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
