Kitchen grease fire rated ducting

Kitchen Grease Fire Rated Ducting by EKG M&E Sdn Bhd

In the high-traffic culinary landscape of Kuala Lumpur and Selangor, kitchen grease is one of the most dangerous fuels for building fires. Kitchen Grease Fire Rated Ducting is a specialized, liquid-tight extraction system designed to contain "flash fires" that occur when accumulated grease ignites. EKG M&E Sdn Bhd provides industrial-grade installations that strictly comply with NFPA 96, BOMBA standards, and the Uniform Building By-Laws (UBBL).

The Engineering of Grease Fire Containment

Standard galvanized ductwork is entirely unsuitable for grease extraction. Grease is highly flammable and acidic; it requires a system that is both leak-proof and fire-resistant.

1. Liquid-Tight Welded Construction

To prevent flammable oils from leaking into ceiling voids, our kitchen grease ducts are built using 1.2mm to 1.6mm heavy-gauge carbon steel or stainless steel.

• Continuous Welding: Unlike standard ducts that use rivets or gaskets, grease ducts must be continuously TIG or MIG welded at all seams and joints. This ensures the system is liquid-tight and flame-tight.

• Integrity (FRL 120/120/120): The assembly is certified to maintain its integrity for 2 hours. This containment prevents a fire inside the duct from spreading to the rest of the building's structure.

2. Advanced Fire-Wrap Insulation

Because grease fires can burn at temperatures exceeding 1000°C, the duct itself becomes a radiant heater.

• Thermal Barrier: We apply certified high-density mineral wool or ceramic fiber fire-wraps. This ensures that even if the duct is on fire internally, the exterior surface remains cool enough to prevent nearby materials (like electrical cables or wood) from igniting.

• Zero-Clearance Certification: Our wraps allow for tighter installations in crowded KL mall ceilings or shop-lots where space is at a premium.

Critical Operational & Energy Benefits

As a BOMBA-Compliant M&E Specialist, EKG ensures your kitchen safety infrastructure supports long-term profitability:

• TNB Energy Efficiency (Airflow Optimization):

  A fully welded, airtight grease duct eliminates static pressure loss. This high level of seal integrity allows your Variable Frequency Drive (VFD) to maintain optimal smoke and heat extraction at lower motor frequencies (Hz). This directly results in a lower monthly TNB electricity bill for your F&B operation.

• EECA 2024 & Odor Management:

  Under the Energy Efficiency and Conservation Act (EECA) 2024, efficient mechanical transport is mandatory. Our liquid-tight seals ensure that heavy cooking odors and heat are transported directly to the discharge point without escaping into public or office areas, protecting your Building Energy Index (BEI).

• Reduced Insurance Risk:

  Installing a certified grease fire-rated system significantly lowers your risk profile. Many Malaysian insurance providers require proof of NFPA 96 compliance to maintain coverage for commercial kitchens.
