In the high-rise landscape of Kuala Lumpur and Selangor, the escape stairwell is the most critical survival zone during a fire. Staircase Pressurization Ducts are engineered to inject fresh air into these stairwells, creating a high-pressure shield that physically prevents toxic smoke from entering the escape route. EKG M&E Sdn Bhd specializes in the installation of these life-safety systems, ensuring they remain operational under extreme conditions to meet BOMBA and Uniform Building By-Laws (UBBL) requirements.
The primary goal of a pressurization 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, the ductwork must deliver a precise volume of air without leakage.
Fire-Rated Protection: Since these ducts often travel through multiple floors or "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 a lower floor, the duct remains intact to deliver fresh air to the floors above.
High-Pressure Construction: Unlike standard HVAC, these ducts are built to withstand higher internal pressures to ensure the 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 is triggered.
Barometric Relief Dampers: To prevent the stairwell from becoming over-pressurized (which would make it 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 run fan motors 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 operations.
| Feature | Standard HVAC Ducting | EKG Pressurization Ducts |
| Primary Goal | Comfort Cooling | 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 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.
