Information about the device

Device description

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 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.
