BOMBA-Compliant Fire-Rated Scrubber Ducts

BOMBA-Compliant Fire-Rated Scrubber Ducts by EKG M&E Sdn Bhd

In 2026, BOMBA-Compliant Fire-Rated Scrubber Ducts are a mandatory safety requirement for commercial kitchens and industrial facilities where exhaust paths penetrate fire-rated compartments. Under the Uniform Building By-Laws (UBBL) and the latest BOMBA enforcement, ductwork carrying grease and odor particulates is considered a high-risk fuel source. For high-rise developments in Kuala Lumpur and Selangor, these ducts must be engineered to contain an internal grease fire and prevent external fire spread for a duration of 2 to 4 hours, ensuring your building maintains a 5-Star BEI.

At EKG M&E Sdn Bhd, we apply 34 years of mechanical engineering expertise to provide certified fire-rated duct solutions. We ensure your scrubber system is a fail-safe barrier, compliant with MS 1472, and optimized for your 5-Star Energy Intensity Label.

1. The Engineering Logic: Fire Containment (Internal & External)

A scrubber duct must be rated for "Stability," "Integrity," and "Insulation" to satisfy Malaysian fire safety codes.

• Containing the "Grease Fire": If a fire ignites within the kitchen hood and enters the duct, the fire-rating ensures the flames do not melt the ductwork or ignite adjacent ceiling materials. This protects the structural integrity of your mechanical floor.

• Preventing "Thermal Radiation": In a fire, the exterior of a standard duct can reach temperatures that ignite nearby electrical cables or furniture via radiation. Our fire-rated systems utilize Insulated Fire Wraps or Pre-fabricated Intumescent Coatings that keep the external surface temperature safe.

• Lowering the BEI: Traditional thick-walled fire ducts can be heavy and create air turbulence. We utilize Aero-Dynamic Fire-Rated Systems that maintain a smooth internal bore. By reducing skin friction, we allow your Variable Frequency Drives (VFDs) to operate at peak efficiency, directly improving your Building Energy Index (BEI).

2. Specialized BOMBA-Ready Integration Protocols

We follow a rigorous mechanical standard to ensure your exhaust system meets SIRIM and BOMBA benchmarks:

A. Certified Fire-Wrap Systems

We specify high-temperature silicate or ceramic fiber wraps that are SIRIM-certified. These wraps are applied to the external surface of the stainless steel or GI scrubber duct, providing a flexible and lightweight fire barrier that allows the duct to expand and contract without compromising the fire-rating.

B. Fire-Rated Expansion Joints and Hangers

Standard hangers can fail under the extreme heat of a kitchen fire, causing the duct to collapse. We engineer Fire-Resistant Support Systems and expansion joints that maintain the duct's position and integrity during a thermal event, ensuring the smoke control strategy continues to function.

C. Intumescent Fire-Stopping at Penetrations

Where the scrubber duct passes through a fire-rated wall or floor slab, we install BOMBA-approved intumescent seals. These seals expand when exposed to heat, closing the gap between the duct and the structure to prevent smoke and flame "bypass."

4. Why Certified Fire-Rating is Essential for 2026

• Securing the Annual Fire Certificate (FC): BOMBA officials in KL and Selangor prioritize kitchen exhaust paths during inspections. Our fire-rated systems provide the technical proof and labeling required for a smooth FC renewal.

• Lowering TNB Maximum Demand: By utilizing high-performance, low-leakage fire-rated ducting, we ensure your Kitchen Exhaust Fan (KEF) is not fighting air leaks. This flattens your energy profile and secures your 5-star efficiency rating.

• Bio-Security & IAQ (DOSH 2026): Our fire-rated systems are non-porous and resistant to tropical mold. This maintains a sterile air path from the scrubber to the discharge point, ensuring the highest indoor air quality and food safety standards.
