2 Diver Electric Hot Water Machine

Ordering Code: DHM-E02

The Synergy Bell Electric Water Heater is a compact, popular and ideal for diver heating applications.

The heater unit offers a high capacity heating solution in a robust stainless steel frame with a small footprint that makes effective use of available deck space. Five banks of individually switched heater elements heat the supply water up to 42°C (74°F) above the ambient or supply temperature and by selecting a suitable bank or combination of banks, basic water temperature control is achieved. The finer control of the output water temperature is accurately maintained to within ±1ºC of the required set point by an electronic controller actuated valve
