We have worked over a year now to develop a new power system for DEEP FREEZE vehicles. We have fitted two vehicles now with the first models of our new Alternator/ Inverter systems, followed by 8 more later this year.
When the final tests have been done, the complete fleet of 5500 vehicles will be fitted with the new system over the next 5-7 years. The system comprises: 1 x smart PM alternator plus mounting system to the engine of the Sprinter, 1 x 3.7 kW inverter, connected to the alternator. No battery in the system needed, the compressors are powered during driving. Even at 800 rpm the system is delivering 3 kW. Now the BOFORST vehicles keep their ‘morning’ temperature and are independent of the grid.
