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.
