In the 2026 Malaysian engineering landscape, a Ductwork Integrity Test is the definitive procedure for validating the structural and airtight performance of an HVAC system. Under the Energy Efficiency and Conservation Act (EECA) 2024 and the DOSH ICOP IAQ 2026, "Integrity" refers to the system's ability to remain hermetically sealed and structurally sound under operational pressure.
At EKG M&E Sdn Bhd, we apply 34 years of mechanical depth to verify your ductwork, ensuring it acts as a high-performance asset rather than an "Energy Leak" in your Building Energy Index (BEI).
An integrity test evaluates the system across three critical mechanical domains:
Airtightness (Leakage Control): Using the DW143 Standard, we measure the volume of air escaping from joints and seams. In 2026, maintaining Airtightness Class 6 (ATC 6) is essential to prevent cooled air from being wasted in ceiling voids, which can reduce fan energy consumption by up to 30%.
Structural Stability: We verify that the duct gauge, hangers, and supports comply with SMACNA or MS 1525:2024 standards. This ensures the ductwork can withstand the "Static Pressure" of modern high-efficiency fans without bowing or vibrating.
Thermal & Microbial Barrier: We test the integrity of internal and external insulation. Compromised insulation leads to "Ghost Cooling" (heat gain) and serves as a breeding ground for mold, which can cause a failed DOSH 2026 air quality audit.
We utilize a medical-grade diagnostic process to generate a "Digital Health Certificate" for your infrastructure:
Positive/Negative Pressure Testing: Using calibrated PANDA testers, we pressurize isolated sections to the design operating limit. We record the pressure decay and leakage rate in $l/s/m^2$ for your Registered Energy Manager (REM).
Forensic Smoke Verification: For critical fire zones or smoke spill systems, we deploy Non-Toxic Smoke Generators. The escaping smoke visually identifies any breach in the fire-rated sealants, essential for your annual BOMBA Fire Certificate (FC) renewal.
Robotic Internal Audits: We deploy high-definition camera robots to inspect internal seams and "Smart Actuator" interfaces. This proves that the "Injection Path" is clean and the mechanical components are not seizing.
Ultrasonic Leak Detection: In risers or shafts where visual access is restricted, we use ultrasonic sensors to "hear" high-frequency air leaks that indicate a structural seal failure.
At EKG M&E Sdn Bhd, our integrity reports are designed to satisfy all 2026 Malaysian regulatory bodies:
| Integrity Metric | Regulatory Significance |
| Leakage in $l/s/m^2$ | Mandatory for EECA 2024 5-Star Energy Label. |
| Microbial CFU Counts | Required to pass DOSH ICOP IAQ 2026 health audits. |
| Static Pressure ($Pa$) | Verified against original M&E design specifications. |
| BOMBA Performance | Proof of containment for smoke extract systems. |
| VFD Optimization Data | Evidence of reduced $kWh$ consumption for TNB audits. |
34 Years of Engineering Depth: Based in Kuala Lumpur, we understand the mechanical physics of high-rise plants. We ensure that integrity testing never damages your BMS sensors or internal duct seals.
Turnkey Documentation: We provide a comprehensive digital audit package containing robotic footage, calibrated test logs, and engineering certificates.
Total 3D BIM Coordination: For new projects, we identify "Integrity Test Zones" in 3D to ensure testing is fast, accurate, and non-disruptive to other trades.
