Temperature controlled logistics specialist Gist has commenced a trial of the UK’s first fully autonomous, all-electric engineless refrigerated trailer system, the Vector eCool, developed by Carrier Transicold and Gray and Adams.

The 13.6 metre electric trailer is being used for store deliveries of fresh and chilled foods to well-known UK supermarkets.

This new technology uses an under-mounted battery to power the fridge system and, when driving, converts kinetic energy generated by the trailers’ axle to replenish the battery pack and in turn power the refrigeration unit.

Unlike current refrigeration systems, this loop creates a fully autonomous system that produces no direct carbon dioxide or particulate emissions. The fridge is lighter than the standard fridge and associated red diesel fuel tank and very quiet making, it suitable for overnight urban deliveries.

Mick Pethard, Head of Engineering, Gist, said: “We are always keen to trial new technologies and this is an exciting new product for us to explore. We’ve partnered Carrier refrigeration for a number of years to help us on our journey to improve fuel efficiency and Gist’s sustainability.”
