Arlington, VA – The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) has published a white paper, Reports of R-134a Contaminated with R-40 and Other Refrigerants, to assist contractors and others in the industry in identifying and avoiding counterfeit refrigerants.
“Members of the Chemicals and Refrigerant Reclaimers and Mobile Refrigeration product sections of AHRI are taking these claims very seriously,” said AHRI President and CEO Stephen Yurek. “Refrigerants contaminated with R-40 pose the risk of explosion, so we must make every effort to detect its presence and ensure that its concentration is below the maximum level recommended by AHRI Standard 700.”
Recently, R134a, R-22, R-404a, and R-410a have been found to be counterfeit and in some instances badly contaminated. In order to avoid counterfeit refrigerants, the white paper recommends knowing your supplier, properly verifying refrigerant prior to use or servicing equipment, and properly labeling and isolating contaminated refrigeration systems. The white paper also offers methods to detect contaminants, and steps for remediation.
