VdS approval of Installers of Smoke and Heat Exhaust Ventilation Systems

VdS offers an approval for companies who are able to plan and install smoke and heat exhaust ventilation systems according to VdS CEA 4020 or DIN 18232-2.

The approval applies to one or more VdS-recognized smoke and heat exhaust ventilation systems. An initial approval is issued for a period of 18 months (so-called provisional approval); the final approval is issued for a period of four years. 

Smoke is a very difficult problem in the event of a fire; only smoke and heat exhaust ventilation systems with VdS-approved components and systems offer optimum protection
