Kitchen grease-rated SS ductwork

Kitchen Grease-Rated SS Ductwork by EKG M&E Sdn Bhd

In the high-volume F&B landscape of Kuala Lumpur and Selangor, kitchen grease is the leading cause of catastrophic building fires and persistent hygiene failures. Kitchen Grease-Rated Stainless Steel (SS) Ductwork is engineered specifically to contain flammable oils and high-temperature cooking vapors. EKG M&E Sdn Bhd specializes in the design, fabrication, and installation of liquid-tight SS systems that exceed BOMBA and NFPA 96 requirements, ensuring your commercial kitchen remains safe, clean, and compliant.

The Engineering of Liquid-Tight Containment

Standard galvanized ducting is unsuitable for grease extraction because its mechanical joints (S-cleats and drive slips) allow liquified grease to seep into ceiling voids. Our grease-rated SS systems eliminate this risk at the engineering level.

1. Material Purity: Grade 304/316 Stainless Steel

We utilize heavy-gauge stainless steel to withstand the aggressive nature of kitchen exhaust.

• Corrosion Immunity: Commercial degreasers and high-moisture cooking vapors rapidly corrode galvanized iron. Stainless steel is immune to this degradation, ensuring the duct walls do not thin or develop "pinhole" leaks over time.

• Non-Absorbent Surface: Unlike porous materials, SS does not allow grease to "soak" into the substrate, making it significantly easier to perform mandatory professional cleaning and degreasing.

2. Full-Penetration TIG Welding

The "Grease-Rated" designation requires the duct to be liquid-tight.

• Monolithic Construction: We utilize TIG (Tungsten Inert Gas) welding for every longitudinal and circumferential seam. This transforms the ductwork into a continuous metal pipe with zero mechanical openings for grease to escape.

• Fire Integrity: A fully welded SS duct provides a superior barrier during a "flash fire" or duct fire, maintaining its structural shape far longer than bolted or cleated systems.

Critical Operational & Safety Benefits

As an HVAC and Fire Safety Specialist, EKG ensures your grease-rated system protects your facility's bottom line:

• TNB Energy Efficiency (Clean Duct Synergy):

  Grease buildup increases internal surface roughness, which creates turbulence and forces exhaust fans to work harder. By utilizing an airtight, easy-to-clean SS network, we maintain optimal airflow. This allows your Variable Frequency Drive (VFD) to run fan motors at lower frequencies (Hz). Reducing the load on high-static kitchen fans leads to a significantly lower monthly TNB electricity bill.

• BOMBA & NFPA 96 Compliance:

  Malaysian Uniform Building By-Laws (UBBL) mandate strict fire-rated standards for kitchen exhaust. Our systems feature BOMBA-compliant, grease-tight access panels at every change of direction and every $3\ m$, allowing for thorough inspection and clearing of fire hazards.

• EECA 2024 & IAQ Excellence:

  Under the Energy Efficiency and Conservation Act (EECA) 2024, maintaining efficient mechanical transport is vital. Our grease-rated ducts ensure that rancid odors and toxic smoke are removed effectively, protecting the Indoor Air Quality (IAQ) of your dining area and preventing cross-contamination.

Performance and Safety Matrix

Why Choose EKG M&E Sdn Bhd?

• Internal Slope Design: We engineer our grease duct runs with a mandatory slope towards the hood or a dedicated grease reservoir, preventing the pooling of oils that act as fuel for fires.

• Total Performance Commissioning: Post-installation, we perform professional Light Tests or Smoke Tests to certify that the ductwork is 100% liquid-tight before commissioning.

• Strategic Selangor Support: Based in Kuala Lumpur, we provide turnkey grease-rated SS services for shopping mall F&B clusters, hotel central kitchens, and food processing plants across the region.
