Smoke extraction drives (SHEV) that comply with the strictest safety requirements are a must. Corresponding legal standards regulate these requirements in many countries around the world. It's your choice! Many of our drives have been awarded internationally recognized accreditations and test certificates, such as VdS, TÜV, UL, NF, CNBOP, EN and ISO.

SHEV drives from D+H therefore satisfy the strictest demands in terms of safety. They excel with their elegant design and convenient set of functions.

Green building with D+H window drives
Simple and efficient, controlled natural ventilation can be provided using electrical window drives. Due to their high eco-credentials, architects and planners increasingly rely on this form of ventilation, especially for green building concepts in connection with accreditations like LEED or DGNB.

Special window drives for controlled natural ventilation can be integrated in a high-quality and modern overall design thanks to their own sophisticated design, whether surface mounted or integrated within the window frame so they are virtually invisible.
