Hahn & Sohn Diesel Generator HDE20SS3-DR (Stage V) Euro 5

The diesel generator Hahn & Sohn HDE20SS3-DR (Stage 5) is a next-generation three-phase power source designed in compliance with the strict EU Stage V emission standard. Equipped with a RAYWIN 4F24TIG11 engine — a four-cylinder, water-cooled, direct-injection diesel — it delivers high efficiency, reliability, and environmentally friendly operation.

• The generator provides a rated power output of 20 kW (25 kVA) and a maximum output of 22 kW (28 kVA). A built-in automatic voltage regulator (AVR) ensures stable electrical output, protecting even sensitive devices from voltage fluctuations.
• The Ultra Silent soundproof enclosure keeps the noise level as low as 51 dB(A) at a distance of 7 m, which is outstanding in this power category. Control and monitoring are handled by the modern ComAp InteliLite 4 AMF25 control panel, providing clear and reliable supervision of all operating parameters.
• This model is suitable for industrial facilities, commercial buildings, telecommunication bases, and agricultural operations, as well as a backup power source in case of grid failure.
