      This is part of a range of alternative technologies that can be used to power existing trailer systems, Dargan adds. “Carrier Transicold’s ECO-DRIVE modules, for example, allow operators to run multi-brand rigid and trailer fridges on electric power using the truck or tractor unit’s own motive power source, be that diesel, gas, electric or even hybrid.”
But Dargan points out that there
is no demise of diesel imminent, so
the company continues to develop
and improve its range of standard temperature-controlled units. “Every engine on a Carrier system in the EU being notably cleaner than the Stage V Non-Road Mobile Machinery standard,” he adds.
While the demise of diesel isn’t imminent, the tax relief on red diesel is, which temperature-controlled operators need to be aware of, according to Hultsteins, the British and Swedish hydraulic refrigeration and electric hybrid systems manufacturer.
The company warns that operators should prepare early for the impending withdrawal of the tax rebate on red diesel and refers to a HMRC paper that states all TRUs must be emptied of red diesel and re- fuelled with white from April 1, 2022.
Further, Hultsteins point to the detail regarding the replacement of white diesel by advising that while it is necessary to run down all the red diesel in each tank, it is not mandatory to first clean the system.
Hultsteins’ UK managing director, Graham Usher, explains: “Some operators may be of the belief that the existing red diesel in each tank can be used until empty from April 1 and thereafter that the tank should be cleaned. In fact, according to a white paper produced by HMRC - this is not so in both cases and continued use of red diesel from this date can attract a £250 fine for each unit, while the expense in terms of labour and downtime to flush out the system need not be incurred.”
HMRC advice states: “...the Government expects users of vehicles and machinery losing their red diesel entitlement to ensure that they do not purchase red diesel for use from 1 April 2022 and run down their existing stocks before that date.”
However, according to Hultsteins, while operators should make these preparations ahead of the price increase, they can avoid the significant cost burden by fitting an engine drive PTO, to power an on-board electrical generator which will drive their existing fridge. Hultsteins also has a hydraulic fridge system that can be fitted to any truck or drawbar system and stop using diesel altogether, which helps to reduce their environmental impact.
Alan Hunt, UK managing director
– sales and marketing at trailer manufacturer Schmitz Cargobull, agrees that registered fuel suppliers that switch a fuel tank from red to white diesel will need to flush out the tank and supply lines until no trace of marked rebated fuel remains. “This will help to ensure compliance and minimise the risk that white diesel that has had the full duty rate paid on it is contaminated with the red diesel marker,” he says. “This means the operator will have to resort to diesel fuel, which will be taxed at a higher rate and lead to higher costs.
