Sainsbury’s trials trailer with natural refrigerant

Sainsbury’s has become the first company in the world to take delivery of Carrier Transicold’s prototype natural refrigerant trailer unit.

The new generation of transport refrigeration system for trailers operate exclusively with carbon dioxide (CO2) refrigerant, which has a global warming potential (GWP) of just one making it the baseline against which all other refrigerants are measured. The GWP of CO2 is also lower than other natural refrigerants, such as propane and ammonia and it is non-ozone depleting.

The delivery marks the first of three units to join the Sainsbury’s fleet this year as part of a three-year technology field trial and builds on the success of a 2013 pilot, which saw the supermarket operate a modified refrigeration system for ocean containers – making it the first naturally refrigerated trailer operating anywhere in the world.

Gary King, operations support manager for Sainsbury’s commented, “The beauty of Carrier Transicold’s prototype trailer unit is it delivers a massive reduction in F-Gases by using natural refrigerant. This will directly help us achieve our ambitious environmental and sustainability goals, whilst delivering a seismic leap forward in terms of sustainability within the cold chain.”
