Mobil Gargoyle Arctic Oil SHC NH 68 is a fully synthetic lubricant that is specifically designed to lubricate refrigeration compressors in high performance plants using ammonia as the refrigerant. It is formulated with wax-free, synthesized hydrocarbons of polyalphaolefin (PAO) and synthetic Alkylbenzene base oils, which have demonstrated outstanding resistance to thermal/oxidative degradation. Even in the worst operating conditions, Mobil Gargoyle Arctic Oil SHC NH 68 will reduce sludge and deposit formation, hence avoiding or minimizing valve or filter plugging. Features and Benefits: Fully synthetic Resistant to thermal/oxidative degradation Reduces sludge and deposit formation Compatible with mineral lubricants Recommended for use in screw or reciprocating refrigeration compressors in plants using ammonia as the refrigerant Applications: Screw or reciprocating refrigeration compressors Plants using ammonia as the refrigerant Benefits to the User: Increased equipment reliability
