What type of heat exchanger is best for natural and synthetic low-GWP refrigerants?
Different types of refrigerants have different properties and therefore require different heat exchanger designs. The optimal choice of heat exchanger may also be influenced by the specific application or duty in question. Alfa Laval is home to some of the leading experts in the use of synthetic and natural refrigerants with low global warming potential (GWP). Today we offer a wide portfolio of heat exchangers specifically engineered to meet the unique demands of working with hydrocarbons, CO2 and ammonia. In the knowledge bank section on Alfa Laval Heating and Cooling Hub, you will find videos explaining challenges and opportunities created by low-GWP refrigerants, as well as a detailed white paper available for download.
What does AHRI mean, and is it important?
AHRI stands for the Air-Conditioning, Heating, and Refrigeration Institute. AHRI offers the market’s only third-party certification to ensure that heating, ventilation, air conditioning, refrigeration, and water heating products perform according to manufacturers’ published claims. Alfa Laval has AHRI certification for gasketed plate heat exchangers, brazed plate heat exchangers and fusion-bonded plate heat exchangers. You can read more about AHRI here.
