The new car-derived refrigerated vans, equipped with the all-electric refrigeration system using non-flammable HFC-134a, support plans to comply with the tightening emissions legislation. The all-electric refrigeration system was selected as the ideal choice to create a zero-emissions electric vehicle with enough range to carry out most urban delivery operations. The roof-mounted, 12-volt refrigeration unit has less than 1kg of HFC-134a. The hermetic refrigeration system is delivered pre-charged with refrigerant and pre-tested by the factory ensuring containment. The unit’s design also features an ultra-slim profile, helping to improve vehicle aerodynamics and the range of use.
The new electric vans do not use an alternator, which requires the refrigeration units to be powered by an autonomous lithium-ion power source. Using a standalone power source provides up to seven hours of cooling power, and allows a range of around 110 miles depending on the use and application of the vehicle. Relying on the vehicle batteries to drive both the van and refrigeration unit limits the range to 60 miles, which would not be sufficient for many applications. The refrigeration unit batteries are charged separately through their own charging point and are small, light and clean, meaning they can be incorporated within the vehicle with minimal impact.
