Mobil Gargoyle Arctic SHC™ 200 Series refrigeration oils
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 formulated from wax-free, synthesised
hydrocarbon polyalphaolefin (PAO) fluids, providing exceptional thermal and oxidative resistance critical for high temperature applications 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 offer:
- Extended service life, helping minimise downtime and maintenance costs
- Excellent anti-wear protection to reduce lacquer and deposits
- Reduced shaft seal leakage
- Improved system efficiency and optimised power consumption
It is recommended that systems should be thoroughly flushed when replacing a mineral product.

Features and Benefits
The Mobil Gargoyle Arctic SHC brand of lubricants are recognised 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:
| Features | Advantages and Potential Benefits |
|---|---|
| High oil film thickness in the presence of refrigerant | Improved compressor protection for extended compressor life as well as better shaft sealing, reduced bearing fatigue and less unscheduled downtime |
| Excellent thermal/oxidative and chemical stability | Long oil life and reduced frequency of drain intervals and routine maintenance |
|
|
Reduced lacquer and deposit formation |
| Low volatility | Viscosity remains consistent with reduced oil consumption |
| High Viscosity Index and wax-free | Excellent low temperature fluidity, no waxy deposits and improved evaporator efficiency |
| Low traction coefficient | Potential for improved system efficiency and reduced power consumption |
| Seal compatibility | Long seal life, reduced shaft seal leakage |
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
