ThermoDual® Domestic hot water charging system

Description / Application ThermoDual® is the compact and eective

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 ecient 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 ows. This translates into greater operational eciency and predestines this system for utilization in district heating networks and in combination with condensing boilers. The optimum adaptation to the applicable specic needs in terms of storage capacity and output ensures a maximum of eciency, comfort and hygiene.

ThermoDual® – DHW charging system

Main components

Main components in standard system:

- DHW-approved charging pumps,

- Storage tank,

- Heat exchanger,

- Shut-o valve,

- Balancing valve,

- Safety valve,

- Thermometer.

Accessories The ThermoDual® system can be combined

with a second multiple DHW storage tanks for optimum tailoring to on-site conditions:

- Stainless steel domestic hot water storage tank, series SE, capacity 200 … 8000 liters (assembling / pipes by customer)

To connect circulation, system can be combined with pre-mounted circulation groups:

200 ... 1000 l high eciency pump (EEL <= 0,23)

100 l - without

≥ 200 l - 2 thermometers, 2 valves

For controlling DHW temperature self acting or electronical controllers can be used:

- self acting controllers VG/AVT/(STM)

- electronical controller ECL 110/210/310 (assembling by customer)

- other accessories see local pricelist
