Electric Multi-Temperature Deliveries Are Here, Sunswap Sets a New Benchmark
Sunswap Sets a New Benchmark
At ZeroMission, we often talk about the inflection points that define the fleet transition to zero-emission operations. Sunswap’s latest breakthrough in electric transport refrigeration marks exactly that, a leap from “possible” to “proven” in one of the most complex areas of logistics: multi-temperature deliveries.
For years, the perception has been that electric refrigeration could handle straightforward, single-temperature operations, but would struggle with the nuanced demands of chilled, frozen, and ambient loads combined in one trailer. Sunswap has changed that narrative.
The Technology in Action
By integrating purpose-designed remote evaporators with their flagship Endurance unit, Sunswap has unlocked independent temperature control across multiple compartments. Operators can now configure trailers as lanes, bulkhead setups, or even double-decker arrangements, all powered without a drop of diesel.
Already on the road with Tesco, Cranswick, and Noble Foods, this capability is demonstrating in real-world conditions that electric TRUs are not just a replacement technology, they are an upgrade.
Remote evaporators are available in both 700mm narrow units and full-width compartment units, with either single or dual air flow.
Compact design means no loss of payload capacity, an essential factor for retailers and food producers moving high volumes daily.
Each compartment runs independently at its own temperature setpoint, whether chilled, frozen, or ambient.
Why It Matters
For logistics providers, multi-temperature capability is mission-critical. It means fewer vehicles on the road, consolidated deliveries, and optimised load factors. For sustainability managers, it eliminates the diesel refrigeration unit, a hidden but significant source of CO₂, NOx, and particulate emissions.
Michael Lowe, CEO of Sunswap, called it “a significant step forward in zero-emission multi-temperature operations,” and we couldn’t agree more. Fleet operators can now deliver frozen and chilled products in one zero-emission journey, no compromise on performance, no sacrifice on sustainability.
The Bigger Picture
ZeroMission sees Sunswap’s advancement as a blueprint for the future of food logistics:
Efficiency gains: Fewer trips, optimised trailers, and lower fuel/maintenance costs.
Sustainability impact: A clear reduction in both fleet emissions and urban air pollution.
Scalability: From retail giants like Tesco to specialist food producers, the model works across different fleet sizes and sectors.
With growing deployments across Tesco, Ocado, and Birds Eye, Sunswap is setting the bar for what’s possible in electric transport refrigeration. The shift isn’t just technological, it’s cultural. Fleets no longer have to ask “if” electric TRUs can handle the job, but rather “how quickly can we scale this?”
ZeroMission View:
Sunswap’s multi-temperature solution is more than an engineering feat, it’s a turning point for sustainable logistics. By addressing one of the toughest operational challenges in food distribution, it shows the industry that zero-emission fleets are ready for the mainstream.
At ZeroMission, we’re excited to help fleets plan, operate, and optimise these kinds of solutions as part of their wider FleetOps360° strategy, ensuring electrification delivers not only on carbon targets but also on cost, efficiency, and reliability.
