We started by supplying manual remote window openings to the construction industry. As time and technology moved on, we broadened our range to include electrical openings and smoke ventilation systems.
The majority of our electrical smoke and natural ventilation systems are manufactured in Hamburg by our partner D+H Mechatronic. For over 40 years D+H has repeatedly set the standard for safe, reliable ventilation systems improving comfort, safety and energy efficiency in over 100,000 buildings around the world.
