The small size NBC contribution with tripartite glazing combines unique aesthetics and exceptional usable properties . In addition to visual values, the device guarantees efficient space heating and ecological wood burning . Thanks to the use of modern materials and innovative technical solutions, it is characterized by very good technical parameters. One of its many advantages is the possibility of connecting the air intake from the outside . The elegance of the insert is added by decorative glass glazing . In addition, it has a child lock , protecting against unauthorized opening of the door.



The contribution ensures the safety of use, because it has so-called child lock, protecting against unauthorized opening of the door.

The front of the insert is equipped with heat-resistant ceramics that withstand temperatures up to 800 ° C. The attached glass has a quality and safety certificate.

The body and the front of the insert are resistant to high temperatures due to the use of high-quality steel.

The door frame is made of a closed profile, which makes them stable and resistant to stresses occurring during operation at high temperatures. The excellent tightness of the insert is guaranteed by the solid welds made in the noble gas shield. Steel elements cut with laser cutters and then bent on CNC bending machines.


The device meets the requirements of Ecoprojekt and BImSchV 2 , which sets the maximum CO emission.


NBC draws attention with its modern design and aesthetics of finishing. It impresses with a harmonious vision of fire, giving the interior a unique style. The heat radiates not only from the front, but also from the sides.

The fireplace is equipped with a single, decorative glass window, thanks to which it looks elegant and modern. The use of this solution visually enlarges the front of the cartridge and emphasizes the vision of fire.

The door of the cartridge has a convenient railing, which makes it easier to open the door up.


The door of the cartridge works in the lift up system – the window is lifted up. This system was built based on the counterweight – steel cable blocks work on the bearings, up to 4 (2 per side), thanks to which the weight of the door is distributed evenly. They move along the sliding guides installed in the frame, which guarantees their light, quiet and trouble-free operation. A large amount of wood can be loaded at once by lifting and lowering the door. Additional mechanism, enabling both sides – side opening of the glass, which facilitates their cleaning.

The device is additionally equipped with a clean glass system – thanks to the so-called the air curtain is spread evenly, sweeps the glass and minimizes the deposition of soot on it. This allows you to maintain the effective and clean look of the glass for a long time.

The fireplace uses a specially profiled bottom plate made of Acumotte, thanks to which the combustion chamber is deeper and contains more wood, and the log does not fly on the glass.

Keeping the cartridge clean is easier thanks to the mounted grate and the container in which ash accumulates.


The more efficient combustion and longer temperature maintenance is due to the lining of the Acumotte combustion chamber, a heat accumulating material that increases the temperature in the furnace. In addition, its smooth, white surface looks impressive inside the fireplace.

Afterburning of fuel particles takes place thanks to the deflector, which extends the exhaust path, and the secondary aeration system. This process also increases the efficiency of combustion and guarantees better use of energy, and thus minimizes the emission of harmful substances into the atmosphere.

The device has a triple ventilation system for the combustion chamber, thanks to which wood burning in the cartridge is ecological and most importantly economical.

The primary air is supplied to the cartridge from the outside, thanks to the built-in 125 mm air inlet connection. The air intake stub is located in the floor of the cartridge. Its regulation takes place by means of a built-in throttle, which is set by one regulator, located below the door, which excludes errors in improper use. The whole mechanism works very quietly and without failure.


The NBC model meets the Ecodesign standards and the requirements of the restrictive BImSchV 2 standard, which sets the maximum CO emission.
