Franzen Retrofit smoke control system
Franzen retrofit smoke control system
The retrofit smoke protection system is an exclusive development of Theo Schröders Entwicklung und Beratung GmbH, and Franzen has been successfully offering this system as a licence holder for many years.
For the first time, the system offers the possibility of retrofitting smoke protection to existing doors. These may, for example, be fire doors made of wood or steel. The system can be offered for both single and double-leaf doors.
Patented smoke control seals
The smoke control system for retrofitting existing doors with the patented circumferential smoke control seals "System Schröders" have been tested by the North Rhine-Westphalia Materials Testing Office in smoke and endurance tests.
The result of these approved tests is that the retrofitted doors fulfil the requirements of DIN 18095 and EN 1634-3.
