Why NH3

Natural refrigerants CO2, ammonia and hydrocarbons have been used in different HVAC & R applications for many years. With the exception of a few sectors, their market penetration has remained relatively low.

Advantages of CO2

The use of natural refrigerants is certainly not new. Way back in the last century and even the century before that, air, ammonia (NH3), carbon dioxide (CO2), propane (R290), sulphur dioxide (SO2) and other refrigerants were used.
