Supermarket chain Waitrose & Partners is conducting a low emissions trial of a Carrier Transicold engineless Syberia TWINCOOL multi-temperature refrigeration unit specified on a natural gas-powered truck.
Funded through Innovate UK, part of UK Research and Innovation, Waitrose is working alongside researchers from the Centre for Sustainable Road Freight at the University of Cambridge as part of a year-long low emissions freight and logistics initiative aimed at showcasing how such a combination could dramatically cut fleet emissions.
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 is said to provide a continual, 100% refrigeration capacity even at the truck’s standard idle speed.
