In the high-density urban landscape of Kuala Lumpur and Selangor, Emergency Smoke Control Ducts are the primary arteries of a building’s life-safety system. Unlike standard HVAC ducting, these are engineered to operate under extreme thermal stress to extract toxic, superheated gases from a fire zone while maintaining clear, breathable air in evacuation routes.
EKG M&E Sdn Bhd specializes in the design and installation of fire-rated ductwork that ensures your building remains BOMBA compliant and adheres to the MS 1780 code of practice for smoke control.
Smoke control ducts are subjected to temperatures that would melt or buckle standard air-conditioning conduits. Their construction must meet three specific survival criteria:
Under UBBL and BOMBA regulations, smoke control ducts must provide a minimum of 2 hours of fire resistance.
Integrity: The duct must not collapse or allow flames to pass through, ensuring smoke is contained within the system.
Insulation: The external surface temperature of the duct must remain low enough to prevent the "auto-ignition" of combustible materials in adjacent rooms.
EKG Solution: We utilize heavy-gauge 1.2mm galvanized steel encased in certified fire-rated boards or high-density mineral wool wraps.
When exposed to fire, metal ducts expand rapidly. If not engineered correctly, this expansion can destroy wall seals or buckle the duct.
Reinforced Hangers: We install seismic-rated and fire-resistant support systems that accommodate thermal movement without losing structural stability.
Intumescent Sealing: Every wall penetration is treated with BOMBA-approved intumescent fire stopping that expands under heat to maintain a hermetic seal between fire compartments.
As a BOMBA-Compliant M&E Specialist, EKG ensures your emergency infrastructure supports building efficiency:
TNB Energy Efficiency (Lower Static Loss): Leaky smoke ducts force extraction fans to work harder. By ensuring a Class C Airtight installation, we minimize static pressure loss. This allows your Variable Frequency Drive (VFD) to run at lower frequencies (Hz) during mandatory weekly testing, directly resulting in a lower monthly TNB electricity bill.
EECA 2024 & Building Compliance: Under the Energy Efficiency and Conservation Act (EECA) 2024, mechanical air transport must be optimized. Our precision-sealed fire ducts prevent the waste of conditioned air during normal operations, protecting your Building Energy Index (BEI).
High-Temperature Fan Synergy: Our ducting is designed to work in tandem with high-temperature smoke extraction fans (rated for 250°C to 400°C). We ensure that the duct-to-fan connections utilize certified fire-rated flexible connectors to prevent vibration transfer while maintaining fire integrity.
Total 3D BIM Coordination: Smoke control ducts are often the largest conduits in a building. We utilize 3D modeling to route these heavy ducts through crowded ceiling voids with zero "clashes" against sprinklers or structural beams.
Turnkey BOMBA Submission: We perform the mandatory Smoke Tests and Anemometer Airflow Traverse required for your Fire Certificate (FC) application and annual renewals.
Precision Balancing: We install multi-blade volume control dampers to ensure that extraction is balanced across all zones, preventing "smoke stagnation" in dead-end corridors.
