Engine­less fridge units on trial

New Zealand LCV - - NEWS | ROUND-UP -

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.
