ARI launches liquid-to-liquid heat exchanger certification program.

ARLINGTON, Va. - The Air-Conditioning and Refrigeration Institute has launched a certification program for liquid-to-liquid heat exchangers. The new program joins 22 other ARI-administered certification programs.

The goal of the new certification program is to provide a common method for evaluating the products' thermal performance.

"To allow buyers and users to make apples-to-apples comparison for a specific application, products certified under ARI Standard 400 should be specified," said Al Valentino, a product manager with heat exchanger maker Alfa-Laval. "Doing so provides confidence that all heat exchangers are rated in a uniform manner."
