V450MB-E and V650MB-E support DC400–560V, -18°C to +25°C operation, with cooling capacity up to 6.51 kW and vehicle box volumes of approximately 12–35 m³.
The Corunclima e-PTO Electric Truck Refrigeration Unit is an electric refrigeration solution developed for EV trucks and refrigerated transport vehicles. Powered by the vehicle's high-voltage electric system, it uses a DC electric compressor to provide reliable cooling without relying on an engine-driven refrigeration system.
The V450MB-E and V650MB-E models cover different vehicle and cargo-volume requirements, with cooling capacity up to 6.51 kW and low-temperature operation down to -20°C. The system is suitable for various cold-chain applications while offering low-noise operation, efficient electric drive, and reduced dependence on engine idling, making it well suited to modern electric logistics fleets.
Electric-Powered – Designed for EV trucks and powered by the vehicle’s high-voltage electric system.
Engine-Independent Cooling – No engine-driven compressor required, supporting efficient refrigerated transport.
Wide Temperature Range – Supports operating temperatures from -18°C to +25°C.
Strong Cooling Capacity – Cooling capacity reaches up to 6.51 kW.
Multiple Applications – Suitable for food, fresh produce, frozen goods, pharmaceuticals, and other temperature-sensitive cargo.
Low-Noise Operation – Electric compressor technology helps reduce operating noise, especially suitable for urban and night-time delivery.
Two Model Options – V450MB-E and V650MB-E cover refrigerated box volumes of approximately 12–35 m³.
