Alfa Laval is a leading global provider of specialized products and engineering solutions based on its key technologies of heat transfer, separation and fluid handling. The district cooling system from Alfa Laval offers operating flexibility, since each building can use as much or as little cooling as needed, without worrying about chiller size or capacity – and the system produces no noise or vibrations. Hotels, shopping centers, industrial buildings, office buildings, residential buildings, sports centers and hospitals are examples of facilities that use district cooling. Alfa Laval can also aid in the cleaning of the heat exchangers. The AlfaQ™ gasketed plate heat exchanger range is certified to AHRI 400. The Air Conditioning, Heating and Refrigeration Institute (AHRI) Standard 400 certification is an independent, third-party verification of thermal performance. Through its certification program and standards, AHRI strives to help customers save energy, improve their productivity and help to ensure a better environment.
