MASTER BV 471 is a highly efficient oil air heater with a heating capacity of 136 kW, dedicated to heating large facilities. Thanks to the combustion chamber with an exchanger, the heater provides clean and dry warm air to the room. Depending on the air outlet used, one, two or four pipes for hot air distribution can be connected to the device. The operation of the heater can be easily controlled by a mechanical or electronic thermostat installed inside the room.

The new fan has a higher pressure of 250 Pa, thanks to which 15 m long pipes for hot air distribution can be connected. The special shape of the fan housing significantly improves and stabilizes the air flow through the exchanger.

An additional burner housing protects against mechanical damage and air contamination. The degree of protection against electric shock for the housing is IP 55. If necessary, the housing can be easily removed.

The high strength and rigidity of the device structure is ensured by the steel frame and the use of screws with metric threads.

Possibility to adapt the device to work in different climates and at different altitudes thanks to digital control. The "Cold Start" switch enables the heater to be started at very low temperatures. The device also uses an integrated electronic control panel with a display and a counter of worked hours.

Easy and quick connection of fuel lines to the external fuel tank. Possibility of optional use of quick couplings of fuel lines

The new AIR-BUS series features an upper exhaust outlet and the possibility of using additional accessory chimney stabilizers.

As standard, the device has 4 handles for transport with a crane. Optionally, the heater can be equipped with handles to facilitate transport with a forklift.
