TEH 20T and 30T devices are mobile, electrically operated air heaters.
They are used for air heating to heat rooms and speed up drying or deicing processes. The device can be used both inside and outside.
Thanks to the high fan power, large rooms can also be heated within
ashort period of time.
The integrated thermostat enables continuous temperature configuration
and ensures constant room temperatures.
The device is designed for operation under difficult conditions and can
also be operated at construction sites (heating and construction drying),
in greenhouses or other commercial fields e. g. for drying pottery.
The heater is designed for permanent operation.
Functional principle
Air to be heated is sucked in by the axial fan and fed through the interior
of the device. There, it passes a heating coil, is heated and released into
the room through the exhaust opening (refer to "Description of device")
