In the 2026 engineering landscape of Malaysia, an AHU Mounting Setup is no longer just a mechanical task; it is a critical requirement for compliance with the Energy Efficiency and Conservation Act (EECA) 2024. Since the full enforcement of the act on January 1, 2025, every aspect of AHU mounting—from vibration isolation to plinth leveling—must be documented as part of the building's mandatory energy performance records.
At EKG (Malaysia) SDN BHD, we ensure that your mounting setup is engineered to be Sterile, Silent, and Statutory-Compliant.
Before the unit is positioned, the structural base must be verified against the LOD 400 BIM design.
Plinth Levelness: The concrete housekeeping pad must be perfectly flat (tolerance within +/- 2mm). In 2026, we utilize rotary laser levels to confirm this, as an uneven base causes frame torque, leading to air leakage—a form of "Energy Theft" under the EECA.
Static Load Capacity: We verify that the rooftop slab or plant room floor can support the operating weight of the AHU (including water-filled coils). This is especially critical for Grade-A developments where floor-to-floor heights are optimized.
Clearance Mandates: Following MS 1525:2024, mounting must provide a minimum clearance (typically equal to the unit width) on the service side to allow for coil pull-out and filter changes.
To achieve the premium NC 30-35 noise profile required for 2026 office environments, we utilize a three-tier isolation strategy.
| Component | Engineering Standard | Purpose |
| Inertia Bases | Concrete-filled steel frames. | Adds mass to lower the system's natural frequency and dampen low-end thrum. |
| Spring Isolators | High-deflection (25mm–50mm). | Decouples mechanical vibration from the building structure with 95%+ efficiency. |
| Flexible Connections | Braided hoses & rubber flanges. | Prevents noise from "bridging" into the chilled water piping or ductwork. |
Proper mounting is the primary defense against "Sick Building Syndrome."
Precision 1:100 Slope: We ensure the unit is mounted with a slight, calculated pitch toward the drain outlet. This ensures zero stagnant water in the SUS 304/316 stainless steel drain pan—a mandatory requirement for DOSH (JKKP) hygiene audits.
Seismic Restraints: For high-rise installations in areas with potential seismic activity, we integrate snubbers into the mounting setup to prevent the unit from shifting while maintaining acoustic isolation.
Base Frame Airflow: The unit is raised off the floor to prevent moisture buildup underneath the casing, protecting the TB2 Thermal Break integrity and preventing floor-level corrosion.
Under the July 2025 Malaysian BIM Mandate, your mounting setup must be digitally verified.
LOD 500 Digital Twin: We scan the as-installed mounting to ensure it matches the digital design. This provides the "As-Built" proof required for the mandatory 5-year periodic energy audit.
EnMS Hookup: All mounting sensors (such as vibration monitors) are integrated into your Energy Management System (EnMS) to provide real-time health tracking of the mechanical asset.
GITA Documentation: Proper mounting is a "Good Engineering Practice" benchmark required for your business to claim the 100% Green Investment Tax Allowance.
Technical Integrity: Our mounting setups are overseen by mechanical engineers who specialize in the thermodynamics and acoustics of tropical air treatment.
Zero-Subcontractor Model: We manage the rigging, plinth verification, and isolator setup internally to ensure no detail is missed.
Audit-Ready Handover: We provide the certified reports needed to protect your building's energy license and secure your Energy Intensity Label.
