McQuay B is a synthetic polyol ester (POE) lubricant designed specifically for refrigeration and air conditioning compressors using sub-C refrigerants. The product provides effective anti-wear protection for steel and aluminum surfaces, can extend system life and improve operating efficiency, and is suitable for initial and subsequent additions. Low temperature properties and excellent chemical and thermal stability give McQuay B a wide operating temperature range.
