ThermoDual®

Domestic hot water charging system

Description / Application			ThermoDual® is the compact and effective
			domestic hot water (DHW) charging system.
			Due to the consistent use of carefully selected
			components and highest quality materials, the
			compact the ThermoDual® system meet all of
			the requirements for the prevention of legionella
			growth.
			The highly efficient heat transfer of the heat
			exchangers enable The ThermoDual® system to
			attain low heating water return temperatures
			across the entire cycle of a tank charge, thus
			reducing the required media flows. This
			translates into greater operational efficiency and
			predestines this system for utilization in district
			heating networks and in combination with
			condensing boilers. The optimum adaptation to
			the applicable specific needs in terms of storage
			capacity and output ensures a maximum of
			efficiency, comfort and hygiene.
