Smoke Control Systems by EKG M&E Sdn Bhd
In the high-density urban landscape of KL and Selangor, smoke control is the most critical life-safety element of a building’s M&E infrastructure. While standard HVAC provides comfort, a Smoke Control System is engineered to manage toxic gases and extreme heat during a fire. EKG M&E Sdn Bhd specializes in integrated smoke management solutions that meet the strict BOMBA (Fire and Rescue Department of Malaysia) and Uniform Building By-Laws (UBBL) requirements.
The Three Pillars of Smoke Management
Effective smoke control requires a "Total System" approach where fans, dampers, and architectural reservoirs work in perfect synchronization.
1. Smoke Extraction (Mechanical & Natural)
The goal is to remove smoke as fast as it is produced to maintain a "Clear Layer" for evacuation.
-
Mechanical Smoke Spill (10 ACH): We install high-capacity axial fans rated for 250°C for 2 hours. These fans "flush" the fire zone at a rate of 10 Air Changes Per Hour (ACH).
-
Atrium Smoke Exhaust: For large open volumes like hotel lobbies or malls, we calculate the smoke plume buoyancy to ensure the layer stays at least 2.5 meters above the highest occupied floor.
-
Natural Smoke Vents (NSHEV): Roof-mounted hatches that open via heat-sensitive fusible links or fire signals, allowing hot gases to escape naturally.
2. Pressurization (Life Safety Zones)
To keep escape routes 100% smoke-free, we utilize Positive Pressure.
-
Stairwell Pressurization: We pump fresh outdoor air into stairwells to maintain a pressure of 50 Pa. This ensures that when a fire door opens, air blows out, preventing smoke from entering the exit path.
-
Lift Lobby Pressurization: Maintaining a slightly lower pressure (approx. 15 Pa) to create a "pressure shield" between the fire zone and the stairwell.
3. Smoke Containment & Compartmentation
To prevent the HVAC ductwork from acting as a "highway" for smoke, we install specialized barriers:
-
Motorized Smoke Dampers: Installed at fire-rated wall penetrations, these are interlocked with the Main Fire Alarm Panel (MFAP) to snap shut instantly.
-
Smoke Curtains: Automated fabric barriers that drop from the ceiling to create a "Smoke Reservoir," trapping gases in a specific zone for extraction.

Why Choose EKG M&E Sdn Bhd?
-
HVAC & Clean Air Specialist: We ensure your "Smoke Mode" logic is flawless. When the smoke spill fans turn on, the general office AC must shut down to prevent the mechanical mixing of smoke into unaffected rooms.
-
Testing and Commissioning (T&C): We don't just "install and leave." We provide professional Hot Smoke Visualization Testing and Differential Pressure Audits to prove your building is 100% safe before your annual Fire Certificate (FC) renewal.
-
Klang Valley Strategic Support: Based in Kuala Lumpur, we provide priority 24/7 maintenance and emergency response for smoke control systems across the Klang Valley's premier commercial and industrial sites.
