PKI-S

 

PKI-S

The fire four-sided damper PKI-S is a fire shutter component in the ventilation duct. The blade of the fire damper closes up the four-sided ventilation duct based on a mechanical, thermal or electric signal and therefore stops fire, heat and fumes from spreading. The fire dampers are certified in compliance with EN 15650, tested in compliance with EN 1366-2 and classified in compliance with EN 13501-3. The housing and the auxiliary constructions of the fire damper are made of galvanized steel sheet. The construction and the housing can be made-to-order from stainless steel sheet A316L or A304.

The blade of the fire damper PKI-S is composed of calcium silicate asbestos-free plates and is placed in a protective frame of the damper. The passive tightness of the fire damper stopping fumes from spreading is provided by a gum elastic gasket. The active tightness stopping fumes and heat from spreading during fire is provided by the anti-fire gasket Intumex. In order to set the damper in the position „CLOSED“, the dampers are equipped with a release mechanism „Manual“ - basic implementation with a fuse, alternatively with an electromagnet or with a servo drive. The panel of the release mechanism of all the fire dampers is removable and also interchangeable with a differently equipped panel, e.g. with a servo drive mechanism instead of the manual control mechanism etc. All the fire dampers are equipped with at least one inspection opening.

Manual release mechanism

ZV standard equipment of the fire damper (standard model) is equipped with a manual mechanism with a release spring. The spring is released after disengaging of the fuse as the temperature reaches 72 - 74°C (can be 100°C on request). The damper closes up within 10 sec after disengaging of the fuse.
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 as an electric impulse gets into 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 as an electric impulse gets into the electromagnet and it gets energized.

Servo drive release mechanism

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

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

The fire damper DV9-T-ST or G9-T-ST 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 can be made-to-order on request). As a part of the servo drive there are auxiliary switches signalling the position of the damper blade*.

The fire damper DV9-T-W or G9-T-W 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 the connection with the communication unit. As a part of the servo drive there are auxiliary switches signalling the position of the damper blade*.

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