Certified Fire Dampers

Product description

According to the newest revisions of SOLAS and IMO regulations we have developed and certified a new generation of fire-dampers. Almost every fire-damper in use today is only classified as a normal shut-off-damper, which are no longer allowded to be used for this application. Below you find the description of our standard-program for certified firedampers. A very flexible production allows special requirements to be met as well.
