Master B 5 EPB Electric Heater – 5 kW Heating Power, 400 Volt
The Master B 5 EPB electric heater is a robust, portable electric fan heater with adjustable heating power of 2.5 or 5 kW. It is ideal for temporary heating in workshops, construction sites, storage areas and commercial premises. With an airflow capacity of 510 m³/h, the unit efficiently distributes warm air throughout the room.
Important electrical connection information: The Master B 5 EPB requires a 400 V three-phase power supply (16 A, 5-pin). The unit cannot be operated using a standard 230 V household socket. Before purchasing, please ensure that a suitable electrical connection is available at the intended location.
Powerful Electric Heating for Versatile Applications
The Master B 5 EPB offers two selectable heating outputs of 2.5 and 5 kW, as well as a separate fan-only mode without heating. The integrated room thermostat allows the desired temperature to be adjusted between 5 and 35 °C.
As heat is generated electrically, no combustion exhaust gases are produced during operation. This makes the fan heater particularly suitable for applications requiring a portable, emission-free heat source at the point of use.
Key Benefits of the Master B 5 EPB
- Up to 5 kW heating power: Two heating settings of 2.5 and 5 kW for flexible heating performance.
- 400 V three-phase operation: Requires a suitable 16 A, 5-pin electrical connection.
- High airflow capacity: 510 m³/h for effective distribution of warm air.
- Integrated room thermostat: Adjustable temperature range from 5 to 35 °C.
- Separate fan-only mode: Air circulation without activating the heating elements.
- Robust construction: Durable steel housing designed for portable commercial use.
- Overheating protection: Equipped with an overheat thermostat and thermal motor protection.
- Exhaust-free heating: No open flames or combustion exhaust gases during operation.
Ideal for Workshops, Construction Sites and Commercial Use
Thanks to its compact design and weight of just 6.4 kg, the Master B 5 EPB can easily be moved between different locations. Typical applications include workshops, agricultural facilities, construction sites and commercial premises.
For applications requiring lower heating output, the Master B-2PTC electric heater offers an alternative. The Master B 5 EPB, on the other hand, provides up to 5 kW of heating power and explicitly requires a suitable 400 V three-phase connection.
