Co-op completes trial of new Supra HE

Co-op has successfully completed the first UK trial of the new Carrier Transicold Supra High Efficiency (HE) 11 Multi-Temperature (MT) truck refrigeration unit. During  six months on the road, the new unit is said to have demonstrated how it can deliver significant fuel savings, reduce noise and lower operating costs compared to Carrier Transicold’s legacy Supra systems.

Mounted to a 26-tonne DAF CF rigid with a two-lane insulated body from Gray & Adams, the new Supra HE 11 MT underwent performance testing alongside one of Co-op’s existing Supra 1150 MT units across several key benchmarks. The Supra HE 11 MT reduced fuel consumption by 25% and used 10% less electricity while on standby. This combination could save nearly 2.5 tonnes of carbon dioxide (CO2) per unit annually. These results have led Co-op to invest in 86 Supra HE 11 MT systems, due for delivery in 2025.

“In the two decades we’ve worked with Carrier they have continually supported our commitment to embracing the latest technologies, and this trial represents the next step for the business as we strive toward our 2035 Net Zero ambitions,” said Nicholas Orwin, General Manager Fleet and Compliance, Co-op. “We’ve been hugely impressed by the results and moving forward the Supra HE will be the unit of choice for our rigid truck fleet, delivering huge sustainability benefits while also helping us provide the optimal work environment for our drivers.”

The Supra HE 11 MT combines mechanical and electrical subsystems into a quieter, lighter and more compact unit that delivers enhanced efficiency, performance and uptime. Additional sustainability benefits are achieved with a 30% reduction of brazed joints, helping to minimise potential refrigerant leakage. The trial unit demonstrated a 2dB(A) noise reduction compared to the Supra 1150 MT. This is a key factor for enhancing driver comfort and reducing the impact on residents during urban deliveries – both essential factors for Co-op.

In addition to the new Supra HE 11 MT units, Carrier Transicold will also provide an additional 106 temperature-controlled systems into Co-op’s fleet in 2025, including flagship Vector HE 19 and Vector HE 17 trailer units.
