Danfoss lights path away from R404A


Danfoss has compiled an inventory of tools together with product portfolio to help ease the transition from R404A to alternative refrigerants.

With a GWP of 3992, R404A is among the most popular refrigerants covered by the January 2020 F-Gas ban in Europe and phase down in the frame of the Montreal Protocol.

The solutions announced by Danfoss include components for use with lower GWP, nonflammable R404A alternatives like R448A, R449A, R452A, R513A, and R134a – along with free digital tools to help engineers make the best possible choice. Other refrigerants are being qualified.

Thierry Raoul, marketing director refrigeration, Danfoss Cooling said: “The process is well underway. From the beginning of next year, R404A can no longer be used in any new refrigeration or cooling equipment in Europe. Only recycled refrigerant can be used for servicing, and the phaseout quotas have seen prices fluctuate significantly.

Danfoss says it is well aware of the scale of the challenge and has broad range of components and in-depth advice to aid the transition.

“In fact, our Coolselector2 tool has been designed to help you select the best components for your low-GWP refrigerants – including the relevant log(p)-h diagrams or pipe sizing,” he said.
