Drives for smoke extraction and ventilation

Our chain drives ensure smoke exhaust and safety

The SHEV systems from D+H ensure safe smoke and heat exhaust ventilation and guarantee smoke extraction from stairwells or lifts. Our CDC Series chain drives can be integrated perfectly into window profiles. They are virtually hidden in façades and roof windows and installation is quick and easy. Powerful and fast: Our rack and pinion drives have an opening speed of only 60 seconds in an emergency. Window locking drives provide the best burglary protection. Our skylight systems and louvre drives are tested and approved in accordance with the NSHEV standard (natural smoke and heat exhaust ventilator) DIN EN 12101-2. We are available for consultation and will calculate the geometric and aerodynamic smoke extraction.

Drives can also be used for controlled natural ventilation

Nearly all drives from D+H can be supplied with both an output voltage of 24 V and 230 V and feature BSY+ synchronous control. Interaction between the SHEV control panel and the SHEV drive is possible thanks to the new bus communication, Advanced Communication Bus (ACB). In addition to NSHEV-certified products, D+H also produces solutions for controlled natural ventilation in accordance with DIN 1946-6. Our VCD Series, which we recommend for use in façade windows, roof windows and ventilation flaps, has been specially developed for controlled natural ventilation. The BDT Series is also exclusively responsible for ventilation and cross ventilation. The fitting drive opens window sashes evenly on all sides. This parallel opening makes gap ventilation of up to 6 mm possible.
