A 10kVA Diesel Generator Built to Run Cool Under Real Load: The Hyundai DHY12000XSEM-RS
Water cooling changes what a diesel generator can handle. The Hyundai DHY12000XSEM-RS is a genuine 10kVA unit built around a water-cooled Hyundai EV80 diesel engine, giving it the thermal headroom for sustained, demanding standby duty that an air-cooled unit would struggle with over long runs. A 30 litre tank and key or remote start (with ATS compatibility) round it out as a serious standby option for properties and businesses that need power they can rely on for the long haul.

Why Water Cooling Matters Here
- Built to sustain load: water cooling gives the engine more thermal headroom than air-cooled equivalents, better suited to long duty cycles.
- Genuine capacity: 10kVA / 8kW maximum output from the Hyundai EV80 diesel engine.
- Large tank: 30 litres to reduce refuelling stops during extended runs.
- Flexible starting: manual key start or remote start/stop, with ATS compatibility for automatic operation.
- AVR alternator: clean, stable power output for sensitive equipment as well as heavy loads.
- Two outlet types: 1 x 32A and 1 x 15A 240V RCD-protected outlet.
- Backed by Hyundai: 1 year or 500 hours warranty, whichever comes first.
