Problems with fire protection dampers for ambient air units within conveyor processes:
The closing element, which is permanently in the conveyor stream, can be damaged or contaminated by abrasive goods being transported through the conveyor system. Therefore a reliable closure of the system in case of fire can not be assured. When transporting sustained fibres through the conveyor some of this fibres get stuck and deposit at the dampers blade, so that the closing process is inhibited.
Function
The tube connector is pulled back and the closure seals the opening.
Customer benefits
Release by fire detection elements
During use, connection pipes and pipe liner are congruent - therefore no sedimentation occurs
T90 according to DIN 4102-5,EI2 90 / EI1 120 according to EN 13501-2 We also offer a fast closing in split second due to special pneumatic installations
Applicable for over- and under pressure, always clean by using compatible sealings
Usable for various conveyor goods, e.g. cardboard and paper stripes
