In the vertical high-rise landscape of Kuala Lumpur and Selangor, the emergency escape stairwell is the most critical survival zone. Staircase Pressurization Ducting is an active fire life-safety system designed to inject fresh air into escape routes, creating a high-pressure shield that physically prevents toxic smoke from entering the stairwell.
EKG M&E Sdn Bhd specializes in the engineering and installation of these systems, ensuring they remain 100% operational during a fire to meet the strict mandates of the Uniform Building By-Laws (UBBL) and BOMBA standards.
The primary goal of this system is to maintain a higher air pressure inside the stairwell than in the adjacent floor areas (typically a pressure differential of 50 Pa).
For the system to work during an emergency, the ductwork must deliver a precise volume of air without leakage, even when exposed to high heat.
Fire-Rated Protection: Since these ducts often travel through multiple "fire compartments" to reach the stairwell, they must be fire-rated for 2 hours (FRL 120/120/120). This ensures that even if a fire occurs on an intermediate floor, the duct remains intact to deliver fresh air to the floors above.
High-Pressure Construction: Unlike standard comfort cooling, these ducts are built to withstand higher internal static pressures to ensure air reaches the furthest discharge points in a high-rise tower.
Pressurization Fans: Usually located on the roof or at the ground level, these fans activate automatically when the building's fire alarm or smoke detectors are triggered.
Barometric Relief Dampers: To prevent the stairwell from becoming over-pressurized (which would make it physically difficult for elderly or young occupants to open the heavy fire doors), we integrate relief dampers that bleed off excess pressure.
Intumescent Sealing: Every joint and wall penetration is sealed with BOMBA-approved intumescent materials that expand under heat to maintain the airtight and fire-proof integrity of the system.
As a BOMBA-Compliant M&E Specialist, EKG ensures your pressurization infrastructure supports building efficiency:
TNB Energy Efficiency (Dual-Purpose Optimization):
In some designs, these ducts provide daily fresh air ventilation. By ensuring the network is Class C Airtight, we minimize static pressure loss. This allows your Variable Frequency Drive (VFD) to maintain airflows at lower frequencies (Hz) during normal operation, resulting in a lower monthly TNB electricity bill.
EECA 2024 & Building Compliance:
Under the Energy Efficiency and Conservation Act (EECA) 2024, efficient mechanical transport is a core requirement. Our precision-sealed fire ducts prevent the waste of conditioned air into unconditioned ceiling voids, protecting your Building Energy Index (BEI).
The "Golden Hour" for Evacuation:
By keeping the stairwell clear of smoke, our systems provide the "Golden Hour" needed for occupants to exit safely and for BOMBA personnel to navigate the building during rescue and firefighting operations.
| Feature | Standard HVAC Ducting | EKG Pressurization Ducts |
| Primary Goal | Occupant Comfort | Life Safety & Smoke Blocking |
| Required Pressure | Low (Commercial) | High (Differential of 50 Pa) |
| Fire Rating | None | Mandatory (FRL 120/120/120) |
| System Trigger | Thermostat | Automatic (Fire Alarm Trigger) |
| BOMBA Approval | Not Required | Mandatory for High-Rise FC |
Total 3D BIM Coordination: High-rise ceiling voids are extremely congested. We utilize 3D modeling to route fire-rated ducts through crowded spaces, ensuring zero "clashes" with sprinklers, cable trays, or structural beams.
Turnkey BOMBA Submission: We assist in the preparation of technical drawings and perform mandatory Pressure Differential Tests and Airflow Balancing required for Fire Certificate (FC) applications and annual renewals.
Strategic Regional Support: Based in Kuala Lumpur, we provide professional pressurization services for Grade-A office towers, luxury condominiums, and hospitals across the region.
