Duct sealing verification

Duct Sealing Verification by EKG M&E Sdn Bhd

In the 2026 Malaysian engineering landscape, Duct Sealing Verification is the definitive process used to prove that an air distribution system is airtight and compliant. Under the Energy Efficiency and Conservation Act (EECA) 2024 and the DOSH ICOP IAQ 2026, "assumed" airtightness is no longer sufficient. Building owners in Kuala Lumpur and Selangor must now provide empirical data to verify that their duct seals are performing to design specifications.

At EKG M&E Sdn Bhd, we apply 34 years of mechanical depth to verify your duct seals, ensuring your facility achieves a 5-Star Energy Intensity Label and meets the legal bacterial ceiling.

1. The Engineering Logic of Verification

Verification is the "Audit" phase of duct sealing. Even if a system has been sealed with mastic or aerosol, environmental factors—such as thermal expansion and building vibration—can compromise those seals over time.

• Quantifying the "Leakage Gap": Verification testing measures the actual air loss in $l/s/m^2$. This data proves that the sealing work has reduced the system's "Static Pressure" load, allowing your Variable Frequency Drives (VFDs) to operate at their most efficient frequency ($Hz$).

• ATC 6 Verification: For Grade-A offices, we verify that the system meets Airtightness Class 6 (ATC 6). This means leakage is verified to be below 1%, a critical requirement for maintaining a low Building Energy Index (BEI).

• Hermetic Integrity (DOSH 2026): Verification ensures your ducts aren't "aspirating" dirty air from ceiling voids, keeping your air path sterile and compliant with the mandatory 500 cfu/m³ bacterial limit.

2. Our 2026 Verification Protocol

We utilize medical-grade, multi-stage testing to provide the "Digital Audit Trail" required for your annual regulatory submissions:

• DW/143 Standard Pressure Testing: We isolate the sealed section and pressurize it to its design operating pressure. We then use calibrated flow meters to record the precise leakage rate, comparing it against the allowable limits for Class A, B, or C.

• Robotic "Seal Audit" Inspections: We deploy high-definition camera robots to visually inspect internal seams. This is especially critical for verifying Aerosol Internal Sealing, ensuring the "adhesive bridges" are structurally sound across every joint.

• Ultrasonic Forensic Checks: In risers and shafts where visual access is impossible, we use ultrasonic detectors to "listen" for high-frequency sounds generated by air escaping through failed seals.

• Smoke Barrier Validation: Using Non-Toxic Smoke Generators, we verify that the seals act as a complete barrier to air movement. This is a primary requirement for the annual renewal of your BOMBA Fire Certificate (FC).

3. Compliance & Audit Documentation (EECA 2024)

At EKG M&E Sdn Bhd, our verification reports are designed to satisfy multiple 2026 regulatory audits:

Why Choose EKG M&E Sdn Bhd?

• 34 Years of Engineering Depth: Based in KL, we understand the mechanical physics of high-rise plants. We ensure that verification pressures never damage your Smart Actuators or internal insulation.

• Turnkey Reporting: We provide a comprehensive digital audit package containing robotic footage, calibrated test logs, and engineering certificates recognized by the Energy Commission (Suruhanjaya Tenaga).

• Total 3D BIM Coordination: For new builds, we identify "Verification Zones" in 3D to ensure testing is fast, accurate, and non-disruptive to other trades.
