Design and function
3.1 Unit description
The units are portable electric heating units for
industrial applications. The units are operated
exclusively with electric power and have been
designed in such a way that they can be used fully
automatically, universally and in a straightforward
manner.
The units are equipped with specially enclosed
electric heating resistors, a low noise and low-
maintenance radial fan, a safety and aftercooler
thermostat, an integrated room thermostat and a
power cable with protective contact plug.
The units conform to the fundamental health and
safety requirements of the appropriate EU regula-
tions.
The units are dependable and offer ease of opera-
tion.
Locations at which units are used
The units are designed exclusively for commercial
use.
The units may be used among other things for
the following:
n
Drying newly completed buildings
n
Spot heating outdoor workspaces or fire-proof
manufacturing facilities and halls
n
Continuous or temporary room heating
n
De-icing machines, vehicles and non-combus-
tible warehoused goods while adhering to the
relevant safety distances
Operating sequence
The units can be used in the respective modes for
air heating and air circulation purposes.
They can be operated on three heating settings
and one fan setting. They have a 5-stage operating
switch with the functions:
Off (0)
Ventilation (1)
Heating (2-4)
The unit is equipped with an integrated thermostat
to ensure that the room temperature is constant.
Once the selected temperature has been reached,
the thermostat stops the heating operation. If the
room temperature falls below the selected temper-
ature, the thermostat starts up the heating opera-
tion again.
The integrated thermal cut-out switches off the unit
if the temperature is excessively high and switches
it on again automatically after it has cooled down.
After switching off the units via the operating
switch or the room thermostats, the supply air
fan runs to cool the heating resistors for a cer-
tain time and then switches off automatically.
For optimum operation the units should not be
operated above an ambient temperature of
25 °C.
