SAF-Holland and Carrier share sustainable project: the recuperation axle increases the Vector eCool range

SAF-Holland and Carrier Transicold are working together on an interesting project regarding sustainability and energy recuperation. In fact, SAF-Holland‘s SAF TRAKr e-axle for trailers – which is about to enter series production by the end of this year – will be used to increase the autonomy of the Vector eCool while driving.

SAF-Holland and Carrier acting as development partners

The partners SAF-HOLLAND and Carrier Transicold share the goal to provide their customers operating with heavy duty-trailers with a complete, 100% electric system with a plug & play solution in the long term. “We believe connecting the SAF TRAKr recuperation system to our Vector eCool will strengthen our position as pioneer in ultra-low-emission trailer refrigeration, with a solution that offers autonomous power, no direct emissions, and quiet operations,” said Victor Calvo, CARRIER TRANSICOLD International Truck & Trailer. “This partnership between two leading companies in the industry results in a high-performance and reliable solution that will offer a wider choice for our customers”.

The supply agreement follows a project in which Carrier Transicold engineers worked closely with the Volta Trucks development team to integrate engineless ‘Iceland’ all-electric refrigeration systems and PowerBox technology into the new Volta Zero.

“We have a very close and dynamic partnership and look with pride at the results of our cooperation so far: the SAF TRAKr has achieved very good results during the multi-year test phase and is now ready for series production,” says Christoph Günter, President Europe, Middle East and Africa as well as Chief Technology Officer at SAF-Holland.

This is how the system works

CARRIER TRANSICOLD supplies the recovery system for the SAF-HOLLAND’s e-axle, i.e. battery pack, control system and cooling unit. Energy recovery is used to generate electricity for the trailer refrigeration unit while driving. For this purpose, the centrally located high-voltage generator unit converts the kinetic energy generated by the trailer axle and brakes into electricity. This is temporarily stored in a lithium-ion battery pack or used to supply auxiliary consumers in the trailer with electricity while driving.
