What are the main advantages of ammonia as a refrigerant?
Ammonia is one of the most climate-friendly and cost-efficient refrigerants to heat, cool and freeze. It is also:
Non-ozone depleting: Ozone Depletion Potential = 0
Non-climate damaging: Global Warming Potential = 0
Abundant: part of natural cycles, essential for many biological processes
Safe: with proper handling
Energy-efficient: usually better energy efficiency than systems using chemical gases
Cost-efficient: low refrigerant purchase price, low system running costs
