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 index 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 refrigerants is low, resulting in higher film thickness in the presence of refrigerants under pressure and reduced shaft seal leakage. Their stability and low volatility eliminates "light end stripping" which can occur with conventional mineral oils. Gargoyle Arctic SHC 200 Series lubricants help reduce frictional losses and improve machine operating efficiency.

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; they have enjoyed excellent experience with CFC refrigerants such as R-12. They are compatible with all refrigerants except sulphur dioxide and have been particularly successful with systems using ammonia as the refrigerant. Gargoyle Arctic SHC 200 Series are fully miscible with conventional mineral oils but admixture may detract from the superior performance properties of the Mobil synthetic product.

The Gargoyle Arctic SHC brand of lubricants are recognised and appreciated around the world for their innovation and outstanding performance. These molecular design PAO synthetic products, pioneered by our research scientists, symbolise the continuing commitment to using advanced technology to provide outstanding lubricant products.

Our work with equipment builders has helped confirm the results from our own laboratory tests showing the exceptional performance of the 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 providing excellent bearing film thicknes and shaft sealing properties. 

By its nature, the PAO base oil used in 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 reduces oil carryover. 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 antiwear 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 drain intervals and less routine maintenance
	Reduced lacquer and deposit formation for longer filter life and reduced shaft seal leakage
Low volatility	Avoids viscosity build-up, 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

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

Application Considerations: While 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 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 installation 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
