BEIRENS designs, manufactures and installs smoke flues (or exhaust ducts) for all types of generators: boilers, motors, turbines, ovens and fans.
We deploy two technologies: welded and modular (single and double-wall).

BEIRENS exhausts are designed to reduce pressure losses, optimise flue draught and evacuation of condensation. The number of cantings is optimized and the 45° angles are favoured
