July 2026 – The engineering team from Sunswap, a UK leader in zero-emission transport refrigeration technology, visited Shenzhen Yuzhan Electronics Co., Ltd. in Shenzhen. The two sides held in-depth discussions on the customized development and production supply of core wiring harness systems for new-energy transport refrigeration equipment. The Sunswap team also conducted an on‑site inspection of Yuzhan Electronics’ Shenzhen factory.

Founded in 2020 and headquartered in Leatherhead, Surrey, UK, Sunswap is a clean‑technology engineering company focused on the research, development and manufacturing of zero‑emission transport refrigeration equipment. The company was co‑founded by Michael Lowe, Nikolai Tauber and Andrew Sucis, with the mission of driving the global cold chain logistics industry to completely eliminate its reliance on diesel.

Sunswap’s core product, the “Endurance”, is the world’s first fully electric transport refrigeration unit designed specifically for battery and solar power. The unit completely eliminates diesel and achieves zero CO₂, zero NOx and zero particulate matter emissions during operation. Endurance combines modular battery technology with solar panels mounted on trailer roofs, delivering over 24 hours of continuous operation for frozen cargo on a single charge, and up to 2 months for chilled cargo. In actual operations, solar energy can supply up to 85% of the annual energy required, and operating costs are reduced by up to 81% compared with traditional diesel refrigeration units.
Backed by its leading technological capabilities, Sunswap has secured investment from top‑tier institutions including BGF, Shell Ventures and Barclays Bank, with cumulative funding of approximately $27.5 million. Its products are now available in six major markets: the UK, Belgium, the Netherlands, France, Chile and Australia. Clients include globally renowned companies such as Tesco, DFDS, Birds Eye and TIP Group. Sunswap is also a certified member of “Made in Britain” and has received the “Innovation of the Year” award at the 2024 Made in Britain Impact Awards, as well as the “Transport Refrigeration Manufacturer of the Year” award at the TCS&D Awards.

Founded in 2007, Shenzhen Yuzhan Electronics Co., Ltd. is a professional enterprise specialising in the R&D design, production and sales of terminal connection wiring harnesses and cable assembly, as well as providing complete connection solutions.
The company is located in Bao’an District, Shenzhen, and is equipped with 10 production lines, over 80 sets of processing equipment and more than 20 sets of testing equipment.
Yuzhan Electronics has obtained UL product certification and IATF16949‑2016 quality management system certification. Its products comply with RoHS environmental requirements and meet international quality standards such as IPC‑A‑620 and Q/T29106‑2014.

Yuzhan Electronics’ product lines cover new‑energy equipment wiring harnesses, automotive wiring harnesses, robotics equipment wiring harnesses, medical equipment wiring harnesses and other fields. Over the past decade, leveraging its strong technical capabilities and product quality, Yuzhan Electronics has successively become a core wiring harness supplier for leading domestic robotics companies such as Pudu, Keenon, Zerith and Youibot. In the new‑energy sector, Yuzhan Electronics has deep expertise in BMS wiring harnesses, charging pile/charging gun wiring harnesses, new‑energy vehicle wiring harnesses and renewable energy wiring harnesses, accumulating solid and extensive technical experience.
During this visit, the Sunswap engineering team focused on technical exchanges regarding the customisation of the core wiring harness system for the Endurance refrigeration unit. As the “neural network” of the refrigeration equipment, the wiring harness system is responsible for critical functions such as power transmission, signal control and data acquisition. Its reliability directly affects the stable operation of the equipment in extreme transport environments.

The Sunswap team toured Yuzhan Electronics’ production workshop in depth, gaining detailed insights into the company’s manufacturing processes, quality control systems and R&D capabilities. Yuzhan Electronics’ advanced fully automatic production equipment, rigorous and standardised quality control processes, and 20 years of accumulated engineering technology and refined production management experience left a profound impression on the Sunswap engineering team. The two sides held in‑depth discussions on core issues such as technical standards, reliability requirements and customised solutions for wiring harness products, and reached broad consensus on future cooperation in the supply of wiring harnesses for new‑energy transport refrigeration equipment.
This discussion is not only a business exchange between the two companies, but also marks a deep collaboration between globally leading clean‑technology enterprises—such as Swiss clean‑tech company Freesuns and Dutch clean‑tech service provider Sympower—and Shenzhen‑based companies.

Against the backdrop of continued growth in the global cold chain logistics market, the global cold chain logistics industry market size reached approximately $310 billion in 2024. In 2023, China’s cold chain market accounted for about 25% of the global total, with total cold chain logistics demand reaching approximately 350 million tonnes, a year‑on‑year increase of 6.1%. Sunswap’s zero‑emission refrigeration technology is redefining global cold chain logistics, while Yuzhan Electronics’ professional capabilities in high‑end wiring harness customisation will provide a solid supply chain guarantee for the mass production and global delivery of Endurance units.
Looking ahead, the two parties will fully leverage their respective core strengths in technological innovation and precision manufacturing to jointly promote the localisation of core components for new‑energy transport refrigeration equipment, contributing the wisdom and strength of “Made in China” to the green transformation of the global cold chain logistics industry.
