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.
