In detail

Maintenance by the book — without surprises

Smoke and heat exhaust ventilation systems (RWA, "Rauch- und Wärmeabzugsanlagen") are safety-critical equipment. Owners and operators are legally required to have them serviced and inspected each year by a qualified company.

We carry out annual maintenance on your systems regardless of the original manufacturer. This includes visual inspection, function test, trial run and servicing of moving parts. Wear items are replaced directly on site where stock allows.

What you receive from us

  • A single point of contact for the entire season
  • Service dates coordinated with your property manager or facility manager
  • Written documentation with photo evidence for fire inspections and insurance
  • A ready-to-act remediation plan for any defects we identify

Standards we work to

We work to DIN 18232 (smoke and heat exhaust ventilation), DIN EN 12101 (components of smoke and heat exhaust systems) and the requirements of the applicable state building code.
