Founded in 2020, Sunswap is a sustainable transport refrigeration system usable, for instance, in supermarket distribution warehouses and delivery lorries, which, through its Endurance product, has developed a battery and solar-powered transport refrigeration unit. 

Sunswap believes that by designing, developing and manufacturing a refrigeration system that breaks free from legacy technology, they are spearheading transition towards zero tailpipe emission, without compromising performance.

At the UK’s top net-zero conference, Innovation Zero, held on the 30th April and 1st May in London’s Olympia, Sunswap Endurance was recognised, picking up an award in the Transport category for Mature Solutions.

The product

Sunswap say that Endurance has been designed to minimise energy consumption, without compromising on cooling power or durability. The size of the battery will be tailored to the delivery cycle and mode, providing the right amount of power without excess weight.  Its battery pack weighs 10-20 % less than diesel equivalents.

Using the latest technology available, its cloud prognostics continuously monitor performance and system conditions before difficulties appear. It can be operated remotely, and it is equipped with versatile temperature control which can be tailored to anything between -25℃ to +25℃.

The use of solar power contributes to the low running cost of the product, providing around 86% of the electricity needs.

Several big companies are currently trialling the products, the most recent company being the supermarket giant, Tesco.

Innovation Zero was launched in 2023 by CleanTech Events. The company is chaired by the Conservative MP and former minister Liam Fox, and is a UK government partner.
