PKI-R

 

PKI-R

The PKI-R circular fire damper is a fire shutter of HVAC ducts. The damper blade closes the HVAC duct on the basis of a mechanical, thermal or electric impulse and therefore prevents fire, heat and smoke from spreading. The fire damper is certified in compliance with EN 15650, tested in compliance with EN 1366-2 and classified in compliance with EN 13501-3.

The fire damper housing and auxiliary structures are made of galvanized steel sheet. On request, it is possible to deliver the construction and housing made of stainless steel sheet A316L or A304.

Circular fire damper with release mechanism

ZV - The basic equipment of the circular fire damper (standard model) is a manual mechanism with a trigger spring. The spring is released when the fuse is disconnected as the temperature reaches 72°C (100°C on request). The damper closes within 10 s after the fuse has been disconnected.

DV1-2 ZV + two limit switches signalling the damper position „OPEN“ and „CLOSED“, 24 V (AC/DC) / 230 V (AC)

DV5-2 ZV + pulse electromagnetic release mechanism 24 V (AC) + two limit switches signalling the damper position „OPEN“ and „CLOSED“. The damper closes when the electric pulse gets in the electromagnet and it gets energized.

DV6-2 ZV + pulse electromagnetic release mechanism 230 V (AC) + two limit switches signalling the damper position „OPEN“ and „CLOSED“. The damper closes when the electric pulse gets in the electromagnet and it gets energized.

Circular fire damper with servo drive

The DV7-T or G7-T circular fire damper with the servo drive Belimo (DV) or Gruner (G) 230 V (AC) equipped with a spring and with a thermoelectric release sensor. Auxiliary switches signalling the damper blade position are part of the servo drive.

The DV9-T or G9-T fire damper with the servo drive Belimo (DV) or (G) Gruner 24 V (AC/DC) equipped with a spring and with a thermoelectric release sensor. Auxiliary switches signalling the damper blade position are part of the servo drive.

The DV9-T-ST or G9-T-ST fire damper with the servo drive Belimo (DV) or Gruner (G) 24 V (AC/DC) equipped with a spring, with a thermoelectric release sensor and with the communication unit Belimo BKN230-24 or Gruner fs-UFC24-2 (other communication units on request). Auxiliary switches signalling the damper blade position are part of the servo drive.

The DV9-T-W or G9-T-W fire damper with the servo drive Belimo (DV) or (G) Gruner 24 V (AC/DC) equipped with a spring and with a thermoelectric release sensor. The damper is equipped with cables for connection with the communication unit. Auxiliary switches signalling the damper blade position are part of the servo drive.

The DV9-T-SR or G9-T-SR fire damper with the servo drive Belimo (DV) or (G) Gruner 24 V (AC/DC) equipped with a spring, control 0-10V and with a thermoelectric release sensor. Auxiliary switches signalling the damper blade position are part of the servo drive*. This type of release mechanism is only available for dampers with DN ≥ 160 mm or H ≥ 160 mm. *) The power supply circuit is interrupted and the servo drive closes the damper within 20 s.
