In the deep subterranean levels of Kuala Lumpur and Selangor, basement exhaust ductwork is the most critical mechanical component for both daily air quality and life safety. Because vehicle exhaust contains toxic Carbon Monoxide (CO) and fires in enclosed spaces generate extreme heat, these ducts must be engineered to survive as "life-support lines" for the building.
EKG M&E Sdn Bhd specializes in the design and installation of fire-rated networks that ensure your facility adheres to MS 1780, BOMBA standards, and the Uniform Building By-Laws (UBBL).
Under BOMBA regulations, basement exhaust ducts must maintain a 2-hour fire resistance rating. This is measured by three distinct criteria:
Integrity: The duct must not collapse or breach when transporting superheated gases (up to 400°C), ensuring smoke is contained within the system.
Insulation: The external surface of the duct must remain cool enough to prevent "auto-ignition" of combustible materials (like data cables or storage) in adjacent rooms.
Stability: The support system (hangers and brackets) must be reinforced to prevent the ductwork from buckling under intense thermal expansion.
EKG Solution: We utilize 1.2mm heavy-gauge galvanized steel (G.I.) encased in BOMBA-approved fire-rated boards or high-density fire wraps to meet these stringent 2-hour requirements.
Our fire-rated ductwork is engineered to transition instantly between two operational states:
Normal Mode (CO Extraction): The system works with CO sensors and Variable Frequency Drives (VFDs) to remove vehicle fumes.
Fire Mode (Smoke Spill): When triggered by the Fire Alarm Monitoring System (FAMS), the energy-saving logic is bypassed, and the system extracts high-volume, toxic smoke to keep escape routes clear.
As a specialized M&E contractor, EKG ensures your fire-rated infrastructure supports building efficiency:
TNB Energy Efficiency (Class C Airtightness):
Leaky ducts force fans to work harder. By ensuring a Class C Airtight installation with certified intumescent sealants, we eliminate static pressure loss. This allows your fans to hit safety targets at lower frequencies (Hz) during mandatory weekly testing, directly reducing your monthly TNB electricity bill.
EECA 2024 & Building Compliance:
Under the Energy Efficiency and Conservation Act (EECA) 2024, mechanical air transport must be optimized for minimal waste. Our precision-engineered systems prevent energy "bleeding" and ensure your Building Energy Index (BEI) remains within green compliance levels.
Space Optimization:
KL basements often have low ceiling clearances. We utilize 3D BIM Coordination to route flat-oval or rectangular duct profiles that maximize vehicle clearance while maintaining the required cross-sectional area for smoke extraction.
| Feature | Standard HVAC Ducting | EKG Fire-Rated Exhaust Ducting |
| Material Gauge | 0.5mm – 0.8mm GI | 1.2mm (BOMBA Standard) |
| Operating Temp | Ambient (Max 40°C) | High-Temp (300°C - 400°C) |
| Fire Resistance | None | Mandatory 2-Hour (FRL 120/120/120) |
| Airtightness | Class A / B | Class C / D (Airtight Precision) |
| BOMBA Required | No | Mandatory for High-Rise/Basement FC |
Total 3D BIM Coordination: We model the exhaust network in 3D to ensure zero "clashes" with sprinklers, plumbing, and electrical trays, preserving maximum vehicle headroom.
Turnkey BOMBA Submission: We perform the mandatory Smoke Tests and Anemometer Airflow Traverse required for your annual Fire Certificate (FC) renewal.
Strategic Regional Support: Based in Kuala Lumpur, we provide professional safety audits and technical proposals for shopping malls, Grade-A office towers, and luxury residential basements.
