Refrigeration Compressor Oils

Product Description

Mobil Gargoyle Arctic SHC 200 Series

 

 

The Mobil Gargoyle Arctic SHC™ 200 Series are fully synthetic, supreme performance lubricants, specifically designed for use in refrigeration compressors and heat pumps. They are formulated from wax-free, synthesised hydrocarbon polyalphaolefin (PAO) fluids, which have outstanding resistance to thermal/oxidative degradation. With their naturally high shear stable viscosity indexes and low temperature fluidity, they are able to perform in severe service conditions that are beyond the capabilities of conventional mineral oils. Their solubility and miscibility with commonly used refrigerants is low, resulting in higher film thicknesses in the presence of refrigerants under pressure which can reduce shaft seal leakage. Their stability and low volatility characteristics eliminates the  "light end stripping" which can occur with conventional mineral oils.

Mobil Gargoyle Arctic SHC 200 Series lubricants may help reduce frictional losses and improve machine operating efficiencies.Mobil Gargoyle Arctic SHC 200 Series lubricants are recommended for the lubrication of refrigeration compressors operating at very high temperatures, and for systems with very low evaporator temperatures. They are suitable for compressor systems using refrigerants such as ammonia and carbon dioxide . Their  low miscibility with carbon dioxide , makes them commonly  recommended for screw compressors using carbon dioxide. They are compatible with all refrigerants except sulphur dioxide and have been particularly successful with systems using ammonia as the refrigerant. Mobil Gargoyle Arctic SHC 200 Series are fully miscible with conventional mineral oils. Any mixture with mineral oils may detract from the superior performance properties of the Mobil synthetic product.

Mobil Gargoyle Arctic Series

 

Gargoyle Arctic Oil 155, 300, and 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 Gargoyle Arctic oils ensures 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.

Gargoyle Arctic Oil 155, 300, and Gargoyle Arctic C Heavy are compatible with all refrigerants except sulphur dioxide. They are not recommended for use with HFC refrigerants. The moisture content of Gargoyle Arctic Oil 155, 300, and 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.

 

Applications

  • Large industrial reciprocating and rotary refrigeration compressors.
  • Industrial applications such as food freezing and cold storage plants
  • Marine refrigeration applications
  • Used primarily with ammonia refrigerant, but also used with selected halocarbons
