TEGA to blend EU refrigerants


Technische Gase und Gasetechnik (TEGA) GmbH, a subsidiary of The Linde Group, has signed an agreement with A. S. Trust & Holdings, Inc. to blend the climate-friendly, ASHRAE-listed hydrocarbon refrigerants HCR188C/R441A and HCR188C/R443A.

TEGA, based in Wurzburg, Germany, will have exclusive blending rights within the European Union. Work is underway for the TEGA blending facility to be ETL safety certified by Intertek Germany for this production; the company expects to go into production within 30 days.

HCR188C/R441A, a substitute for R134A refrigerant, and HCR188C/R443A, a substitute for R22 refrigerant, are both patented and trademarked zero-ozone-depleting/extremely low global-warming-potential (GWP) hydrocarbon blends. Their formulations were developed over the past fifteen years by Hawaii businessman and inventor, Richard Maruya, of A.S. Trust & Holdings. HCR188C/R441A has been listed on the U.S. Federal Register for use in vending machines, household models of refrigerators, stand-alone freezers and window-air-conditioners, and commercial models of refrigerators, freezers and stand-alone refrigerated display cases. Applications have been submitted for additional uses, including motor-vehicle air-conditioning systems, refrigerated transport (refrigerated trucks and shipping containers), and residential models of heat-pumps, portable room air-conditioners and split-system air-conditioning units.
