In the 2026 Malaysian mechanical sector, a Leaking Air Handler is categorized as a high-priority structural failure. Under the Energy Efficiency and Conservation Act (EECA) 2024, moisture escaping an AHU is the primary driver of "The Sponge Effect"—where water wicks into the AHU Box insulation, leading to structural rot and high Building Energy Intensity (BEI).
At EKG (Malaysia) SDN BHD, we provide forensic leak remediation that transitions your unit from a failing enclosure back into a dry, high-performance pressure vessel that satisfies DOSH (JKKP) 2026 hygiene standards.
A leaking AHU is rarely just a plumbing issue; it is typically a failure of the unit's structural or thermodynamic integrity.
Condensate Path Failure: Often caused by "The White Slime" (bio-films) or improper sloping. We utilize laser-guided leveling to restore a 1:50 pitch to the AHU Base Frame, ensuring gravity-fed drainage.
Thermal Bridge Failure (Casing Sweat): When the AHU Moisture Barrier or insulation fails, the external casing drops below the dew point in KL's 90%+ humidity. We install TB2-standard thermal breaks to decouple the inner and outer skins.
Airtightness Breach: High static pressure from IE5 EC Fan Walls can force moisture through compromised gaskets. We perform AC Unit Strengthening by installing High-Tensile G90 stiffeners to eliminate "Panel Panting."
Remediating a leaking AHU is a prerequisite for passing mandatory 2026 building health and energy audits.
DOSH 2026 (IAQ): Damp insulation is a breeding ground for fungal colonies. Our "Zero-Leak" protocol keeps indoor microbial counts below the statutory 1000 CFU/m³ limit.
SFP Efficiency (EECA 2024): Air and moisture leaks increase the motor's workload. A sealed unit ensures your Specific Fan Power (SFP) stays within the statutory 1.6 kW/m³/s limit.
BOMBA 2026 (Fire Safety): All sealing and insulation materials we utilize are certified Class 0 (BS 476 Part 6 & 7) for zero flame spread and minimal smoke toxicity.
We follow a forensic mechanical workflow to ensure your repair is both audit-ready and durable.
| Stage | Engineering Action | Performance Outcome |
| I: Forensic Leak Audit | FLIR thermal imaging and ultrasonic thickness testing of the pan. | Pinpoints hidden "Cold Spots," metal thinning, and structural breaches. |
| II: Mechanical Stabilization | Controlled jacking and installation of G90 structural shims. | Restores the designed drainage pitch and neutralizes frame sagging. |
| III: Bio-Security Upgrade | Application of Silver-Ion (Ag+) antimicrobial structural liners. | Re-establishes a seamless, 100% waterproof, and biologically inert basin. |
| IV: T&C Validation | Post-repair flood testing and pressure decay verification. | Provides the certified technical dossier required for your Registered Energy Manager (REM). |
To ensure the leak does not recur in Malaysia's tropical climate, we passivate the assembly and add automated sentinels.
Silver-Ion (Ag+) Passivation: All internal seams are treated with antimicrobial agents. This disrupts pathogen metabolism, preventing the bio-film blockages that cause condensate overflows.
Automatic High-Level Float Switches: We integrate industrial-grade switches that trigger an automated shutdown of the fan array if water levels rise, preventing catastrophic ceiling damage.
Fiber-Free Casing Restoration: We replace moisture-wicking legacy fiberglass with Fiber-Free Closed-Cell Insulation. This ensures that even if a seal is momentarily breached, the insulation cannot act as a "Sponge."
Technical Integrity: We are mechanical and T&C specialists. We focus on the thermodynamic and structural stabilization of your assets through precision engineering.
Audit-Ready Reporting: Following every project, we provide a Structural Integrity & Leak Validation Report, essential for your annual building audits and ESG reporting.
GITA Sustainability: HVAC structural repair and leakage restoration are recognized "Green" interventions, qualifying for the 100% Green Investment Tax Allowance (GITA).
