Gargoyle Arctic SHC 200 SeriesRefrigeration Oils

Product DescriptionGargoyle Arctic SHC 200 Series are fully synthetic, supreme performance lubricants, specifically designed foruse in refrigeration compressors and heat pumps. They are formulated from wax-free, synthesised hydrocarbonpolyalphaolefin (PAO) fluids, which have outstanding resistance to thermal/oxidative degradation. With theirnaturally high shear stable viscosity index and low temperature fluidity, they are able to perform in severe serviceconditions that are beyond the capabilities of conventional mineral oils. Their solubility and miscibility withrefrigerants is low, resulting in higher film thickness in the presence of refrigerants under pressure and reducedshaft seal leakage. Their stability and low volatility eliminates "light end stripping" which can occur withconventional mineral oils. Gargoyle Arctic SHC 200 Series lubricants help reduce frictional losses and improvemachine operating efficiency.

Gargoyle Arctic SHC 200 Series lubricants are recommended for the lubrication of refrigeration compressorsoperating at very high temperatures, and for systems with very low evaporator temperatures. They are suitablefor compressor systems using refrigerants such as ammonia and carbon dioxide; they have enjoyed excellentexperience with CFC refrigerants such as R-12. They are compatible with all refrigerants except sulphur dioxideand have been particularly successful with systems using ammonia as the refrigerant. Gargoyle Arctic SHC 200Series are fully miscible with conventional mineral oils but admixture may detract from the superior performanceproperties of the Mobil synthetic product.

Features and BenefitsThe Gargoyle Arctic SHC brand of lubricants are recognised and appreciated around the world for their innovationand outstanding performance. These molecular design PAO synthetic products, pioneered by our researchscientists, symbolise the continuing commitment to using advanced technology to provide outstanding lubricantproducts.

Our work with equipment builders has helped confirm the results from our own laboratory tests showing theexceptional performance of the Gargoyle Arctic SHC 200 Series lubricants. Not least among the benefits shownin work with OEMs is the superb low temperature capability providing excellent fluidity at low temperatures, aswell as the resistance to viscosity loss due to refrigerant absorption under pressure providing excellent bearingfilm thicknes and shaft sealing properties.

By its nature, the PAO base oil used in Gargoyle Arctic SHC 200 Series oils provides exceptional thermal/oxidativeresistance critical for high temperature applications. The narrow molecular weight distribution of the PAO basestocks also minimizes volatility and reduces oil carryover. Gargoyle Arctic SHC 200 Series oils offer the followingfeatures and potential benefits:

Advantages and Potential BenefitsFeaturesImproved compressor antiwear protection for extendedcompressor life as well as better shaft sealing, reducedbearing fatigue and less unscheduled downtime

High oil film thickness in the presence of refrigerant

ApplicationsGargoyle Arctic SHC 200 Series are fully synthetic lubricants specifically designed for use in refrigerationcompressors and heat pumps.

Application Considerations: While Gargoyle Arctic SHC 200 Series are compatible with mineral oil products, amixture will detract from their performance. Systems should be thoroughly flushed and cleaned when replacinga mineral product with a Gargoyle Arctic SHC 200 Series product. In the case of R22 refrigerants, guidancefrom the supplier of the refrigeration unit must always be sought to ensure installation operation is suitable forefficient 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
