Smoke Control Damper

Rectangular sheet steel smoke control damper including ventilation function for the removal of smoke and heat in smoke extract systems, as well as for the controlled flow of the necessary supply air. Suitable as a support for keeping safety rooms and their anterooms smoke-free in pressurised ventilation systems (DBA), e.g., in fire brigade lift shafts or for smoke removal in escape tunnels.

• Can be used in discharge environments with elevated temperatures of up to 600 °C at tested smoke extract ducts and sheet steel ducts
• Meets pressure level 3 with any airflow direction and automatic release (AA)
• Nominal sizes 100 × 100 – 1250 × 2560 mm
• Volume flow rate of 360 m³/h or 100 l/s – 115110 m³/h or 31975 l/s at 10 m/s
• Design in sheet steel (also powder-coated according to RAL-CLASSIC chart) or stainless steel sheet in A4 quality
• According to EN 1751: Leakage air flow with closed damper at least class 2 and casing leakage air flow class B, from nominal sizes 840 × 480 leakage air flow with closed damper 3 and casing leakage air flow class C
• Integration into the central BMS with TROXNETCOM or with interface modules such as those in SLC^® technology
• C_mod for smoke extraction with ventilation function and control characteristics in combined systems (combination damper) and therefore pneumatic balancing possible via travel to intermediate positions

Rectangular smoke control dampers with ventilation function for heat and smoke exhaust with mechanical smoke extract systems, for the provision of additional supply air and for use in pressure differential systems

• CE-compliant smoke control damper according to EN 12101-8
• Meets the maximum possible performance characteristics for smoke control dampers according to classification standard EN 13501-4
• Use in load-bearing structures (solid and lightweight partition walls and ceiling slabs) to ensure fire integrity (fire compartmentation)
• For the ducts and shafts of heat and smoke exhaust systems.
• For pressure differential systems, mechanical smoke extract systems, gas extinguishing systems and for providing additional supply air
• Control input signal from the fire alarm system and integration into the central BMS with TROXNETCOM
• Remote signalling with open/close actuator and end position feedback
• C_mod = for smoke extract and ventilation in combined systems, which allows for pneumatic volume flow rate balancing as the damper blade can take intermediate positions
• Nominal sizes 200 × 200 – 1500 × 800 mm, for smoke gas flow rates up to 43200 m³/h or 12000 l/s at 10 m/s
• Low pressure losses with high upstream velocities, standard value of 10 m/s and above
• Automatic release (AA), option of manual override (MA)
• Simple and quick dry mortarless installation in solid and lightweight partition walls possible

Rectangular smoke control dampers with ventilation function, low installation depth and large cross section for heat and smoke exhaust with mechanical smoke extract systems, for the provision of additional supply air and for use in pressure differential systems

• Nominal sizes 200 × 230 – 1200 × 2030 mm, for smoke gas flow rates up to 29230 m³/h or 105235 m³/h at 12 m/s, upstream velocities up to 20 m/s possible 
• Simple and quick installation in and on components
• Casing, damper blades and actuator encasing made of calcium silicate
• Pressure level 2 (operating pressure -1000 to 500 Pa)
