Engineless fridge units on trial
BRITISH SUPERMARKET GIANT TESCO IS trialling two engineless refrigeration units which run entirely on the hydro-electric power generated by trucks’ powertrains.
The units, developed by Carrier Transicold, are mounted on Mercedes-benz trucks fitted with rigid box bodiess and will be in service for seven days a week.
They’ll transport chilled and ambient produce to urban Tesco Express and Tesco Metro stores across southwest England and southern Wales. Each vehicle will be kept in the fleet for eight years and is expected to cover 56,500 kilometres a year.
The systems remove the need for a separate diesel engine as they are driven by an Ecodrive Genset power unit, which is powered by a hydraulic pump connected to the truck’s engine power take-off.
The hydraulic pump drives a generator that delivers electrical power to the refrigeration unit and provides a continual, 100 percent refrigeration capacity even at the truck’s standard idle speed.
The low noise units are ideally suited to intensive urban delivery work. In addition, the slim-profile evaporator offers greater load space than a standard fridge unit.
The trial is part of the supermarket retailer’s efforts to reduce its impact on the environment.
