Description of the device
The electric heater was designed as a robust, mobile unit also to
be positioned outdoors.
The device comes equipped with two lockable swivel castors (5)
and two trestle rollers (7) each. Forklift pockets and crane lugs
are attached to the housing as transport aids, enabling
convenient transport and space-saving storage by stacking up to
3 devices on top of each other.
The housing is designed as welded frame construction and
provided with partially removable steel sheet panels. The
electrical control box made of steel is mounted in horizontal
position, protected between the stacking handle bars on the
housing, and contains all switching devices, operating elements,
indicator lights, safety devices and the control unit. All steel and
sheet metal parts are galvanized and powder-coated.
The device is designed ready-to-install and comes with all the
electrical and mechanical components as well as safety
installations required for safe and functional operation.
To ensure safe transport and operation, the device is also
equipped with a shock protection frame.
Functioning principle
The air is taken in by the fan via the integrated bag filter (10) and
heated by means of the multi-stage electric heating. Four
different temperature levels can be selected between 0 and
100%. These are kept constant by the integrated controller with
the maximum outlet temperature being reduced to approx. 60 °C
(±5 °C).
Thanks to the two-stage fan operation a higher temperature
increase can be achieved by selecting the lower stage (approx.
2/3 of the nominal air volume). The integrated, electronically
controlled control unit with air volume flow measurement and
automatic rotational speed control of the fan ensures nearly
constant volumetric flow rates covering a wide load range (e.g.
for variable hose lengths).
The temperature increase refers to the sucked in air temperature
(usually the ambient temperature) and is increased according to
the preselection. The temperature sensors at air inlet and outlet
transmit the current temperature values to the control unit, which
then, depending on the demand, keeps the preselected
temperature increase constant by means of the control and
operation of individual heating elements or the entire heater.
