ThermoClean®
Domestic water heating system with legionella growth prevention through thermal disinfection
Description / Application |
|
|
The ThermoClean® system is compact and |
||
|
|
||||
|
|
|
effective solution for legionella-free domestic |
||
|
|
|
water heating. The system uses the thermal |
||
|
|
|
disinfection methods, whereby the reaction |
||
|
|
|
temperature inside the installation is kept at |
||
|
|
|
a constant temperature of 70 °C. |
||
|
|
|
The ThermoClean® system is dimensioned |
||
|
|
|
in such a way that the water is warranted to |
||
|
|
|
remain in the reaction area of the device for |
||
|
|
|
at least 5 minutes. During tap operation, the |
||
|
|
|
reaction temperature of 70 °C is cooled down to |
||
|
|
|
the required hot water temperature within the |
||
|
|
|
system. This is not achieved by the addition of |
||
|
|
|
cold water, but through an additional re-cooling |
||
|
|
|
heat exchanger which cools the disinfected |
||
|
|
|
water, while preheating cold water, that |
||
|
|
|
simultaneous preheat the cold water. |
||
|
|
|
The hot water temperature can be set at |
||
|
|
|
any temperature between 50 °C and 60 °C.1 |
||
|
|
|
It means that the installation of a scaling |
||
|
|
|
protection device on the taps is redundant if the |
||
|
|
|
temperature is adjusted accordingly. |
||
|
|
|
Due to the connection of the circulation into the |
||
|
|
|
system a continual thermal disinfection of the |
||
|
|
|
hot water is ensured. |
|
|
|
|
|
The high quality stainless steel design of reaction |
||
|
|
|
and buffer storage tank, heat exchanger and |
||
|
|
|
piping is hygienically perfect, offers a maximum |
||
|
|
|
in operational safety and can be universally used |
||
|
|
|
in combination with the wide range of materials |
||
|
|
|
used in the connected domestic water supply |
||
|
|
|
network. |
|
|
|
|
|
1 The recommended temperature is 60 °C. |
