Ultrachem has developed a new line of high-performance synthetic lubricants – the Chemlube Plus Series – designed to be used in a wide variety of rotary screw and rotary vane compressors. True universal lubricants, the series is fully compatible with most OEM Rotary Screw compressor oils and can be used to top off and replace existing fluids. The lubricants are made with a very thermally and oxidatively stable polyol ester (POE) blend. These oils were designed to take advantage of superior lubricating properties inherent in polyol esters, and yet be economical, by combining them with less expensive synthetics. These fully synthetic premium lubricants are formulated to form less varnish under high temperature applications and to be more resistant to acidic intake air than the polyalkylene glycol (PAG) coolants. Under normal operating conditions users can expect to obtain up to 11,000 hours of lubricant service life in rotary screw compressors. The line is available in ISO grades 32, 46 and 68.
