Mobil Gargoyle™ Arctic Oil 155, 300, and Mobil Gargoyle Arctic C Heavy
Refrigeration Oils
Product Description
Mobil Gargoyle™ Arctic Oil 155, 300, and
Mobil Gargoyle™ Arctic C Heavy products are high performance naphthenic mineral
oils primarily intended for use in refrigeration compressors. They have low
pour points and excellent fluidity at very low temperatures by virtue of being
almost wax-free. Consequently, use of these Mobil Gargoyle Arctic oils helps to
ensure that evaporator tubes are kept clean to improve heat transfer and to
reduce downtime for maintenance. They have good chemical stability and are
suitable both for cylinder and bearing lubrication.
Mobil Gargoyle Arctic Oil 155, 300, and Mobil Gargoyle Arctic C Heavy are
compatible with most refrigerants except sulphur dioxide. They are not
recommended for use with HFC refrigerants. The moisture content of Mobil
Gargoyle Arctic Oil 155, 300, and Mobil Gargoyle Arctic C Heavy oils is very
low when the oils are packaged. Every precaution should be taken to keep the
oils dry to avoid the formation of ice in expansion valves, and to limit the
risks of oil degradation, copper plating, etc.
