Refrigerants
Tool kit to ease
transition away
from R404A DANFOSS HAS COMPILED an inventory
of tools together with a product portfolio to help ease the transition from R404A to alter- native refrigerants.
With a Global Warming Potential (GWP) of 3992, R404A is among the most popular refriger- ants covered by the January 2020 F-Gas ban in Europe and phase down in the frame of the Mon- treal Protocol.
The solutions announced by Danfoss include components for use with R404A nonflammable al- ternatives like R448A, R449A, R452A, R513A, and R134a – along with free digital tools to help HVACR professionals make the best possible choice.
Danfoss Cooling marketing director for refrig- eration, Thierry Raoul, said the transition pro- cess 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 re- frigerant can be used for servicing, and the pha- seout quotas have seen prices fluctuate signifi- cantly,” Raoul said.
“But we’re well aware of the scale of the chal- lenge. That’s why we invest thousands of hours in qualification processes and product upgrades to ensure high quality and reliability in the field. And reliability is what shop owners will remem- ber at the end.”
Raoul said Danfoss has the broadest possi- ble toolkit of components and advice to aid the transition.
“In fact, our Coolselector 2 tool has been de- signed to help you select the best components
for your low-GWP refrigerants – including the relevant log(p)-h diagrams or pipe sizing. Put simply, we’re ready when you are,” he said.
Danfoss is helping the move to lower-GWP re- frigerants in several ways:
• Qualified components – including EVR v2 so-
lenoid valves; TU, T2, TD1, TE 5-55 thermo- static expansion valves, filter driers DML, GBC ball valves, NRV check valves and SGP
“THE TRANSITION PROCESS IS WELL UNDERWAY....WE’RE WELL AWARE OF THE SCALE OF THE CHALLENGE.”

sight glasses, MLZ and LLZ scroll, VLZ invert- er scroll as well as MTZ and NTZ reciprocat- ing compressors, and Optyma indoor and out- door condensing units.
• Multi-refrigerant capability – with several pos- sible replacements for R404A, having one com- ponent qualified for several refrigerants keeps your options open, and your inventory lean.
• Free digital tools and apps such as the Coolselector 2, refrigerant Slider and low- GWP. Meanwhile, infographics make it easy to see the impact on system and component performance.
