When the system goes down

A faulty smoke vent system is more than a technical problem — it's a liability. We analyse the fault on site, document the finding and bring the installation back to a compliant state.

Even older systems whose manufacturers no longer exist can in many cases be kept running with compatible spare parts. Where that is no longer economical, we recommend targeted replacement of individual components, not blanket replacement on suspicion.

Typical repair scenarios

Pneumatic and electric drives no longer functioning
Defective release groups, manual push-buttons, smoke detectors
Damaged skylights, leaking smoke vent flaps
Control panels without power or with persistent fault state

24-hour hotline

For safety-critical failures (e.g. a vent that won't open in stairwells or industrial halls) we are on site within 24 hours on weekdays.
