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.
