Rotary screw compressor lubricants
Ultrachem Coolant and Coolant 32 are developed from a unique premium blend of polyalkylene glycol (PAG) and esters which together form an exceptional coolant and act to reduce oxidation and deposit formation. They offer excellent heat transfer properties, long life, high flash points, low evaporation, low volatility, and excellent hydrolytic stability. They do not form varnish deposits like petroleum or PAO oils. Ultrachem Coolant and Coolant 32 are a less expensive alternative to our Ultrachem Coolant PE and Coolant 32 PE. We recommend the PE versions for applications involving high humidity, heat or other demanding conditions that may result in shorter life.
Typical Industrial Applications:
Rotary Screw CompressorsPerformance Benefits: 100% synthetic, Wide temperature range, Extended oil change intervals, Eliminates deposit formation, High flash points mean reduced fire hazards, Waste disposal is minimized due to longer life, Cost effective, Eliminates seasonal oil changes.
