Duct Leakage Testing

In the 2026 Malaysian regulatory landscape, Duct Leakage Testing (DLT) is no longer an optional commissioning step—it is a mandatory engineering audit. Driven by the Energy Efficiency and Conservation Act (EECA) 2024 and the DOSH ICOP IAQ 2026, maintaining a hermetic air distribution network is now the primary requirement for securing a building's 5-Star Energy Intensity Label.

At EKG M&E Sdn Bhd, we apply 34 years of mechanical engineering expertise to treat your ductwork as a high-performance asset, ensuring your "Injection Path" remains airtight and audit-ready.

1. The 2026 Compliance Mandate: ATC 6 & DW143

Under the EECA 2024, air leakage is classified as a "Regulatory Liability." New and retrofitted commercial buildings in Kuala Lumpur and Selangor are now pushed toward Airtightness Class 6 (ATC 6).

• DW143 Standard: This is the international benchmark for the "Practical Guide to Ductwork Leakage Testing." We utilize it to certify that your system meets its designated class (A, B, or C).

• The 1% Goal: For premium facilities and hospitals, we target a leakage rate of less than 1%. This prevents "Plenum Infiltration," where dirty air from ceiling voids is sucked into the clean air stream.

• The Fan Cube Law: This is a critical engineering fact—fixing a 15% leak doesn’t just save 15% energy. It allows your Variable Frequency Drives (VFDs) to drop fan speeds significantly, often reducing fan power consumption by over 30%.

2. Forensic Testing & Verification Methods

We utilize a multi-stage verification process to ensure 100% volumetric integrity:

• PANDA Pressure Testing: Using high-precision Positive and Negative Duct Accreditation (PANDA) testers, we pressurize isolated duct sections to their design operating pressure and measure the exact air loss ($l/s/m^2$).

• Non-Toxic Smoke Testing: To pinpoint invisible gaps in vertical risers or joints, we deploy non-toxic smoke generators. The escaping smoke visually identifies every failure point for immediate rectification.

• Ultrasonic Detection: For high-pressure systems where visual access is limited, we use ultrasonic "pingers" to listen for the specific frequency of air escaping through microscopic gaps.

• Robotic 3D Mapping: We deploy high-definition camera robots to map the internal state of the ductwork, providing verifiable "Before & After" evidence for your Registered Energy Manager (REM).

4. Strategic Benefits for Your Asset

• TNB Bill Reduction: Directly lowers monthly "Maximum Demand" charges by reducing the peak load on AHU motors.

• DOSH 2026 Readiness: Ensures you stay below the mandatory 500 cfu/m³ bacterial ceiling by preventing unfiltered air from entering the system.

• Condensation Prevention: Eliminates the "Cold Air Leaks" that cause localized moisture and structural damage to ceiling panels in Malaysia's 80%-90% humidity.

• Handover Validation: For new projects, we provide the certified Duct Leakage Test (DLT) report required for project completion and Building Energy Intensity (BEI) labeling.
