SF-580 | SYNTHETIC COMPRESSOR OILS

GENERAL DESCRIPTION:

SELCO SF-580 is a high-performance synthetic compressor refrigerant oil based in a proprietary PAG (polyoxyalkylene glycol) + additive blend. The product exhibits excellent extreme temperature properties coupled closely with outstanding oxidation resistance. Currently available lubricants often compromise on compressor requirements, for example reciprocating units using automotive crankcase oils formulated to MIL specifications can suffer from heavy carbon and ash deposits on valves, SELCO products, on the other hand, are formulated solely for compressors.

RECOMMENDED USAGE:

SELCO SF-580 is recommended for use with various gases, including liquefied petroleum gases such as propane and butane, as well as liquefied natural gases like methane and ethane. It is also suitable for hydrocarbon chemical gases such as ethylene, propylene, and butylene, along with chemical gases like ammonia, vinyl chloride, and butadiene.
