HWM 100 B

The HWM 100 B hot water module is an energy-efficient, diesel-operated instantaneous water heater with integrated buffer tank. It guarantees a constant supply of hot water even with incoming water of varying temperatures and greatly fluctuating usage quantities.

With a heating output of 105 kW and a boiler capacity of 125 litres, the HWM 100 B can heat water to a selectable temperature of 80 °C maximum. This unit was developed especially for conditions in which extremely varying quantities of hot water are consumed. Even with variable incoming water temperatures and greatly fluctuating consumption (from one washbasin to several showers), the insulated buffer tank makes sure the temperature remains constant. With a consumption of less than 10 l/h, the diesel burner is up to five times more efficient than heating the water with electricity, leading to considerably lower running costs. The HWM 100 B conforms to international drinking water standards and also enables complete, autonomous thermal disinfection of all integrated surfaces that come into contact with drinking water. This ensures perfect hygiene in the field without the need to transport special cleaning agents.
