Fire Ducting Systems

Fire Ducting Systems by EKG M&E Sdn Bhd

In the high-rise landscape of KL and PJ, standard ventilation ducts can become a "highway" for fire and toxic gases to spread between floors. EKG M&E Sdn Bhd specializes in Fire Ducting Systems, engineering robust, heat-resistant distribution networks designed to maintain structural integrity during an emergency. Whether it is for smoke extraction or protecting a pressurized escape route, our systems meet the strict BS 476-24 and BOMBA standards.

Engineering the Fire-Rated Air Path

A Fire Ducting System differs from standard HVAC ducting in its ability to withstand extreme temperatures without collapsing or allowing "fire-bypass." We focus on three critical engineering criteria:

• Integrity (E): The ability of the duct to remain intact and prevent the passage of flames and hot gases through the duct wall.

• Insulation (I): The ability of the duct to limit the temperature rise on the "cool" side, preventing the ignition of nearby combustible materials in unaffected rooms.

• Stability (S): The ability of the duct and its support hangers to remain in place under fire conditions (typically 250 degrees Celsius for 2 hours) without collapsing.

Our Specialized Ducting Solutions

• Smoke Spill Exhaust Ductwork:

  These ducts are designed to carry hot smoke (250 degrees Celsius) from the fire zone to the rooftop extraction fans. We utilize heavy-gauge galvanized steel (GI) reinforced with fire-rated coatings or specialized pre-insulated panels.

• Pressurization Ductwork:

  To keep stairwells smoke-free, these ducts must remain operational even if the fire is right outside the duct wall. We ensure these "Life-Safety" ducts are fully fire-rated to prevent smoke from being sucked into the clean air stream.

• Kitchen Exhaust Fire Ducting:

  Kitchen grease is highly flammable. We install specialized fire-rated ducting (often Stainless Steel 304/316) for commercial kitchens in malls and hotels, ensuring a "Grease Fire" stays contained within the duct until the suppression system activates.

• Intumescent Fire and Smoke Dampers:

  At every point where a duct penetrates a fire-rated wall or floor slab, we install motorized dampers. These are interlocked with the Main Fire Alarm Panel (MFAP) to snap shut instantly, sealing off the fire compartment.

Materials and Compliance Standards

Why Choose EKG M&E Sdn Bhd?

• HVAC & Clean Air Specialist: We don't just "install a box." We analyze the Static Pressure of the fire-rated ducting. Because fire-rated coatings or wraps add weight and internal friction, we ensure your fans (VFD-controlled) have the necessary torque to maintain the mandatory 10 Air Changes Per Hour (ACH).

• BOMBA Certification Support: We provide the necessary Material Safety Data Sheets (MSDS) and Installation Certificates (Form G/F) required for your building's annual Fire Certificate (FC) audit.

• Klang Valley Strategic Support: Based in Kuala Lumpur, we provide professional auditing and maintenance for fire-rated ducting systems across major commercial and industrial hubs in the Klang Valley.
