Gas heater with burner designed for indoor installation, available in 15 versions with heating capacities ranging from 21 to 73,6 kW. Heater is available in versions for installation on the wall, under the ceiling and with axial or radial fan.

Units with axial fan (Robur F and FV) ensure high efficiency. Burner made of stainless steel reaches 91 % of efficiency and reduces NOx emission.

Radial fan applied in Robur FC units makes it possible to combine the unit with air duct installation, which allows to distribute warm air into the selected areas of the room. Application of the mixing chamber ensures air exchange in heated room.

Combustion chamber ensures safety and long, reliable operation due to assembly with exchangers without welding.

The heaters have as a standard a summer/winter operating mode switch with integrated signalling and alarm reset.

There are various types of chimney packages recommended for the heaters – horizontal, vertical, concentric and separate. There are also available various elevation endings – protective caps.


The F series heaters are designed for heating various types of buildings like warehouses, supermarkets, industrial buildings, workshops etc.


The heaters have as a standard equipment an operating mode switch summer/winter with integrated signalling and alarm reset and a set of nozzles for liquid gas.


Construction – burner made of stainless steel is controlled by advanced control system and thanks to this reduces almost entirely CO and NOx emission.

The floor effect, which is achieved through the special design of the heat exchanger, allows to keep effectively the warm air in the zone occupied by the people and avoid significant temperature stratification in the room.
