Compresyn HD PGE Series fluids are synergistic blends of synthetic polyglycols, pentaerythritol esters and selected additives formulated to provide superior performance and extended drain capabilities in rotary screw, rotary vane and centrifugal compressors. Formulated to provide 10,000+ hour drain intervals in rotary compressors and 24,000+ hour drain intervals in centrifugal compressors, these fluids can be run continuously for one year, eliminating fluid- and labor-related downtime costs during this time. Compresyn® HD PGE Series fluids provide outstanding sealing between the rotors and the stator. Their outstanding thermal conductivity removes the heat of compression, allowing the compressor to run cooler while lubricating the rotary and centrifugal element bearings. Compresyn HD PGE Series fluids are fully formulated synthetic compressor fluids containing no hydrocarbon-based fluids. They are highly resistant to sludge and varnish formation, and provide solvency characteristics for cutting through and dissolving varnish buildup in older machines.
