Drive technology for electric pumping systems

To operate an electric transfer system that is not only intended or feasible for grid operation, a generator system is required in the towing vehicle. This allows the transfer process using an electric transfer system even when a customer power outlet with sufficient capacity is not available.

For this purpose, our EPT4 (Electric Power Train 4) drive system is designed. This unit is optimized for the maximum power of the electric motors used and is built for long-lasting performance.
