The trial will document how much Carrier Transicold’s Syberia refrigeration unit, combined with a Scania P280 rigid truck using a natural gas truck engine, can lower CO2 emissions and further improve fleet efficiency.
“We have specified Carrier Transicold units for many years and they continually impress us with their performance,” said Simon Gray, vehicle fleet engineering manager, Waitrose & Partners. “We wanted to put the engineless solution to the test and monitor performance across a full 12-month period. The results of the trial will likely guide our future fleet specification – hopefully allowing us to focus on continuing to improve the sustainability of our transport operations.
The Syberia TWINCOOL runs entirely on hydro-electric power generated by the truck’s ultra-clean Euro 6 engine, cutting emissions by removing the diesel engine inside the refrigeration unit. The refrigeration unit is powered by Carrier Transicold’s ECO-DRIVE GenSet, driven by a hydro pump connected to the truck’s power take-off motor. The hydraulic system drives a generator that delivers electrical power to the host unit and provides a continual, 100 per cent refrigeration capacity even at the truck’s standard idle speed.
Industry testing has shown natural gas vehicles to benefit from lower exhaust and noise emissions compared with diesel engines. The Syberia unit contributes to this quiet operation with a PIEK-compliant noise level of 60 dB(A) at 100 per cent capacity.
The Waitrose & Partners commercial vehicle fleet currently includes more than 400 Carrier Transicold units, which have been specified over the past eight years.
