Sunswap Endurance Units a cool, clean energy change for transport refrigeration
Solar-assisted electric transport refrigeration units replace diesel for lower emissions outcomes
A $10 million CEFC investment commitment is backing the deployment of more than 100 solar-assisted Sunswap Endurance Transport Refrigeration Units (TRUs) to reduce emissions across Australian refrigeration retail and logistics fleets.

Australian refrigerated transport has put up with diesel’s costs and limitations for too long, not because operators wanted to, but because there simply wasn’t a credible alternative. Sunswap changes that.Grant TurnerGeneral Manager, Protran Solutions
Our investment
The CEFC has committed up to $10 million to support the deployment of more than 100 Sunswap Endurance TRUs across the Australian refrigerated retail and logistics fleets.
Refrigeration is a critical component of Australia’s food and pharmaceutical supply chains.
The Endurance refrigeration units, distributed in Australia by Protran Solutions, are fully electric and solar-assisted. The units are designed to replace diesel-powered units commonly fitted to refrigerated trailers.
The CEFC investment, through the Powering Australia Technology Fund, is aimed at accelerating the availability of the technology in Australia by addressing a key barrier to adoption - the upfront costs of manufacturing and importing advanced refrigeration units.
OUR IMPACT
A lower emissions logistics alternative
Australia represents a significant opportunity for electrifying transport refrigeration, with cold chain logistics estimated at up to US$5 billion.1
Between 70 and 90 million litres of diesel are used each year to fuel the refrigeration systems in Australian refrigerated transport, which accounts for nearly five per cent of total diesel consumption.2
Cold chain logistics has traditionally relied on diesel-powered refrigeration, with fuel costs and high maintenance accepted as the price of doing business.
Using proven electric alternatives enables emissions reduction, improves air quality and can lower operating costs for Australian businesses.
Sunswap’s Endurance performs in Australian conditions
Sunswap’s Endurance units are already in use across Europe and South America and the technology has demonstrated strong performance in Australian conditions.
A three-day trial of a 1,671km route between Sydney and Brisbane was completed without the need for en route charging. At the end of the trip, 62 per cent of battery charge remained.
High solar contribution, particularly given Australia’s climate, is expected to play a key role in reducing electricity demand and operating costs.
The CEFC investment puts more units on Australian roads, giving operators access to electric refrigeration that cuts operating costs, handles Australian distances, and comes with the service infrastructure to back it up.Michael LoweCEO and Co-founder, Sunswap
