ZEROL® alkylbenzene oils have several advantages of mineral oils in applications with R22, including better low temperature miscibility, and superior thermal and oxidative stability. Quality is also more consistent because ZEROL® is synthetically derived. Also, ZEROL® is the oil of choice for many of the new service blends designed to replace R12 and R502. These blends include MP39, HP80, and HP81.

New studies are underway that show that ZEROL® alkylbenzene oil can be used with HFC refrigerants such as R134a, R407C, and R410A in specific applications. These applications include household refrigerators, window air conditioning units, and small split systems. Major advantages of using ZEROL® alkylbenzene oil instead of polyolester oil in these HFC systems include significant cost saving in both oil and in handling procedures, and also superior lubrication in certain systems.
