Full electric refrigeration units for medium size vans and trucks using non-flammable HFC-134a or the HFC/HFO refrigerant R-452A received the European Transport Award for Sustainability 2020. When used with electric vehicles it offers zero-emission refrigerated transport for food deliveries for urban populations, creates refrigerated transportation that delivers food and perishable items safely with zero-emission, low noise and maximum convenience for urban populations.
Depending on cooling capacity and temperature requirements the units are available with non-flammable R-134a (0°C evaporator) or HFC/HFO blend R-452A (0°C or -20°C evaporator). The electric units use customized components, including a variable speed compressor and patented power management, for lower energy consumption, higher efficiency and reliability. Designed for both electric and engine-powered vehicles, the unit can be supplied with optional battery pack or use the vehicle’s secondary battery for hold over capacity during stops for deliveries or breaks. This feature also increases the sustainability of delivery operations as the driver can turn the engine off during stops to reduce fuel consumption and emissions. The unit is also compatible with vehicle’s start-stop features contributing to additional fuel savings.
