Hultsteins, the Swedish truckrefrigeration manufacturer, recently showed a range of environmentally sustainable diesel-free systems at this year’s CV Show which, say the company, set a new standard in lowcost, high-performance transport refrigeration.

Embracing hydraulic technology which draws energy from the truck engine and converts it into power to drive the refrigeration unit, Hultsteins has incorporated its long-term UK manufacturing partner Cold Connect to produce a unique range of on-board powergenerating units for single and multi-temperature goods transport. Reducing fuel costs by up to 60% the Hultsteins/Cold Connect systems work with rigid truck and tractor engines to cut Co2, Nox and particulate emissions, while significantly reducing maintenance and complying with urban emissions regulations – unlike conventional diesel-driven refrigeration units.

Four systems were on display, two from Hultsteins, produced in Sweden and two from Cold Connect, manufactured in the UK.

Cold Connect Ecogen EG25 and SG25

Developed by Cold Connect for truck or tractor units, Ecogen is a slim-fit hydraulic drive generator which connects to the engine’s PTO and simply plugs in to any refrigeration unit with mains electric operation. Fuel consumption and emissions are reduced while generating a constant 400-volt, 3-phase electrical power to the same standard as the mains supply.

Hultsteins HS215 and HU13

Produced in Sweden by Hultsteins, using hydraulic technology perfected since 1962, these units are front and undermounted respectively and designed for single and multitemperature applications. Again, connected directly to the truck PTO, the HS215 and HU13 deliver constant full-power regardless of the engine speed. Both systems significantly reduce fuel and maintenance costs while cutting CO2, Nox and PM emissions.
