In the high-performance building landscape of 2026 Kuala Lumpur, Duct Leakage Testing (DLT) is a critical requirement for meeting the Energy Efficiency & Conservation Act (EECA) 2024. This act, which came into full force on January 1, 2025, mandates that commercial and industrial buildings optimize their "Building Energy Index" (BEI). A leaking duct system is a primary source of illegal energy waste, often causing fans to run 33% harder just to compensate for air lost in the ceiling plenum.
As part of our Duct Leakage Testing category, EKG provides the certified Duct Air Leakage Testing (DALT) and forensic diagnostics required to ensure your facility is airtight, compliant, and energy-efficient.
Under the latest MS1525:2024 and EECA standards, duct integrity is no longer optional:
The 3% Leakage Limit: Modern Malaysian standards typically require that total system leakage does not exceed 3% of the design airflow. For high-pressure systems, we target SMACNA Class A (the highest tier of sealing).
Maximum Demand (MD) Impact: By sealing leaks, we reduce the load on your AHU fans. This allows your VSD to drop the motor frequency ($Hz$), directly lowering your monthly TNB Maximum Demand charges.
Condensation Control: In KL’s 90% humidity, air leaks cause "Ceiling Sweating." Our testing prevents the moisture buildup that leads to mold—ensuring you stay below the DOSH ICOP IAQ limit of 500 cfu/m³.
We utilize the latest 2026-spec equipment, such as the Kanomax DALT 6905, to provide automated, high-precision testing:
Pressurized Sectional Testing: We isolate sections of the ductwork using inflatable plugs and measure the exact $L/s$ leakage rate at your system's "Shut-Off Pressure."
Ultrasonic Leak Pinpointing: For inaccessible risers in KL high-rises, we use ultrasonic "Pingers" to locate microscopic gaps in mastic seals or gaskets without tearing down the ceiling.
Thermal Infrared Audits: Using FLIR Thermal Cameras, we identify "Cold Plumes" in the ceiling void, providing visual proof of where your cooling Ringgits are escaping.
Smoke Injection Verification: We use non-toxic artificial smoke to visually confirm seal integrity during final commissioning or for BOMBA smoke-spill system audits.
A certified Duct Leakage Test is the foundation of your building's Energy Intensity Label:
Optimizing the VSD Setpoint: Most buildings in the Klang Valley over-pressurize their ducts. We find the lowest possible setpoint that satisfies all zones, capturing maximum Cube Law energy savings.
EECA 2024 Documentation: We provide the "Certified Leakage Report" required for your Registered Energy Auditor (REA) to submit to the Energy Commission (ST).
Extended Asset Life: Reducing "Static Stress" on your AHU lowers the operating temperature of motor windings and extends the life of your bearings and belts.
| Standard / Class | Application (2026 KL) | EKG Testing Accuracy |
| SMACNA Class 3 | High-Rise Supply / Risers | $\pm 2.5\%$ Flow Precision |
| DW/143 Class B | Commercial AHU Branching | Full Pressure Profile Map |
| MS1525:2024 | General Energy Compliance | Certified REA Reporting |
| Cleanroom / Lab | High-Integrity HEPA Paths | Aerosol Particle Integrity |
Mechanical Restoration Path: We don't just "read a meter"; we are experts in Mechanical Fan Overhauls. We ensure your AHU is physically capable of the performance targets we measure.
VFD-Energy ROI Projection: We use digital power loggers to provide a baseline report, proving exactly how much your energy bill will drop once leaks are sealed.
Rapid Response: Based in the heart of KL, we specialize in "After-Hours" testing for occupied towers (KLCC, TRX, PJ) to ensure zero noise disruption for tenants.
34 Years of Depth: As a Malaysian HVAC leader, we bridge the gap between legacy infrastructure and 2026 smart-building requirements.
