DESCRIPTION
The air treatment unit essentially represents a thermal group that exchanges the combustion products of a
forced-air gas burner with an air flow generated by a group of highly efficient fans.
The air to be heated is sucked by the latter and when it touches the hot surfaces of the heat exchanger, the
air temperature rises; the air can be distributed both directly and through special ducts.
The characteristics of the centrifugal fan make the equipment suitable to be installed on plants needing the
distribution of hot air through ducts or, in general, when it is necessary to have static pressure.
This heating system makes it possible to remarkably reduce the plant costs and ensure savings in operating,
being particularly suitable for discontinuous and occasional use.
The special configuration of the counter-current flow heat exchanger optimises the heat exchange and
makes the equipment to work
with condensate
.
Besides, the equipment is realised in a way that it can operate with variable heating power and air flow, in
order to adapt to the real heating requirements of the environment.
In summer it is possible to operate the ventilating unit only.
GENERAL DESIGN AND FUNCTIONAL CHARACTERISTICS:
Heat exchanger:
It is made of a welded steel sheet, easy accessible for cleaning and maintenance. It is made up of:
•
Combustion chamber
made of
AISI 430 STAINLESS STEEL,
with a low thermal load, with
ovoidal shape and suitable volume.
•
Patented,
modular
exchange elements
of
AISI 304 STAINLESS STEEL
, wide surface, with
whirlpooling marks and counter-current position, in order to optimize the thermal exchange. The
exchange elements are inclined to facilitate the drainage of combustion product condensate.
•
Exhaust manifold
of
AISI 304 STAINLESS STEEL
, with shutters for inspection.
Supporting frame:
The supporting frame is made of press-folded, powder-painted and galvanised steel.
The mitre joints are made of strong and die-cast aluminium and are fully designed by the Manufacturer.
Closing panels:
The closing panels are made of coated galvanised steel or of pre-coated sheets; they are thermally insulated
with a mineral fibre mat, and are provided with galvanised counter-panel sheets. These panels can be
removed to perform the ordinary internal inspection
.
Ventilation unit
The unit is made up of a centrifugal fan with backward blades and low noise emission and high efficiency;
they are powered by an electric motor connected by means of a belts and pulleys driven transmission
system, which provides this product with high reliability of the plant it is to be used with.
“LM”
safety thermostat:
The air treatment unit is equipped with a safety thermostat whose sensors is placed on the air outlet. It
stops the burner if the air is anomalously overheated. It has to be manually reset, after removing the cause
that has caused its intervention.
