Koura, a global leader in the development, manufacture, and supply of 
fluoroproducts, has today launched the first of its next generation low GWP 
refrigerants, Klea(R) 473A, following proposed classification as an A1 
refrigerant by the ASHRAE SSPC34 committee.

Koura Klea(R) 473A is designed to achieve high performance with a significantly 
lower global warming potential (GWP) than existing refrigerants in ultra-low 
temperature cooling applications such as high value cold chains, vaccine 
storage, climate test chambers, transportation and other medical uses.

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 
used in ultra-low temperature systems typically have a high Global Warming 
Potential (GWP). Koura KLEA(R) 473A breaks this trade off with capacity and 
energy efficiency better than R23 and a GWP of 1,830, which is an 85% reduction 
compared to either R23 (GWP 14,800) or R-508 (13,396 GWP)

Klea(R) 473A is a game changing solution to the ever- increasing demand for 
ultra-low temperature refrigerants across various industries. Koura is 
currently in discussions with relevant stakeholders in a range of applications 
including deep sea shipping and bio-medical storage. This includes potential 
application in vaccine storage to support the fight against Covid-19. 

Koura is investing in significant innovations in its Koura Klea(R) range of 
refrigerant products and the launch of Klea(R) 473A is the start of the 
commercialisation of sustainable, energy efficient and low GWP refrigerant 
solutions with more products to come.

Dave Smith, Downstream Business Director at Koura said, "The launch of Klea(R) 
473A is an exciting milestone in our next generation refrigerant programme 
which aims to develop a new portfolio of sustainable, energy efficient, low GWP 
refrigerant solutions for a variety of heating, cooling and refrigeration 
applications."

Part of the Orbia community of companies, working together to tackle some of 
the world's most complex challenges, Koura is a leading provider of products 
and solutions across multiple industries including petrochemical, construction, 
automotive and pharmaceutical. Koura's Klea(R) refrigerant gases are trusted by 
the world's biggest organisations across commercial refrigeration, automotive 
and stationary air conditioning applications.
