ComStar to Offer Silekan Compressors Using New "Green" Energy-Saving Hydrocarbon Refrigerant R441a

Share Article

ComStar, a producer of environmentally safe chemical products for the HVACR, Indoor Air Quality and plumbing industries, will offer compressors that run the new energy-saving blended-hydrocarbon refrigerant, R441a. These compressors, marketed under the Silekan brand name, will allow appliances and air-conditioners to take advantage of R441a's Zero ratings for Global Warming Potential and Ozone Depletion Potential.

It is inevitable that hydrocarbon refrigerants are on the verge of coming into the U.S. market. ComStar has entered into agreements with Mr. Richard Maruya, the creator of R441a, to manufacture and distribute his blended hydrocarbon refrigerant.

ComStar International Inc., a leader in the development and marketing of industrial strength, environmentally safe chemical products for the HVACR, Indoor Air Quality and plumbing industries, and its China JV company, will begin offering appliance and air conditioning compressors in the U.S. and overseas markets for the patented and U.S. EPA-approved blended-hydrocarbon refrigerant, R441a. The compressors are made in China by Hangzhou Maidi Heating & Refrigerating Equipment Co. Ltd under the Silekan brand name. Each compressor will be ETL approved to OEM specifications. Residential refrigerator Energy Star testing with R441a will take place this March. ComStar is licensed as the exclusive U.S. manufacturer and distributor of R441a by A.S Trust & Holding, Inc. and Richard Maruya, the refrigerant inventor.

Domestic refrigerator energy-draw tests with R441a have shown a 48% decrease in power consumption when compared to refrigerators operating with 134a. R441a is an extremely energy-efficient blended-hydrocarbon refrigerant that operates on approximately 25% of what a normal charge of 134a would be in an appliance or automotive cooling system and at 40% of an R22-charged appliance. Electrical power consumption tests in air conditioners and other appliances have shown similar energy savings. As an added benefit, R441a has zero global warming potential and is non-ozone depleting.

Steven P. Mella, ComStar’s CEO, said, “While ComStar offers the RS series of HFC-alternative refrigerants for in-place R22 systems, it is inevitable that hydrocarbon refrigerants are on the verge of coming into the U.S. market. As a result, ComStar has entered into agreements with Mr. Richard Maruya, the creator of R441a, to manufacture and distribute his blended-hydrocarbon refrigerant." R441a, also known as HCR188C, is the first hydrocarbon refrigerant to be approved for sale in the United States by the U.S. Environmental Protection Agency. R441a is EPA SNAP-approved for use in household refrigerators, freezers and window air-conditioners. It has the ASHRAE certification as being considered non-toxic. R441a operates with mineral oil and can be used in appliances and automotive cooling systems designed for 134a and R22. While R441a is flammable, the very small amount of this climate-friendly refrigerant required in appliances or automotive cooling systems makes the risk assessment a non-factor. A.S.Trust & Holding also has a patent on a Refrigerant Safety Service Port Valve that could be used on larger systems. This unique valve was invented by Richard Maruya and George Whitmyre and operates by shutting down the system when there is a drop in operating pressure.

ComStar is now producing limited quantities of R441a at its certified refrigerant production facility in south Texas.

R441a will be available through HVACR and appliance wholesalers nationwide. Visit our website at http://www.comstarproducts.com for a wholesaler near you. Visit http://www.hcr188c.com to learn more about R441a (HCR188C).
