CARRIER HITS -40°C WITH R744

TRANSPORT refrigeration specialist Carrier Transicold has upgraded its Naturaline refrigeration units to deliver a sustainable -40°C climate using R744 (CO2) refrigerant.

Jim Taeckens, senior product manager of Carrier Transicold’s global container refrigeration division, said: “The -40°C capability can help shipping lines – especially those seeking environmentally responsible solutions – to provide enhanced offerings for customers who prefer colder frozen temperatures for maintaining quality attributes of some premium cargos, like ice cream, shrimp, sushi and other seafood over lengthy voyages.”

This improved performance of the Naturaline container refrigeration units has been achieved with a series of software revisions. These changes better exploit the performance of the environmentally friendly R744 used, improving significantly on the stated -29°C previously achieved by the Naturaline. 

The Naturaline unit’s new ‘deep-frozen capability’ is now standard in all newly purchased units, while existing setups can be upgraded with a software update.

Standard features otherwise remain unchanged and include a variable speed two-stage compressor and two-speed cooling fans – which help cut power consumption and deliver optimum performance.
