Natural refrigerants

Around the world, in many places as a result of national or regional legislation, there is a move away from traditional refrigerants in favor of refrigerants with lower global warming potential (GWP). In particular, there is a rapidly increasing market for natural refrigerants such as ammonia, CO2 and hydrocarbons.

While this is hardly the first time the refrigerants market has seen big changes, the current shift differs in the number of available options. Historically, the possibility of a one-to-one switch has allowed for a relatively easy process throughout the entire supply chain, with direct components making quick and simple retrofits possible. Today the situation is very different, and the “right” choice of refrigerant will very much depend on the equipment and application in question.

Alfa Laval is home to some of the market’s leading experts on the subject of natural refrigerants. Their expertise has allowed us to develop a wide range of heat exchanger solutions specially designed to handle the unique demands of working with challenging and sometimes dangerous substances like carbon dioxide (R744), ammonia (R717) and propane (R290). Contact us today, and we can work with you to find the optimal technology for your specific needs.

Our solutions

AlfaNova fusion-bonded plate heat exchangers

Built with our unique fusion bonding method, AlfaNova's 100% stainless steel design can withstand more extreme temperatures and pressures with greater fatigue resistance. It therefore offers a highly compact and efficient solution for cooling of very clean, sensitive liquids and when taking advantage of the low-GWP potential of ammonia.

Industrial semi-welded plate heat exchangers

Our compact semi-welded heat exchangers enable even higher efficiency and reliability when using ammonia as a low-GWP refrigerant in industrial refrigeration applications. Alfa Laval semi-welded heat exchangers are also ideal in cascade systems operating with CO2 as a secondary medium for freezing applications, reducing ammonia charge while preventing the risk of cross-contamination with their proven RefTight™ sealing system.
