Koura Klea wins Refrigeration Innovation of the Year at the 2022 Cooling Industry Awards.
LONDON, September 23, 2022 – Orbia’s Fluorinated Solutions business Koura has won the coveted award of Refrigeration Innovation of the Year at the 2022 Cooling Industry Awards.
At an awards ceremony last night (September 22) at London’s Grosvenor House Ballroom, Koura Klea® 473A was named the winning innovation from a shortlist of five with judges praising the refrigerant’s performance and sustainable industry applications.
Klea 473A is designed as a non-flammable refrigerant to achieve high performance with a significantly lower global warming potential (GWP) than existing refrigerants, R-23 or R-508B, in ultra-low temperature cooling applications such as high value cold chain, vaccine storage, climate test chambers, transportation, and other medical uses. This refrigerant has a unique combination of high capacity and energy efficiency coupled with low temperature glide as compared to other refrigerants developed as non-flammable alternatives for R-23 or R-508B.
Today, manufacturers and users of ultra-low temperature refrigeration systems are forced to choose between acceptable cooling performance and the environmental impact of these systems. Existing non-flammable refrigerants R-23 and R-508B that are used in ultra-low temperature systems have GWP of 14,800 and 13,400 respectively. Klea 473A breaks this trade-off with energy efficiency comparable to R-23, capacity similar to R-508B, and a GWP of 1,830, which is a +85% reduction.
Optimum charge sizes per system are typically slightly reduced compared to R-23, giving a further potential reduction in GWP inventory per system. Customer trials are showing that existing system designs can easily adapt to this new refrigerant with little to no modification. New systems are also being actively designed to take advantage of the refrigerant’s unique properties.
Although Klea R-473A is not the only non-flammable alternative refrigerant proposed for use in very low temperature cascade systems, it has a significantly lower temperature glide, higher vapor pressure, and higher latent heat than other R-23 alternatives, making the adaptation of existing system designs more straightforward. Extensive trialling has also shown that it’s possible to operate climate chamber systems where the delivered chamber temperature is as low as -75C.
“We are delighted that Klea 473A was named Refrigeration Innovation of the Year at the 2022 Cooling Industry Awards. This award is fantastic recognition of our ongoing research and development program, and the hard work of all our teams. Koura is committed to innovation, providing customers across a variety of industries worldwide with new solutions and low GWP refrigerants to transform into a cleaner future.
This product will offer an easy adaptation option for system designers working in the very low temperature application areas who wish to significantly reduce their usage of ultra-high GWP refrigerants and who are contemplating larger system designs where non-flammability is an essential requirement of the refrigerant.”Gregg Smith, President of Orbia Fluorinated Solutions, said:
Koura is a global leader in the development, manufacture and supply of fluoroproducts that play a fundamental role in enhancing everyday lives.
