Kitchen hood SS ductwork

Kitchen Hood SS Ductwork by EKG M&E Sdn Bhd

In the professional culinary environments of Kuala Lumpur and Selangor, the connection between the kitchen hood and the main exhaust fan is the most high-risk zone for fire and hygiene failures. Kitchen Hood Stainless Steel (SS) Ductwork is engineered to bridge this gap with a liquid-tight, fire-resistant conduit. EKG M&E Sdn Bhd specializes in the precision fabrication of SS ducting that seamlessly integrates with your kitchen hoods, ensuring that 100% of grease-laden vapors are captured and safely transported out of the building.

The Engineering of Hood-to-Fan Connectivity

The ductwork immediately following a kitchen hood handles the highest concentration of heat and liquified grease. If this section is not liquid-tight, grease will leak onto the hood exterior or into the ceiling void, creating a significant fire hazard.

1. Material Integrity: Grade 304/316 Stainless Steel

We utilize high-grade stainless steel to ensure the ducting survives the aggressive environment of a commercial kitchen.

• Corrosion Immunity: Constant exposure to steam and high-strength degreasers will rapidly rust galvanized iron. Stainless steel remains inert and structurally sound, ensuring no "pinhole" leaks develop over time.

• Non-Porous Surface: SS does not allow grease to bond deeply with the metal, making it significantly easier to maintain the "clean-room" standards required in modern F&B operations in the Klang Valley.

2. Liquid-Tight TIG Welded Seams

To comply with NFPA 96 and BOMBA standards, the ductwork connected to a kitchen hood must be liquid-tight.

• Continuous Welds: We utilize TIG (Tungsten Inert Gas) welding for all longitudinal and circumferential seams. This transforms the duct into a solid, hermetically sealed pipe that prevents liquified grease from escaping into the building structure.

• Smooth Transitions: We custom-fabricate SS plenum boxes and transitions to connect the hood to the ducting. These are designed with smooth internal radii to minimize air turbulence and prevent grease "dropout."

Critical Operational & Safety Benefits

As an HVAC and Fire Safety Specialist, EKG ensures your hood ducting protects your facility's operational license:

• TNB Energy Efficiency (The Scrubber Synergy):

  Properly engineered hood ducting minimizes static pressure. By ensuring the air path is Airtight (Class C) and aerodynamically smooth, we allow your Variable Frequency Drive (VFD) to run exhaust fans at lower frequencies (Hz). Reducing the load on high-static kitchen fans results in a significantly lower monthly TNB electricity bill.

• BOMBA & Fire Safety Compliance:

  Malaysian Uniform Building By-Laws (UBBL) mandate that kitchen exhaust systems be fire-rated. Our SS ductwork maintains its structural integrity at high temperatures, providing a critical containment barrier during a potential duct fire.

• EECA 2024 & IAQ Control:

  Under the Energy Efficiency and Conservation Act (EECA) 2024, efficient mechanical transport is a priority. Our hood ducting ensures that toxic smoke and rancid odors 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?

• Maintenance Accessibility: We install liquid-tight, BOMBA-compliant access doors at the hood connection and at specific intervals to allow for mandatory professional degreasing.

• Total Performance Commissioning: Post-installation, we perform Anemometer Audits to certify that the face velocity at the hood is sufficient to capture all cooking byproducts before they escape into the kitchen.

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