POLYOL ESTER LUBRICANT THE CFC REPORT - LEADING THE WAY INTO A NEW AGE After exhaustive research and testing, Copeland has determined that PolyolEster (POE) lubricants provide the best combination of characteristics for use with the new generation of chlorine-free refrigerant. In addition to providing superior lubrication. POE has other advantages which increase its attractiveness for use in refrigeration. Polyol Ester is a synthetic lubricant used primarily for jet engine lubrication. It is manufactured by numerous companies and there are various types and grades available. Therefore, it is important to recognize that all POE's are not the same. Since POE is synthetic, it has better resistance to high temperature degradation than refrigeration mineral oils. POE is also made from more expensive base stocks making it significantly more expensive than other refrigeration oils. Furthermore, POE is compatible with common refrigerant and mineral oil. Therefore, a compressor containing the oil can be installed in a system containing HCFC's or HFC's. In short, POE provides significant flexibility in the face of changes brought on by the CFC issue. HFC refrigerant require the use of POE for all Copeland compressors. This is necessary for two specific reasons. First, mineral oils are not readily miscible in HFC's. When using HFC's conventional oils will not return to the compressor. Secondly, the chlorine contained in CFCs and HCFCs aids in the lubricity of mineral oil. One drawback from using POE is that they absorb moisture from the air at a much greater rate than do mineral oils. As a result, they must be handled and Polyol Ester Lubricant 21 packaged with much more care than conventional oils. Copeland has not tested all types of compressors or all combinations of refrigerant and con-Industry knowledge of POE must rapidly increase in order to maintain and improve expected reliability. After conducting extensive tests for both compressor durability and reliability on more than 40 refrigerant/oil combinations, Copeland identified Mobil Oil Corporation as our preferred U.S. supplier of polyol ester oil in terms of both the oil itself and Mobil's ability to package and deliver the oil with acceptable low moisture levels. Because of its technical superiority. Copeland has approved Mobil's EAL Artic 22 CC polyol ester oil for use in our compressors. To serve our customers, Copeland will distribute E A L Artic 22 CC to the after market through Copeland's network of 800 authorized wholesalers. The lubricant will be charged into our new production compressors whenever a polyol ester is specified. C u r r e n t l y, certain approved compressor models sold to OEMs are available with this oil installed during manufacture. Refrigeration service compressors charged with POE will be supplied in the near future.
