Once a year mandatory: functional test of fire dampers in HVAC systems in accordance with the applicable proofs of usability and operator rules VDI 6022. We test release, run, closing force, clean blade and seals, document with protocol and barcode history.
Fire dampers in HVAC ducts must prevent fire and smoke transmission to other compartments in case of fire. Every damper is a safety-critical part — the operator is legally required (BauO, MLüAR) to have function tested annually by a specialist. applicable proof of usability defines scope, intervals, documentation; VDI 6022 covers hygiene.
Which variant fits depends on the installation context, the existing building and the fire-protection concept — we advise per project.
Cost-efficient solution for the most common installation contexts — tested systems from established manufacturers.
For non-standard sizes, installation contexts or higher requirements driven by the fire-protection concept or expert reports.
Recertification of existing components or phased replacement — coordinated around live operations.
All prices excl. VAT. Maintenance contracts are quoted on a per-unit basis.
We cover every typical building type — from residential to industrial complexes with hundreds of components per site.
Apartment buildings, stairwells, transitions to boiler rooms and underground garages — usually with smoke-protection properties.
Separation of production, storage and administration plus protection of mechanically loaded plant.
Schools, hospitals and administrative buildings under NRW special-buildings regulations — often combined with hold-open systems.
European product standard — scope, intervals, documentation.
Fire-resistance class by integrity (E) and insulation (I).
Regional implementation (LüAR NRW) for HVAC through compartments.
Adds hygiene inspection and cleaning needs to fire testing.
NRW-wide, exclusively with our own installers — no subcontractors.
Aachen to Bielefeld, Lower Rhine to Sauerland — survey usually within five working days.
No subcontractors. Warranty work and maintenance always trace back to the same people.
We schedule appointments proactively. Inspection record for the fire authority comes with every visit.
Check layouts, identify dampers, document access, flag missing inspection ports.
Manual and automatic release, run time, limit positions, reset. Check drive type (spring return, motor, BSKI).
Remove dust, grease, corrosion from blade and seal. Re-set release force and closing sequence.
Digital protocol with photo, damper ID, condition, deficiencies. Export for inspector and insurer.
We handle annual functional test, cleaning and documentation — optionally with dedicated contact and 24h response.
