Ammonia in industrial refrigeration

State-of-the-art components for ammonia refrigeration

Ammonia is the most trusted refrigerant right from the 19th century. All those who are involved in food preservation and industrial process plants know ammonia as refrigerant of choice due to its unmatched thermodynamic properties. You can read more about this and the many other benefits when using ammonia via the link "Why ammonia in industrial refrigeration".

Environmental concerns and new F-gas regulation are forcing scientists and refrigeration technicians to take a serious look at natural refrigerants like air, water, ammonia, carbon dioxide and others as a long-term alternative for industrial refrigeration. Anyone involved in food preservation and industrial process plants already know ammonia as the refrigerant of choice due to its unmatched thermodynamic properties. 

Having passed the test of time over more than a century as one of the best choices, ammonia is now receiving attention in areas of application where it was unthinkable earlier. Danfoss is a leader in ammonia refrigeration components, including manual, mechanic and electric valves. We are constantly working on developing components that enable safe and energy-efficient application of ammonia refrigeration.
