Specification

u003cpu003eFlamgard Calidair’s tunnel dampers are rigidly designed and are used to regulate the airflow in transit tunnels. They ensure that the air that is circulating through the tunnel is safe for passenger transit, without excessive build-up of exhaust gases. In normal conditions, tunnel dampers control the volumetric air flow in a transit tunnel.u003c/pu003enu003cpu003eIn emergency fire conditions, it is essential that the dampers are there not only for ventilation, but to regulate the fire and the associated smoke and hot gases. Fires in tunnels generate severe smoke which, if not reliably ventilated, could cause those in the tunnel to suffer the life-threatening effects of smoke inhalation. Tunnel dampers can be used in emergency conditions to operate to extract these toxic fumes and smoke away from the critical area as well as providing a fire barrier when closedu003c/pu003enu003cpu003eHighly customisable controls configurations to enable optimised damper free area to ensure best use of tight site conditions, improving air flow and minimising pressure drop. Actuator locations can also be modified to achieve best accessibility for easy of commissioning and maintenance.u003c/pu003en

Operation Principle

u003cpu003eThe CFD-02TM dampers utilize a parallel or opposed linkage system to open and close the damper units and can be normally open or normally closed depending upon the requirement. The airflow through the Flamgard Calidair damper is bi-directional and the orientation can be vertical or horizontal.u003c/pu003en

Installation

u003culu003enu003cliu003eSuitable clamps and wall anchors should be used to support the damper to the concrete surface.u003c/liu003enu003cliu003eThe wall anchors (bolts) and wall clamps are to be suitable to support the weight of the damper and for the mounting surface. They should also be suitable for the site conditions and location and design limits for high temperature applications. As a guide, wall clamps and anchors are to be at 200mm spacing around the damper mounting flange. The wall anchor bolts are to be installed as per manufacturers guidelines and set at the correct distance from the concrete opening.u003c/liu003enu003cliu003eWhen mounting to a concrete surface, dampers cannot be ‘hung’ from the ceiling. For vertical or horizontal mounting to concrete surfaces.u003c/liu003enu003cliu003eGasket, suitable for the high temperature and leakage requirements, should be installed between the mounting surface and the damper to provide a seal.u003c/liu003enu003cliu003eThe joining plates to join modular dampers are supplied for direct mounting to the flanges of the damper. These can be sealed after damper assembly using suitable fire rated sealant to enhance the leakage performance.u003c/liu003enu003cliu003eIf the actuators are off-set from the damper, on a pantograph arrangement, an angle bracket is fitted to allow clamping of the pantograph to the wall/floor and to add support for the off-set weight of the actuator.u003c/liu003enu003cliu003eThe damper flanges are extended on each corner of damper assembly to provide a direct fixation of the damper at each corner to the wall. This provides additional support and also aids with installation.u003c/liu003enu003c/ulu003enu003cpu003eu003cimg loading=u0022lazyu0022 decoding=u0022asyncu0022 class=u0022alignnone size-full wp-image-50357u0022 src=u0022https://www.halton.com/wp-content/uploads/2021/03/CFD-02TM-Installation.pngu0022 alt=u0022u0022 width=u0022942u0022 height=u0022642u0022 srcset=u0022https://www.halton.com/app/uploads/2021/03/CFD-02TM-Installation.png 942w, https://www.halton.com/app/uploads/2021/03/CFD-02TM-Installation-768×523.png 768w, https://www.halton.com/app/uploads/2021/03/CFD-02TM-Installation-10×7.png 10w, https://www.halton.com/app/uploads/2021/03/CFD-02TM-Installation-450×307.png 450w, https://www.halton.com/app/uploads/2021/03/CFD-02TM-Installation-800×545.png 800wu0022 sizes=u0022(max-width: 942px) 100vw, 942pxu0022 /u003eu003c/pu003en
