Milestones in the Development of HCR188C and It's Derivatives
Finalization of SNAP rulemaking on climate-friendly refrigerants. The EPA Administration signed a rule on 27 February 2015, listing HCR188C1/R441A as acceptable, conditionally, for use as a refrigerant in retail food refrigeration (stand-alone units), in vending machines, and in room air conditioners. This ruling was published in the U.S. Federal Register at the end of March 2015 . Reference: view EPA document
04 September 2012 - United States Environmental Protection Agency confirmed Completeness Determination for SNAP Submission for Use of R-441A in Retail Food Refrigeration, ie commercial stand alone refrigerators, freezers and display cases, including coolers and beverage refrigerators.

Kaneohe, Hawaii – July 10, 2012 – Green natural refrigerants continue to make the news, but their application to commercial and residential products has waited for the cooling industry’s equipment designs to keep pace. Now A.S Trust & Holdings, developer of the climate-friendly hydrocarbon refrigerants R441A (HCR188C1), a substitute for R134A and R443A (HCR188C2), a substitute for R22, has moved forward by designing a safety valve to provide a safe operating system when dealing with flammable and/or toxic refrigerants. (See final spec sheet for Safety Valve SV001A under "Guidelines For Usage").

December 28th, 2008 - EPA issues Final Completeness Determination under the Significant New Alternatives Policy (SNAP) program. HCR188C approved for sale in the United States as a replacement for CFC-12 (R12) coolant fluid in household refrigeration and air conditioning units.
April 2008 – Richard Maruya honored with the 2008 Environmental Award for Outstanding Achievement from the EPA’s Region IX office in recognition of his efforts and commitment to protecting the environment through the development of HCR188C. The U.S. Congress notes his “innovative work developing the Hydro Carbon Refrigerant 188C [as] an environmentally safe and efficient alternative to the traditional hydrocarbon-based products harmful to the ozone layer”.
February 2007, the Intertek Company in Cortland, NY commenced testing HCR188C (in a plant refrigerator) and to date (February 2011) is completely satisfied with its operation. In addition, A.S. Trust & Holdings has been running the formulation in the air-conditioning system of a 1996 Toyota T100 truck for over six years (65,000 miles) without having to recharge the system.
