In the 2026 Malaysian industrial sector, Antimicrobial Internal AHU Lining Upgrades are the primary technical defense against "Sick Building Syndrome." Under the DOSH (JKKP) 2026 Hygiene Codes and the Energy Efficiency and Conservation Act (EECA) 2024, the internal cleanliness of an AHU is no longer just a maintenance concern—it is a statutory performance metric.
Traditional porous linings (like aged fiberglass) act as "biological reservoirs" that trap moisture and nutrients, breeding mold, yeast, and bacteria. At EKG (Malaysia) SDN BHD, we upgrade these legacy systems with Silver-Ion infused, non-porous linings to ensure your facility remains Pathogen-Free and Statutorily Compliant.
Upgrading to antimicrobial linings is essential for passing mandatory 2026 building health audits.
IAQ Compliance (DOSH 2026): Per the latest Indoor Air Quality codes, any AHU surface showing a "Bio-Film" or fungal colonization is a direct violation. Antimicrobial upgrades provide a 24/7 active defense, preventing the distribution of pathogens into the office air stream.
MS 1525:2024 Standards: Under the updated Malaysian Standard, internal linings must be non-shedding and resistant to microbial growth. We utilize linings that are inherently hydrophobic and chemically treated to neutralize microbes on contact.
BEI Star Rating: Bio-films on internal linings increase surface roughness and air resistance. A smooth, antimicrobial lining ensures laminar air flow, helping your IE5 EC Fan Wall stay within the statutory 1.6 kW/m³/s SFP limit.
We treat the AHU interior as a medical-grade environment, utilizing advanced polymer and metallic-ion science.
| Upgrade Type | Technical Specification | Engineering Purpose |
| Silver-Ion (Ag+) Encapsulation | High-tack polymer infused with bio-active silver ions. | Provides a permanent, non-leaching antimicrobial surface. |
| Non-Porous EPDM Lining | Closed-cell elastomeric sheets (Class 0 Fire Rated). | Eliminates the "Sponge Effect" and prevents moisture absorption. |
| Stainless Steel (316L) Skin | Anti-corrosive, medical-grade internal skinning. | The ultimate "Sanitary Shield" for cleanroom and hospital AHUs. |
| Antimicrobial Mastic Sealing | UV-stable, biocidal MS Polymer sealants. | Ensures that "Micro-Leaks" at seams do not become mold-breeding sites. |
The EKG approach targets the intersection of microbiology and acoustics.
Bio-Active Neutralization: Our silver-ion linings work by disrupting the cell membranes of bacteria and fungi that land on the surface. This prevents the formation of bio-films, ensuring that the air path remains sterile even in Kuala Lumpur’s 90%+ humidity.
Fiber-Lock Integration: For units where old fiberglass cannot be fully removed, we perform Surface Disinfection & Lining Sealant protocols using antimicrobial encapsulants. This locks down fibers and provides a "Self-Sanitizing" outer shell.
Acoustic Damping Balance: We utilize "Acoustically Transparent" antimicrobial coatings. These specialized layers protect the surface from germs without filling the microscopic voids needed for sound absorption, ensuring the unit maintains its NC 30-35 signature.
Upgrade materials must satisfy the life-safety requirements of BOMBA (JBPM) 2026.
Class 0 Fire Rating: Every antimicrobial lining and sealant used by EKG is certified Class 0 (BS 476 Part 6 & 7). This is a non-negotiable requirement for your annual Fire Certificate (FC) renewal.
Static Pressure Resilience: The lining bond is tested to ensure it does not "peel" or delaminate during the high-pressure surges of an Automatic Fire Signal AHU Shut-off.
BOMBA Audit Readiness: We provide the fire-retardant certification and microbial clearance logs (including ATP swab tests) required by JBPM and DOSH inspectors.
Technical Integrity: We are mechanical and IAQ specialists, not just general contractors. We focus on the long-term structural, energy, and biological health of your AHU assets.
Audit-Ready Reporting: Following the upgrade, we provide a Microbial Validation Report, essential for your Registered Energy Manager (REM) to prove proactive IAQ management.
GITA Sustainability: Antimicrobial upgrades are a recognized "Green" intervention. We provide the technical data required for your 100% Green Investment Tax Allowance (GITA) claims.
