In the dense urban landscape of Kuala Lumpur and Selangor, managing hazardous or high-temperature air requires more than just standard ventilation. Fire-Rated Exhaust Ducts are specialized systems engineered to maintain structural integrity and contain toxic gases during a fire emergency. EKG M&E Sdn Bhd provides high-performance, fire-rated installations that strictly adhere to BOMBA standards and the Uniform Building By-Laws (UBBL), ensuring that your extraction paths do not become a liability during a thermal event.
Standard exhaust ducts are typically made of thin-gauge galvanized steel that will buckle and fail at temperatures as low as $200°C$. Fire-rated exhaust systems must remain operational for at least 2 hours at temperatures exceeding $250°C$.
We install exhaust systems certified for a 120-minute duration across three critical performance criteria:
Stability: The duct and its reinforced, fire-rated hanger system must not collapse, ensuring the extraction path remains open for smoke spill or heat removal.
Integrity: The system must be smoke-tight and flame-tight to prevent the spread of fire from the exhaust stream into other building compartments.
Insulation: The duct must prevent radiant heat from transferring to the "cold side," ensuring combustible materials (like data cables or structural insulation) outside the fire zone do not ignite.
Pre-Fabricated Fire Ducts: Utilizing heavy-gauge steel with factory-applied fire-resistive coatings that are moisture-resistant—a necessity for the humid Malaysian climate.
Fire Wrap Insulation: For retrofits or complex routes, we apply certified Rockwool or Ceramic Fiber blankets secured with stainless steel mesh and foil to achieve a certified 2-hour fire rating.
Intumescent Fire Stopping: Where the exhaust duct penetrates a fire-rated wall or floor, we install specialized seals that expand under heat to maintain the building's compartmentation.
As a BOMBA-Compliant M&E Specialist, EKG ensures your safety infrastructure contributes to operational efficiency:
TNB Energy Efficiency (The Airtight Advantage):
Fire-rated exhaust ducts are held to much higher airtightness standards to prevent smoke leakage. This superior seal integrity minimizes static pressure loss during daily use. By eliminating air waste, your Variable Frequency Drive (VFD) can maintain required airflows at lower frequencies (Hz), resulting in a lower monthly TNB electricity bill.
Safe Evacuation & Tenability:
By effectively extracting smoke from basements, corridors, or kitchens, our installations keep escape routes clear. This provides the "Golden Hour" needed for safe occupant egress and for BOMBA personnel to initiate rescue operations.
EECA 2024 & Regulatory Compliance:
Under the Energy Efficiency and Conservation Act (EECA) 2024, efficient building services are mandatory. Our precision-sealed systems prevent the leakage of conditioned air, helping lower your Building Energy Index (BEI).

| Joint Sealing | Standard Mastic | Certified Intumescent Sealant |
| Hanger Systems | Standard C-Channel | Reinforced Fire-Rated Supports |
| Primary Goal | Air Removal | Life Safety & Fire Containment |
Total 3D BIM Coordination: We utilize 3D modeling to coordinate the fire exhaust route with sprinklers, cable trays, and structural beams, ensuring a "clash-free" installation that maintains required fire separation.
Turnkey BOMBA Submission: We assist in the preparation of technical drawings and documentation required for Fire Certificate (FC) applications and annual renewals.
Total Performance Commissioning: Post-installation, we perform professional Smoke Tests, Duct Leakage Tests (DW/143), and Airflow Balancing to verify that the system activates and performs as designed during a fire signal.
