Anodized aluminum Smoke and Heat Exhaust Ventilation System CDH-F

smoke and heat extractor

CDH-F Smoke and Heat Exhaust Louvre is designed for both daily ventilation and smoke exhaust in case of a fire. The Louvre Lamellas can be opened and closed by an electric actuator. CDH-F Smoke and Heat Exhaust Louvre is equipped with the lamellas that can be moved by an electric actuator. The anodized aluminum profiles and the insert mounted between the profiles and protected with a glazing gasket compose the lamellas. The S type Louvre lamella insert is made up of the polycarbonate sheets 20 mm in thickness. The A type Louvre lamella insert is made up of the mineral wool 20 mm in thickness inside and the aluminum sheet outside. The Louvre has the aluminum frame powder coated in the RAL9006 colour. CDH-F-L type Smoke and Heat Exhaust Louvre is equipped with a measuring device and wire mesh. This type Louvre has a differential pressure transducer with ø6 copper tubes as well. The Belimo electric actuators open/close the lamellas and provide desired air flow rate by adjusting the position of the lamellas. The power supply is 24 V AC/DC or 230 V AC. When the power supply is lost, the Louvre Lamellas are opened if a return spring actuator is used in the CDH-F Smoke and Heat Exhaust Louvre.
