About Vector E-Cool

The UK’s first Vector eCool – the industry’s only fully autonomous, all-electric refrigerated trailer system – has been fitted to a new Gray & Adams 13.6-metre demonstrator trailer  that is now on the road and showcasing the cutting-edge technology to our customers. Built into a twin member trailer, the Vector eCool utilises a new energy recovery and storage system which converts kinetic energy generated by the trailer axle and brakes into electricity, which is then stored in a battery pack that powers the refrigeration unit. This loop creates a fully autonomous system that produces no direct carbon dioxide and doesn’t require any modification to the tractor unit or the fitting of expensive eco drives and PTO’s.
