In the 2026 Malaysian mechanical sector, AC Drain Pan Repair is a critical engineering intervention for moisture management and indoor air quality. Under the Energy Efficiency and Conservation Act (EECA) 2024, standing water within an AHU is categorized as a primary cause of "The Sponge Effect"—where moisture wicks into the insulation, causing structural rot and casing "sweat."
At EKG (Malaysia) SDN BHD, we provide structural repairs that transition your drain pan from a corroded, leaking vessel back into a sterile, high-performance component, ensuring your unit stays compliant with DOSH (JKKP) 2026 hygiene standards.
The drain pan is the most vulnerable component in the AHU Box due to constant exposure to cold condensate and atmospheric oxidation.
Pitting & Perforation Remediation: In KL's high humidity, galvanized steel pans often suffer from pitting. We mechanically de-scale the oxidation and apply industrial-grade, fiber-reinforced polymers to restore the pan's watertight integrity.
Thermal Break Restoration: A leaking pan allows moisture to bypass the AHU Moisture Barrier, leading to internal frame rot. Our repair process includes re-sealing the interface between the pan and the AHU Frame using non-conductive, antimicrobial mastics.
Structural Strengthening: For pans that have sagged, we install High-Tensile G90 steel auxiliary supports to prevent "Pooling Zones," which are the leading cause of bio-film accumulation.
A professional drain pan repair is a prerequisite for passing mandatory 2026 building health and energy audits.
Pathogen Exclusion (DOSH 2026): Standing water in a corroded pan is a breeding ground for Legionella and fungal colonies. Our repair process ensures the surface is non-porous and "Easy-Clean," keeping microbial counts below the 1000 CFU/m³ limit.
Specific Fan Power (SFP) Stability: When moisture escapes the pan and enters the insulation, it increases the unit's weight and can lead to casing deformation. By keeping the unit dry, we maintain the unit’s airtightness and ensure your SFP stays within the statutory 1.6 kW/m³/s limit.
Fire Safety (BOMBA 2026): All EKG repair materials, including waterproof membranes and coatings, are certified Class 0 (BS 476 Part 6 & 7) for zero flame spread.
We utilize a mechanical "Handshake" to ensure every repair is both durable and audit-ready.
| Stage | Engineering Action | Performance Outcome |
| I: Forensic Leak Audit | Flood testing and ultrasonic thickness testing of the pan metal. | Pinpoints the exact coordinates of structural breaches and metal thinning. |
| II: Mechanical Prep | Mechanical de-scaling (SSPC-SP2/SP3) and solvent cleaning. | Removes all bio-films and oxidation to ensure a molecular bond for new coatings. |
| III: Structural Lining | Application of multi-layer, antimicrobial, and 100% waterproof structural epoxy. | Re-establishes a seamless, high-tensile basin that reinforces the AHU Base Frame. |
| IV: T&C Validation | Post-repair flood testing and drainage pitch verification. | Provides empirical proof of integrity for your 2026 Registered Energy Manager (REM). |
To ensure the pan remains biologically inert in Malaysia's tropical climate, we passivate the surface.
Silver-Ion (Ag+) Passivation: Our repair coatings are infused with Silver-Ion technology, which actively disrupts the metabolism of pathogens on contact, preventing the formation of "Slime" and bio-films.
Hydrophobic Surface Energy: The coating is engineered with low surface tension, allowing condensate to bead and roll quickly toward the drain outlet, even at low sloping angles.
Vibration Damping: The structural liner acts as a vibration dampener, neutralizing the mechanical harmonics of the fan array that can lead to seal fractures in the pan corners.
Technical Integrity: We are mechanical and T&C specialists. We focus on the thermodynamic and structural stabilization of your assets through precision chemistry.
Audit-Ready Reporting: Following every repair, we provide a Drainage Integrity & Performance Validation Report, essential for your annual building audits.
GITA Sustainability: AHU structural repair and drain pan modernization are recognized "Green" interventions, qualifying for the 100% Green Investment Tax Allowance (GITA).
