Syncon® Refrigeration Oil


Phillips 66® Syncon Refrigeration Oil is a premium quality, synthetic lubricant developed for use in rotary screw compressors in refrigeration systems using ammonia, methyl chloride, or carbon dioxide. It has better oxidation resistance than conventional paraffinic and naphthenic-based refrigeration compressor oils, resulting in less buildup of varnish and sludge deposits and longer service life. It is registered by NSF International as an H1 lubricant for use where incidental food contact may occur.
