Solest 220 is a formulated ISO VG220 synthetic polyol ester (POE) lubricant designed for commercial and industrial refrigeration and air conditioning compressors with over 25 years service in the field. Designed to maximize lubrication in HFC systems, Solest 220 provides superior bearing protection with greater film strength than standard HFC lubricants. This product provides effective wear protection for steel and aluminium surfaces for increased system life and improved efficiency. Solest lubricants are designed for standard factory fill of air conditioning and industrial refrigeration equipment, as well as for OEM retrofitting operations. CPI laboratory studies and OEM compressor bench tests have afforded a product line specifically designed to meet key system needs. Solest lubricants are not hazardous under 29 CFR 1910.1200. They provide improved properties over conventional mineral oils in all aspects, including viscosity index, flash and fire points and pour point. Applications and Compressor Type HFC, HCFC, HFO Refrigeration Reciprocating, Screw, Centrifugal Compressors Features and Benefits Thermally stable Longer system life Improved oil management Efficiency gains Corrosion protection Enhanced system reliability and reduced down-time Excellent bearing lubrication Longer compressor Life Optimized System performance Reduced operating costs Environmentally friendly Biodegradable Excellent lubricity Increased efficiency, reduced cost of operation Outstanding Miscibility The performance of an HFC system is optimized when the lubricant and refrigerant mix to form a single, clear phase. Miscibility lowers the viscosity of the lubricant carried through the system, so the lubricant can more efficiently return to the compressor. Mineral oils are not miscible with HFCs whereas Solest 220, as a polyol ester has a controlled level of miscibility with HFC gases. Excellent Thermal Stability Sealed tube results (ASHRAE 97) indicate that Soles 220 provides excellent stability in the presence of HFC refrigerants. In addition to outstanding stability, this lubricant shows no adverse effects to metals and other materials of construction.
