ComStar International Inc., a New York based company, is a leader in developing, manufacturing and marketing environmentally safe, industrial strength chemical products. Trade professionals in the heating, ventilation, air conditioning and refrigeration (HVAC&R) have used ComStar products for over forty years. ComStar distributes more than 300 specialty chemical products specifically designed to save energy, protect the environment and provide user safety. Outside the U.S., ComStar has operations in China, Japan, the UK and Canada.

While ComStar offers the RS series of HFC alternative refrigerants for in-place R22 systems, and as hydrocarbon refrigerants are on the verge of coming into the U.S. market, ComStar has entered into agreements with Mr. Richard Maruya of A.S. Trust & Holdings, the inventor of R441A (HCR188C), to manufacture and distribute his blended hydrocarbon refrigerant. R441A is one of the first hydrocarbon refrigerants that is soon expected to be approved for sale in the United States by the U.S. Environmental Protection Agency under the Significant New Alternative Policy (SNAP) for use in household refrigerators and freezers.
