Hultsteins, the Swedish and UK refrigeration systems manufacturer, will be showing its Ecogen Cost Saver fitted to a Buffaload Volvo LNG gas tractor unit at this year’s Road Transport Expo 2023.

Ecogen is an electric-hydraulic drive system that transforms diesel fridge units into electric operation when coupled to the tractor. 

It uses an engine PTO from the tractor engine to generate a constant 400V of electric to run the fridge on its built-in electric motor.

”The Ecogen Costsaver is a sustainable solution that is retrofittable,” said Graham Usher, Hulsteins MD, UK and Ireland. 

“It allows operators to run their fridge units on electric when coupled to a tractor; it  drives down carbon emissions by around 80%, slashing DPM by 98% and reduces NOx by 400% .

“It will also reduce R&M on the diesel engine of the fridge and cut fridge running costs”

The Road Transport Expo takes place from 28-30 June at NAEC Stoneleigh and is completely free to attend for show visitors; simply book an online entry ticket.

Usher added: ”We look forward to welcoming a wide cross section of visitors from the temperature-controlled and retail sectors, who will have the opportunity to see a live demonstration of the Ecogen running on an LNG tractor unit - Cooling on Gas!

“The tractor will be coupled to a G&A double deck trailer.”
