Portable electric heater for construction sites, workshops, and halls up to approx. 450 m³
The Master B18EPR is a high-performance electric fan heater with 18 kW of heating power and an airflow of approx. 1700 m³/h. This electric heater is suitable for the mobile heating of construction sites, workshops, halls, and other work areas of up to approx. 180 m² or 450 m³.
The heating power can be adjusted via the rotary knob in three operating modes: ventilation only, 9 kW, or 18 kW. This allows the Master B18EPR to be flexibly adapted to the respective heating requirements.
The Master B18EPR electric heater is particularly suitable for areas where heat is required quickly and flexibly. With a heating capacity of 18 kW, the unit can be used, for example, on construction sites, in workshops, or in larger work and hall areas.
Since the Master B18EPR is electrically operated, it does not require fuel such as diesel, heating oil, or gas. The electrical heating power can be selected directly via the rotary knob on the device.
The Master B18EPR has three operating modes. In addition to ventilation only, 9 kW and 18 kW heating power are available.
| Operating mode | Function |
|---|---|
| Ventilation | Ventilation mode only with no heating power. |
| 9 kW | Reduced heating power for lower heat requirements. |
| 18 kW | Full heating power for maximum heat output. |
The desired operating mode is easily selected via the rotary knob on the device.
With an airflow of approx. 1700 m³/h, the Master B18EPR distributes the heated air throughout the room. This makes the fan heater suitable for larger work areas and rooms up to approx. 450 m³.
The specified operating range is up to approximately 180 m² or 450 m³. The actual achievable room temperature depends on, among other factors, room size, insulation, outside temperature, and building heat losses.
The Master B18EPR is operated with 400 V / 50 Hz and features a CEE 32 A plug. A correspondingly suitable power connection is therefore required for operation.
The maximum fuse rating is specified at 32 A. Before connection, ensure that the existing electrical installation is suitable for operating the device.
An optional Master TH5 room thermostat is available for the Master B18EPR. The stepless rotary dial allows settings between 0 and 36 °C. The room thermostat is plugged directly into the fan heater.
Also optional is a warm air hose with a length of 7.6 m and a diameter of 305 mm. This allows the warm air to be directed more precisely.
The Master B18EPR can be used in various areas where powerful electric heating is needed.
