Ammonia as refrigerant: Clavus G should not be used in ammonia systems with low evaporation temperatures when it cannot be guaranteed that the refrigerant system is airtight.

Advice on applications not covered in this leaflet may be obtained from Gannon Oils Ltd.
