Electric Heater WDH-IFH20

20 kW professional heating output for construction sites, workshops and commercial use | 400 V / 32 A

The WDH-IFH20 electric heater is a powerful electric fan heater for professional applications. With a heating output of up to 20 kW, an air circulation rate of approx. 3,084 m³/h and a robust metal construction, the unit is particularly suitable for construction sites, workshops, warehouses, cellars and larger commercial spaces.

The heating output can be selected in two stages: 10 kW or 20 kW. Additionally, it can be operated as a fan only, without the heating function. This makes the WDH-IFH20 flexibly applicable for heating and air circulation.

Important note on power connection:
The WDH-IFH20 requires a 400 V / 32 A CEE heavy-duty power connection. A supply cable is not included in the scope of delivery. An appropriately dimensioned connection cable is required for operation.

The main advantages of the WDH-IFH20

  • Up to 20 kW heating output – two heating stages with 10 kW and 20 kW.
  • High air circulation – up to approx. 3,084 m³/h for effective distribution of heated air.
  • Stepless thermostat – temperature control in the range of 0 to 40 °C.
  • Fan operation – can also be used for air circulation without the heating switched on.
  • Robust metal construction – for professional use in demanding environments.
  • Overheating protection – integrated safety function with reset option.
  • IP24 protection rating – for use under suitable conditions with protection against splash or drip water.
  • Memory function – after a power interruption, the device can resume the previously selected setting.
  • Mobile use – integrated carrying handles facilitate transport.

Electric heater for construction sites and commercial use

The WDH-IFH20 was developed for applications where high electrical heating output is required. With up to 20 kW of heating power, it is suitable for, for example, larger construction sites, workshops, storage areas and commercial spaces.

Since no combustion takes place in an electric heater, no exhaust gases are produced during the heating process. This makes electric heaters fundamentally interesting for areas where direct electrical heating without combustion is desired.

Ideal for targeted temperature control:
The WDH-IFH20 can be used to temper rooms during work, reduce the cooling down of areas, or warm the air during suitable drying tasks.

Support for building drying and water damage

Under suitable conditions, warm air can support the evaporation of moisture. Therefore, the WDH-IFH20 can also be used in combination with a suitable dehumidifier and good air circulation for building drying, renovation and drying after water damage.

For effective drying, the warm air should be distributed specifically in the room while simultaneously removing the resulting moisture from the room air using a powerful dehumidifier.

Flexible heating output with two heat settings

Depending on the heat demand, two heating stages can be chosen. A reduced heating output of 10 kW is available, while the second stage provides up to 20 kW.

In addition, the unit can be operated as a fan only. This allows the WDH-IFH20 to be used for air circulation even when no additional heat is needed.

Temperature control via mechanical thermostat

The integrated mechanical thermostat allows for stepless adjustment in the range of 0 to 40 °C. This allows the desired room temperature to be set according to the respective application.

The unit also features integrated overheating protection. If triggered, the safety function can be reset via the provided reset feature.

Areas of application

  • Construction sites: Heating and temperature control during construction and renovation work.
  • Workshops: Additional heat in large work areas.
  • Warehouses and commercial spaces: Assistance in temperature control for larger rooms.
  • Cellars: Suitable for applications requiring an electrical heat source.
  • Building drying: Combined with dehumidifiers to support moisture removal.
  • Frost protection: Can be used to temper suitable rooms to prevent severe cooling.
  • Air circulation: Operation without heating function is possible.
