          Why R410A?



          R410A is a lower GWP refrigerant (less than 2500) than   Contributes to reducing installation cost and refrigerant charge
          R404A and is fully F-gas compliant. It’s future proof: it   R410A is a high pressure refrigerant which for the same swept volume can deliver
          can be used even after 2030!             much more refrigeration capacity than standard mid pressure and low pressure
                                                   refrigerants.

              › an easy to handle, common used refrigerant in the air conditioning world, therefore it is easy to find an installer which can work with
            this refrigerant, compared to CO , Ammonia and Propane.
                                    2
              › an A1 refrigerant, therefore no special safety measurements are required.
