The diesel generator Hahn & Sohn HDE20SS3-DW (Stage 2) is a compact and efficient three-phase power source designed for industrial and commercial applications. It is equipped with a reliable WEICHAI WP2.3D25E200 engine – a four-cylinder, water-cooled unit with direct fuel injection.
- The generator delivers a rated power output of 18 kW (22.5 kVA) and a maximum power of 20 kW (25 kVA). Thanks to the automatic voltage regulator (AVR), it ensures a stable electrical output suitable even for powering sensitive devices.
- The Ultra Silent design reduces noise to just 51 dB(A) at 7 m, allowing its use in environments with strict noise requirements. Control and monitoring are provided by the ComAp HGM4010N unit.
- This model is ideal as a backup power source for small industrial facilities, agricultural operations, or commercial buildings, as well as a primary power source in locations without access to the electrical grid.
