With the delivery of 25 new trailers, each mounted with Carrier Transicold’s Vector® 1850 multi-temperature low-noise refrigeration systems, Waitrose has begun a major trial of Carrier’s innovative Vector technology within its 320-strong fleet of refrigerated trailers.

The specification of the Vector 1850 unit on each of the new 13.2 metre Gray & Adams trailers is the result of a decision by Waitrose Fleet Engineer Ray Collington to evaluate the front wall-mounted Carrier Transicold units in comparison with the undermount temperature controlled systems traditionally fitted across the fleet.

Commenting on the new trailers, Collington said: “We wanted to see how a regular front wall-mounted refrigeration unit would perform, so we worked closely with Carrier Transicold and Gray & Adams to design a trailer which would meet our bespoke requirements. Selecting the Vector 1850 system also allows us to put Carrier’s all-electric technology to the test for the first time.”

Carrier’s patented all-electric technology is designed to reduce the number of serviceable parts, such as belts, clutch and shaft seal, in every Vector 1850 refrigeration system to help lengthen the product life and enhance reliability. Furthermore, 94 per cent of the components used in a Vector 1850 unit can be recycled at the end of its operating life.

Each Vector 1850 offers unparalleled pull down and temperature control, with the unique ability to cool and heat at the same time. This enables Waitrose to accurately maintain different set points ranging from -30C to +32C in each of the trailer’s three compartments.

The temperature in the front compartment is regulated by the Vector 1850 host unit, with a powerful full-width dual-discharge evaporator, ensuring different set points are maintained in the centre and rear compartments.

The new trailers are operating from Waitrose’s regional distribution centre in Bracknell, Berkshire, making deliveries to Waitrose stores across southern England. These locations include both high street and suburban sites, with the Vector’s low noise kit ensuring sound emissions do not exceed 72 decibels.

Each trailer has been supplied with a 10-year Golden Cold® fixed cost repair and maintenance agreement. This includes all maintenance recommended by Carrier Transicold, carried out by manufacturer-trained technicians using genuine replacement parts, plus 24-hour breakdown assistance throughout the UK.
