Greggs has taken delivery of three new hybrid refrigeration units designed to help lower its environmental impact of its logistics in central London.The new T- and UT-Series Hybrid refrigeration systems from Thermo King, a Trane Technologies brand, can switch between diesel and electric mode, allowing transporters to operate in inner cities, residential areas and low-emission zones with the unit’s diesel engine turned off.Greggs is one of the first customers in Europe to take delivery of the system.“We’re very conscious about the sustainability of our transport operations. It is paramount for us to operate in inner cities with as little noise and emissions as possible,” said Richard Penna, group logistics manager at Greggs.“It was a natural choice to work with Thermo King and equip our trucks with these new units that can easily switch from diesel operation to electric, reduce the sound level and eliminate emissions. On top of that we expect to benefit from the lower daily fuel consumption.”The new hybrid single- and multi-temperature solution for trucks feature Frigoblock alternator and inverter-drive technology. The nose-mount T-Series Hybrid and under-mount UT-Series Hybrid refrigeration automatically switches between electric and diesel operation as required or necessary.It added that the driver only needs to set the vehicle when leaving the depot and the system will switch electric and diesel modes during the working day depending on the unit’s requirements.The food-to-go and bakery specialist has used Thermo King units for several years, Penna added.“Thermo King Hybrid technology was designed to help transport and delivery companies’ future-proof their refrigerated operations and investments. With this solution they can stay ahead of regulations, control their total cost of ownership and achieve important sustainability goals,” added Colm O’Grady, product manager at Thermo King.
