Sunswap launches Endurance in Spain to cut refrigeration costs and emissions
Key takeaways
- Sunswap enters Spain via SOR Iberica, signaling fast EU adoption of electric reefers driven by cost and emissions pressure.
- Endurance delivers up to 24 hours of frozen or up to two months of chilled operation, with up to 81% lower operating costs vs. diesel units.
- Live temp and performance data give fleets real-time cold chain visibility, reducing rejected loads and compliance risk.
Sunswap recently entered the Spanish market, expanding its electric refrigeration footprint across Europe and beyond. The company, which builds battery-powered transport refrigeration systems, is entering Spain through a partnership with SOR Iberica to provide operators with access to its Endurance unit.
The move follows Sunswap’s recent expansion into France, the Netherlands, Chile, and Australia since late 2025. The partnership gives Spanish operators a direct route to trial and purchase Endurance, a battery-powered refrigeration unit with trailer-top solar designed to extend range and reduce charging needs.
Carreras, a logistics operator running more than 1,000 vehicles across Spain and Portugal, will be among the first to deploy Endurance starting in May 2026. Additional trials with Spanish operators are already confirmed, with more details expected to be shared publicly.
Endurance delivers up to 24 hours of frozen operation and up to two months of chilled operation from a single charge. The system has achieved up to an 81% reduction in refrigeration operating costs compared to diesel across customers, including Tesco, DFDS, Ocado, and Birds Eye. The unit continuously generates performance and temperature data, giving operators real-time visibility into cold chain conditions rather than relying on post-delivery issue detection.
"The speed at which operators across different markets are moving on this tells you something,” Michael Lowe, CEO of Sunswap, stated. “France, Chile, Australia, and now Spain, all within months of each other. We are entering these markets based on demand for Sunswap and electric transport refrigeration. The interest we've seen in Spain before we've even formally launched here is a good indicator of where this market is heading."
