R456a joins R513a as possible A1-rated drop-in for automotive R134a systems

Koura is about to produce a lower global warming potential (GWP) automotive refrigerant alternative to R134a as countries like Australia drag the chain on banning imports of equipment charged with high-GWP HFCs despite having ratified a phase-down schedule under the Kigali Amendment to the Montreal Protocol.


Koura’s R456a (branded Klea 456a) is an alternative to R134a on existing mobile air-conditioning systems, of which there are hundreds of millions on the road globally.

R456a has a GWP of 626, representing a significant reduction in CO2-equivalent footprint when compared to R134a which has a GWP of 1430.
