Hultsteins Partners with Addvolt for Sustainable Refrigeration Solutions

Hultsteins, a producer of sustainable refrigeration and electric generator systems based in the UK and Sweden, has partnered with Addvolt, a leading vehicle battery pack manufacturer, to offer sales and support in the UK and Ireland. 

Addvolt, headquartered in Porto, Portugal, designs and manufactures a variety of Powerpacks and Power Units (ePTO), which provide refrigeration operators with clean energy by reducing diesel consumption, CO2 emissions, noise levels, and maintenance costs. The company has created the world’s first Plug-In Hybrid Powerpack for electrifying auxiliary systems on heavy-duty vehicles and supplies markets in 20 countries across three continents. Recently, Addvolt introduced the ePTO, capable of powering 400V AC fridge units from BEV traction batteries.

By integrating Addvolt’s powerpack with Hultsteins' onboard power generator, Ecogen2, cold chain transporters can achieve 100% electrically-powered refrigeration for both urban and long-distance deliveries. This combination eliminates fuel costs and pollution from diesel-powered refrigeration, while offering quiet, low-maintenance, and ULEZ-compliant solutions. Ecogen2, fitted to the power take-off (PTO) of the tractor unit, converts any diesel fridge to full-electric operation at a fraction of the replacement cost.

Hultsteins' sustainable systems are widely used across Europe and the UK. The partnership with Addvolt ensures a continuous electrical supply to refrigeration units, offering significant cost and carbon savings. Addvolt’s PIEK-compliant plug-in hybrid powerpack can be charged at any warehouse and, with an added generator, provides hybrid recharging while in motion, enhancing road efficiency and sustainability. The collaboration aims to transform diesel engines into electric fridges and provide a cleaner transportation solution.
