In the 2026 Malaysian industrial and healthcare landscape, HEPA-Integrated AHU Refurbishment is a high-precision engineering intervention.
At EKG (Malaysia) SDN BHD, we transform legacy commercial AHUs into high-performance, clinical-grade assets.
HEPA integration is required for facilities pursuing MOH (Ministry of Health) accreditation or high-tech manufacturing compliance in KL.
99.99% Pathogen Barrier: Per DOSH ICOP IAQ 2026, sterile environments (operating theaters, labs, fabs) must maintain a "Bio-Secure" air path. HEPA refurbishment provides the primary defense against ultra-fine sub-micron particles.
Static Pressure Engineering: HEPA filters (H13/H14) introduce a "Pressure Penalty" (starting at 250 Pa).
MS 1525:2024 Airtightness: At high static pressures, any casing leak becomes "Energy Theft."
Before HEPA modules are integrated, the existing casing must be biologically stabilized through our proprietary protocol.
| Stage | Engineering Action | Purpose |
| I: HEPA Extraction | Industrial H13 HEPA vacuuming. | Removes legacy dust and fiberglass shards that would immediately clog new HEPA filters. |
| II: Microbial Lysis | pH-neutral enzymatic biocides. | Chemically ruptures bio-films and fungal roots in the old casing. |
| III: Thermal Disinfection | Vapor treatment at 120°C. | Sanitizes deep into panel joints and crevices to ensure a sterile substrate. |
| IV: ATP Validation | Bioluminescence swab testing. | Provides empirical proof of a 99.9% reduction in microbial activity before integration. |
We re-engineer the internal architecture of the AHU to handle high-efficiency filtration in tropical humidity.
V-Bank HEPA Frames: We install deep-pleat V-Bank frames to maximize surface area.
Fiber-Free Thermal Overhaul: We replace shedding fiberglass with Fiber-Free Closed-Cell Insulation. This eliminates the risk of fibers clogging the HEPA filters and prevents "The Sponge Effect" that leads to mold.
Silver-Ion (Ag+) Passivation: All internal surfaces are coated with a silver-ion antimicrobial finish. This provides a 24/7 active defense, ensuring the air remains sterile after it passes the HEPA filter.
A HEPA-integrated unit must satisfy the highest life-safety requirements of BOMBA 2026.
Class 0 Fire Rating: All integrated materials—from filter seals to insulation—are certified Class 0 (BS 476 Part 6 & 7) for flame spread and smoke toxicity.
Pressure Resilience: We verify that the refurbished casing can withstand the significant static pressure surge that occurs during an Automatic Fire Signal AHU Shut-off or smoke management cycle.
DOP/PAO Test Ports: We install built-in ports for Dispersed Oil Particulate (DOP) testing, allowing for rapid, leak-free validation of filter seals for your annual health and fire audits.
Technical Integrity: We are mechanical and T&C specialists, not just part-sellers.
GITA Sustainability: HEPA-integrated refurbishment is a recognized "Green" intervention.
Zero-Subcontractor Execution: Our KL-based team handles the entire process—from 4-Stage Decontamination to final HEPA Leak Testing—ensuring accountability and precision.
