Briton Refrigerant R717

Briton Refrigerant R717 (Ammonia)

Briton Refrigerant R717 (Ammonia) has been used in industrial applications since the 1930s and is generally acknowledged as being the most efficient refrigerant. It has a low boiling point and is favoured because it is a highly energy efficient refrigerant which also has minimal environmental impact, having zero ODP (Ozone Depletion Potential) and zero GWP (Global Warming Potential).

Briton Refrigerant R717 (Ammonia) has highest refrigerating capacity per pound of any refrigerant and a number of other excellent thermal properties that make it popular for a number of refrigeration applications in spite of its being toxic, explosive and flammable within certain conditions. Ammonia is used as refrigerant prominently in the refrigeration systems of food industry like dairies, ice creams plants, frozen food production plants, cold storage warehouses, processors of fish, poultry and meat and number of other applications.
