Natural gas compressor

Our Mobil Gargoyle Arctic SHC™ 200 Series refrigerant oils are designed for use in refrigeration compressors and heat pumps. These fully synthetic refrigeration lubricants are able to perform in severe service conditions that are beyond the capabilities of many conventional oils.

Mobil Gargoyle Arctic SHC 200 Series lubricants are recommended for refrigeration compressors operating at very high temperatures, and for systems with very low evaporator temperatures. They are suitable for use with refrigerants such as carbon dioxide and ammonia.

Mobil Gargoyle Arctic SHC™ 200 refrigerant oils can:

  • Reduce shaft seal leakage
  • Extend oil life
  • Minimize volatility and help reduce oil carryover
  • Improve machine operating efficiencies

Protects at temperatures

down to -51°C

Features and Benefits

The Mobil Gargoyle Arctic SHC brand of lubricants are recognized and appreciated for their innovation and outstanding performance.

Our work with equipment builders has helped confirm the results from our own laboratory tests showing the exceptional performance of the Mobil Gargoyle Arctic SHC 200 Series lubricants. Not least among the benefits shown in work with OEMs is the superb low temperature capability providing excellent fluidity at low temperatures, as well as the resistance to viscosity loss due to refrigerant absorption under pressure, along with providing excellent bearing film thickness and shaft sealing properties.

By its nature, the PAO base stock  used in Mobil Gargoyle Arctic SHC 200 Series oils provides exceptional thermal/oxidative resistance critical for high temperature applications. The narrow molecular weight distribution of the PAO base stocks also minimizes volatility and can help to reduce oil carryover. Mobil Gargoyle Arctic SHC 200 Series oils offer the following features and potential benefits:

Applications

Mobil Gargoyle Arctic SHC 200 Series are fully synthetic lubricants specifically designed for use in refrigeration compressors and heat pumps.

 

Application Considerations: While Mobil Gargoyle Arctic SHC 200 Series are compatible with mineral oil products, a mixture will detract from their performance.  Systems should be thoroughly flushed and cleaned when replacing a mineral product with a Mobil Gargoyle Arctic SHC 200 Series product. In the case of R22 refrigerants, guidance from the supplier of the refrigeration unit must always be sought to ensure compressor operation is suitable for efficient separation of the oil and refrigerant.

 

Typical applications are indicated below:

     •  Commercial, industrial, heat pump applications and marine refrigeration systems

     •  Commercial, industrial and residential heat pump applications

     •  Recommended for both reciprocating and rotary compressor designs

     •  Recommended for use with the following refrigerants: Ammonia and Carbon Dioxide
