Alfa Laval has received a Certificate of Performance Excellence from AHRI (Air-Conditioning, Heating and Refrigeration Institute, formerly ARI) in recognition of three consecutive years of a 100% success rate in annual performance testing for plate heat exchangers. Alfa Laval has had a perfect test record since initial testing took place in 2004. The ARI Standard 400 certification program includes independent third-party performance tests on heat transfer and pressure drop to ensure that each manufacturer measures performance in the same way. www.alfalaval.com
