The new Genesis screw compressor chiller range includes options for both R134a and R513A/R1234ze, aimed at helping installers and engineers manage refrigerant phase-down in larger applications.
Alongside the low-GWP options, both Genesis and eComfort ranges will continue to provide support for R410A and R134a.
Florian Beduchaud, chiller product manager at Lennox EMEA, said: "Today, consulting engineers want clear alternatives to R410A and R134a, which, due to the phase down, have become more expensive and difficult to source.
"Although R410A and R134a are not banned, many installers are keen to switch to take advantage of lower taxes and leak-testing requirements. R32, R513A and R1234ze are the best choices, and introducing these options early gives our customers the best chance to plan their transition at their own pace.''
