ARLINGTON, Va. - The Air-Conditioning and Refrigeration Institute (ARI) recently launched its certification program for liquid-to-liquid heat exchangers. The program joins 22 other ARI-administered certification programs, and will likewise utilize the ARI certification symbol to designate product performance.

The program's goal is to provide a common method for evaluating the thermal performance of liquid-to-liquid heat exchangers and to give consumers confidence in the equipment they purchase, stated the institute.
