Sunswap’s zero-emission solar-powered transport refrigeration unit (TRU) delivers the same level of performance as a traditional diesel powered unit, according to data from a recent trial.

The findings come from a trial of the Sunswap Endurance TRU, conducted by Moores Refrigeration Controlled Transport (MRCT), which specialises in chilled and frozen food distribution.

Sunswap Endurance uses battery technology and on-board solar power generation to provide zero direct emission refrigeration. During the trial, 73% of the energy used by the Sunswap Endurance unit came from on-board solar generation.

The trial also demonstrated that the performance of Sunswap Endurance in temperature-controlled transportation matched that of traditional diesel-powered units, maintaining optimal performance while significantly reducing environmental impact.

MRCT said integrating just one Sunswap unit into MRCT’s fleet would deliver projected annual savings of 113 tonnes of Scope 1 CO2 emissions, 1.1 tonnes of NOx, and 34kg of particulate matter.

David Brown, MRCT MD, said, “We were impressed by the performance of Sunswap’s Endurance unit during our trial.



”Not only did it maintain optimal temperatures throughout our chilled delivery routes, but it also significantly reduced our environmental impact.

”Our drivers and traffic teams also found the system user-friendly and easy to use.

”The Sunswap Endurance system fits seamlessly into our fleet, proving that transitioning to sustainable solutions doesn’t have to come at the cost of performance or user acceptability.”

Alastair Gough, Sunswap head of business development, commented, “We are thrilled to see our zero-emission transport refrigeration unit performing seamlessly in real-world conditions with MRCT.

”The positive feedback from their team shows how again-and-again Endurance is a viable zero-emission solution that is not only better for the environment but also easily integrated into existing fleet operations.”
