5. OPERATING PRINCIPLE
The EL 4 electric heater is a mobile appliance used for heating ambient air. For improved heating,
thawing or drying of spaces, this area should be closed.
The built-in thermostat allows regulation to a constant ambient temperature.
Operating principles
The air to be heated is drawn through an axial fan and subsequently flows through the interior of
the appliance. It is warmed by flowing past a heating element. This air is then expelled by the air
outlet panel into the environment (see description).
The EL 4 electric heater has been designed and developed for professional use and is therefore
suitable for use in locations that are under construction or for heating and drying buildings,
greenhouses or other industrial areas.
The heater may be used to be in continuous operation.
6. APPLICATION
The EL 4 electric heater is designed for heating and air ventilation, and may be used indoors. It is
used for drying, thawing, heating or simply for ventilation.
For example, the appliance may be used to heat rooms, cellars, greenhouses and construction sites,
or to thaw machinery or pipelines.
