In the dense urban landscape of KL and PJ, a Mechanical Smoke Venting System (MSVS) is a non-negotiable life-safety requirement for deep basements, windowless rooms, and large open-plan commercial spaces. Unlike natural venting which relies on buoyancy, mechanical venting uses high-powered fans to actively "pull" smoke out of a building. EKG M & E Sdn Bhd specializes in the design, installation, and BOMBA certification of these critical extraction networks.
High-Temperature Axial Smoke Spill Fans These are the powerhouse of the system, certified to operate for 2 hours at 250°C or higher. They are designed to withstand the extreme thermal stress of a fully developed fire while maintaining the mandatory 10 Air Changes per Hour (ACH).
Fire-Rated Extraction Ductwork Smoke is transported through galvanized steel ducts encased in fire-rated boarding or ceramic wraps. This ensures the duct maintains its structural integrity (Stability) and prevents smoke from leaking into other fire compartments (Integrity).
Motorized Smoke & Fire Dampers Strategically placed where ducts penetrate walls or floors, these dampers are interlocked with the Fire Alarm Monitoring System (FAMS). They snap open in the fire zone to maximize extraction and close in non-affected areas to prevent smoke migration.
Make-Up Air (Replacement Air) Systems Mechanical venting creates a vacuum. To prevent high-pressure zones that could "lock" fire doors shut, we install supply fans or motorized louvers that introduce fresh air at a slightly lower rate than the exhaust, maintaining a balanced flow.
Fire Priority Control Logic Our custom control panels feature a "Fire Override" mode. Upon activation, the system bypasses all energy-saving VFD setpoints and thermal overloads, forcing the fans to run at 100% capacity until the emergency is cleared.
Visibility for Evacuation: By rapidly removing the "smoke plug," the system maintains a clear air layer (typically 2.5 meters above the floor), allowing occupants to see exit signs and move safely toward escape stairs.
Structural Protection: Venting removes a significant portion of the fire's heat, preventing the building's concrete or steel structure from reaching critical failure temperatures.
Tactical Access for BOMBA: A clear, vented environment allows firefighters to locate the seat of the fire quickly and perform search-and-rescue operations with improved visibility and reduced heat stress.
Space Efficiency: In high-rise developments in Kuala Lumpur, mechanical venting allows for larger floor plates and deeper basements where natural ventilation is physically impossible.
BOMBA & UBBL Compliance: We ensure every design meets the Malaysian Uniform Building By-Laws, providing the "Cold Smoke" testing and airflow velocity reports required for your annual Fire Certificate (FC) renewal.
Engineering-Led Integration: As an M&E specialist, we manage the entire lifecycle—from CFD Airflow Analysis and electrical cabling to the final commissioning of the fans and dampers.
Strategic Support in KL & PJ: We provide 24/7 technical support and rapid maintenance for smoke spill systems in major shopping malls, office towers, and high-end condominiums across the Klang Valley.
