Thermo Clean®
Domestic water heating system for hospitals, sports centers, hotels as well as dwelling-houses
Application
ThermoClean® is a compact and ef­fective system solution for legionella free domestic water heating. Thermo­Clean® is suitable for hospitals, sports centers, hotels and dwelling houses, where effectively prevent the devel­opment and growth of legionella is needed. The system is available in two different types with separate reaction (-DL) or combination (-Combi) stor­age tank which contains the charging and recooling unit. These units are equipped with brazed (-DL/-Combi) plate heat exchangers.
Domestic hot water (DHW)
The ThermoClean® system uses the thermal disinfection method, where­by the reaction temperature inside the installation is kept at a constant tem­perature of 70 °C. It 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. The system is equipped with electronic controls for controlling of the charging temperature and the temperature in buffer storage tank.
Do mestic hot water circulation
The ThermoClean® system is supplied with connection for DHW circulation including balancing valve and a non­return valve as a standard as well as circulation pump as an option.
Options
The ThermoClean®-DL systems can be combined with additional buffer storage tanks to provide the required capacity for peak consumption. The system can be also equipped with the over-tapping protection to pre­vent system cool-down during over tapping.
Construction
The combination and reaction stor­age tank, plate heat exchangers and piping are made of stainless steel. All pipe connections are made by weld­ing. The charging and re-cooling unit is mounted on a separated common frame construction. After setup the unit should be connected with reac­tion (combination) storage tank.
