In the vertical architecture of Kuala Lumpur and Selangor, the installation of a staircase pressurization system is a high-precision life-safety task. It is not merely about mounting a fan; it is about creating a hermetically managed air environment that keeps escape routes clear of smoke.
EKG M&E Sdn Bhd provides turnkey installation services that ensure your system meets MS 1472 (Code of Practice for Smoke Control using Pressurization) and BOMBA requirements for high-rise safety.
A successful staircase pressurization project requires a synchronized approach across structural, mechanical, and electrical engineering.
The airway must be able to withstand both high internal pressure and external fire exposure.
Fire-Rated Enclosure: We install ducts rated for 2 hours (FRL 120/120/120). This involves encasing the galvanized steel duct in certified fire-rated boards or high-density mineral wool wraps.
Pressure Testing: Before the shaft is sealed, we perform Duct Leakage Testing (DW/143). Any leaks in the shaft will prevent the system from reaching the mandatory 50 Pa pressure target.
Precision Placement: Fans are typically installed at the roof level (top-down) or ground level (bottom-up). We utilize reinforced plinths with anti-vibration mountings to prevent structural noise from entering the stairwell.
Flexible Connections: We utilize certified fire-rated flexible connectors between the fan and the ducting to accommodate thermal expansion during a fire event.
Strategic Discharge: We install supply grilles at every landing or every alternate floor, depending on the building height.
Balancing Dampers: Each outlet is fitted with an adjustable volume control damper to ensure the air pressure is uniform from the bottom floor to the top floor.
Fire Alarm Trigger: The system is hardwired into the Fire Alarm Monitoring System (FAMS). Upon a smoke signal, the fans must ramp up to full speed within seconds.
VFD Optimization: We install Variable Frequency Drives (VFDs) that adjust air volume based on whether the stairwell doors are open or closed, maintaining the balance between smoke rejection and door-opening force.
As a BOMBA-Compliant M&E Specialist, EKG ensures your installation supports long-term building performance:
TNB Energy Efficiency (Airtight Precision): A system with high air leakage forces the fan to run at higher speeds, consuming more power. By ensuring a Class C Airtight installation, we allow the fan to hit its target at lower frequencies (Hz), directly resulting in a lower monthly TNB electricity bill during mandatory testing.
EECA 2024 & Building Compliance: Under the Energy Efficiency and Conservation Act (EECA) 2024, every building service must be energy-optimized. Our precision-sealed fire ducts prevent the waste of conditioned air, helping lower your Building Energy Index (BEI).
Prevention of "Door-Lock": If the system is installed without proper relief venting, the pressure can become too high, making it impossible for children or the elderly to open the fire doors. We calibrate the system to ensure the door opening force never exceeds 110 N.
Total 3D BIM Coordination: We utilize 3D modeling to route fire-rated ducts through crowded KL high-rise shafts, ensuring zero "clashes" with sprinklers, standpipes, or structural beams.
Turnkey BOMBA Submission: We perform the mandatory Pressure Differential Test, Door Opening Force Test, and Anemometer Airflow Traverse required for your Fire Certificate (FC) application.
Strategic Regional Support: Based in Kuala Lumpur, we provide professional installation and audit services for Grade-A office towers, luxury condominiums, and hospitals across Malaysia.
