Multi-refrigerant, A2L-ready compressors…

With increasingly strict requirements to lower the Global Warming Potential (GWP) level of refrigeration systems, cooling professionals have an opportunity to start the green transition today by switching to A2L refrigerants with a GWP level below 150. And because change takes time, Danfoss will guide you through the refrigerant transition with frontline knowledge of growing requirements – and provide the products that are A2L-compliant and safe to install. The transition to ultra-low GWP refrigerants is just on the horizon, with the next high-GWP HFC phase-down step coming at the end of 2021 with a 55% reduction versus the 2015 baseline.

A2L refrigerants offer cooling professionals a cost-effective option that maintains a conventional system design while significantly minimizing the GWP level. In practice, a refrigerant like R1234yf offers a 99% reduction in GWP compared with A1 refrigerant R134a—achieving that result without any added complexity.

Contextually, Danfoss’ comprehensive range of A2L-ready condensing units, compressors and components ensure that the company is prepared for the green transition. Detailing on the developments, Rogerio Salhab Federici, Head of System Solutions at Danfoss Climate Solutions, said, “A2L refrigerants are environmentally-friendly solutions that meet increasingly tough restrictions—but do require specific safety testing and design due to their mild flammability. The new Optyma condensing units have been ignition-proof tested in independent laboratories and designed with risk-mitigation precautions, such as a sealed electrical box, holes and louvers to ensure the refrigerant’s dilution – giving installers peace of mind.”
