described in detail.

(3) Application / fields of operation

The main purpose of the DE 20 SH unit is to heat changing working places. In this respect, the unit is
used to heat rooms or materials.
DE 20 SH produces very high air temperatures which are suitable for the following processes:

For pest control

For curing synthetic material (tempering)

Process heat for industrial requirements

Drying of heat-resistant materials
ATTENTION: The DE heater units must not be used in potentially explosive environments.
Design: In order to determine heat requirement of rooms or buildings, the website www.heylo.de as
well as www.waermebedarfsrechner.de provides you with a calculator free of charge. In addition, the
heat requirement can be calculated by using the following formula:
thermal insulation
without thermal
insulation
with insulation
Circulating air operation: The electric heaters are not intended for operation with circulating air.
Internally the motor has been fitted with an over-temperature protection which switches the motor off in
case of ambient temperatures of over 60 deg. C. High intake air temperatures are possible in case of
operation with circulating air. This will result in the STB being triggered.
Hose operation:
A high-temperature hot air hose can be connected to the DE 20 SH unit. The maximum hose length is
limited to 7.6 m. Please ensure that the hose is laid as straight as possible. Many bends or a jammed
hose may also trigger the over-temperature protection in the unit.
Heating operation:
In heating mode, the units have to be set up safely; during the operation the units must not be able to
be able to wobble or topple over. The outlet side must have a distance to inflammable materials as
rendered in the setup guidelines (chapt. (4)). The ambient temperature must not exceed 60 deg. C.
