Mobil Gargoyle Arctic 68 NH is a high-performance refrigeration compressor oil designed specifically for the lubrication of reciprocating and screw refrigeration compressors using ammonia (NH3, R-717). It is formulated with high quality paraffinic technology, which offers excellent performance at low temperature, low evaporation rate and high thermal stability.

Low evaporation rate helps reduce oil consumption (reduced need to add oil) and limits oil dilution resulting from the formation of fractions
Low Brookfield viscosity contributes to good oil flow at low temperatures and good oil return from the evaporator
Provides surface protection for increased equipment life and lower repair costs
Has a High Viscosity Index for good compressor lubrication over wide operating temperature ranges
Compatibility with the refrigerant contributes to oil separator efficiency (very low miscibility with NH3)

Large industrial reciprocating and screw refrigeration compressors used in the food industry for food preparation and freezing
Industrial usage areas such as food freezing and cold storage facilities
Marine refrigeration applications
