In the 2026 Malaysian mechanical sector, AHU Panel Joint & Gasket Resealing is a high-precision intervention designed to eliminate "Energy Bleed." Under the Energy Efficiency and Conservation Act (EECA) 2024, air leakage through perished gaskets or failing panel joints is a primary contributor to high Building Energy Intensity (BEI). A leaking AHU casing forces the VFD-driven AHU to increase its fan speed to maintain downstream static pressure, directly violating statutory Specific Fan Power (SFP) limits.
At EKG (Malaysia) SDN BHD, our resealing protocols utilize aerospace-grade materials and industrial compression techniques to ensure your AHU achieves a hermetic seal that satisfies DOSH (JKKP) and MS 1525:2024 standards.
Resealing joints and gaskets is essential for passing mandatory 2026 building energy audits.
Airtightness (Airtightness Class 6): Per MS 1525:2024, AHU casings must maintain SMACNA Seal Class A. Resealing ensures that the "Box" achieves ATC 6 compliance, preventing the wasted power associated with "Ceiling Void Cooling."
Condensation Control: Under DOSH 2026 hygiene codes, a leaking joint allows cold air to escape, causing the exterior panel to "sweat." This localized moisture leads to mold growth and "Base Rot," which can trigger a statutory health violation.
SFP Benchmark Restoration: By sealing the joints, we ensure the air path remains pressurized and efficient, keeping the SFP within the statutory 1.6 kW/m³/s limit.
We treat the AHU joint as a critical pressure boundary, utilizing UV-stable and fire-rated materials.
| Resealing Phase | Technical Action | Purpose |
| Gasket Replacement | Installation of high-density, dual-fin EPDM gaskets. | Provides a zero-leakage compression seal for access doors. |
| Joint Injection | Injecting high-tack MS Polymer into failing panel seams. | Bridges structural gaps caused by "racking" or vibration. |
| Thermal Break Sealing | Application of non-conductive sealant to panel-to-frame interfaces. | Eliminates "Cold-Bridging" and prevents exterior condensation. |
| Fastener Encapsulation | Capping of panel screws with waterproof, elastomeric liquid caps. | Prevents "Pin-Hole" leaks and screw-head corrosion. |
The EKG approach to resealing focuses on the physics of the casing to maximize the efficiency of your IE5 EC Fan Wall.
Compression Calibration: We verify the AHU Door Seal & Latched Hardware Replacement to ensure gaskets are compressed by exactly 25–30%. Over-compression can damage the gasket, while under-compression leads to air "whistling."
Laminar Flow smoothing: During AHU Body Restoration, we ensure that internal joint sealants are applied flush. This reduces air turbulence at the panel interfaces, lowering the internal static resistance of the unit.
Acoustic Containment: Air leaks are also "Sound Leaks." By achieving a hermetic seal at the panel joints, we ensure the unit maintains its NC 30–35 acoustic signature, protecting the office environment from mechanical hum.
Resealing materials must satisfy the life-safety requirements of BOMBA (JBPM) 2026.
Class 0 Fire Rating: Every sealant and gasket used by EKG is certified Class 0 (BS 476 Part 6 & 7). This is mandatory to ensure the casing does not release toxic thick smoke or contribute to flame spread during a fire.
Pressure Spike Resilience: The resealed joints are tested to withstand the sudden static pressure surge that occurs during an Automatic Fire Signal AHU Shut-off, ensuring the casing remains intact.
BOMBA Audit: JBPM officers verify the "smoke-tight" integrity of the AHU enclosure during the annual Fire Certificate (FC) audit to ensure smoke cannot bypass the Motorized Fire Dampers (MFDs).
Technical Integrity: We are mechanical and T&C specialists, not just general waterproofers. We understand how internal pressures interact with external seals.
Audit-Ready Reporting: Following the resealing, we provide an AHU Casing Air Leakage Validation Report, which is a vital document for your Registered Energy Manager (REM).
BEI Optimization: By eliminating leaks, we directly lower your building's energy footprint. Resealing is one of the highest-ROI interventions for improving your 2026 Energy Intensity (BEI) score.
