fire dampers: round dampers
KTS
KTS fire dampers are designed for installation in ventilation installations as shut-off divisions, separating the zone covered by fire from the rest of the building.
KTS dampers can be used as a mixed ventilation function. They are designed for horizontal installation (in walls) and vertical (ceilings). They can be installed in all types of building partitions (rigid partitions), including drywall walls.
types of flaps:
– KTS-O-S – fire damper for ventilation ducts (normally open) with spring drive without comfort function.
–KTS-O-SE – fire damper for ventilation ducts with spring drive or with mounted actuator BL24-48 SMY / BL110-230 SMY, with separation of safety function from comfort function. The comfort function enables remote opening of the damper (arming) – this is done by installing the actuator.
– KTS-O-E – fire damper for ventilation ducts with actuators with return spring, with combined safety function and comfort function. In the case of these flaps, the drive system is an electric actuator of the BLF or BF series by BELIMO, series 229 or 239 by GRUNER or GNA or GGA by SIEMENS
