In the tropical climate of Malaysia, Thermal Break AHU Casing is no longer just a premium feature; it is a mechanical necessity for meeting the Building Energy Intensity (BEI) targets mandated by EECA 2024. Without a proper thermal break, an AHU acts as a "thermal bridge," allowing heat from the mechanical room to migrate into the cold air stream, which directly inflates your chiller load and spikes your electricity bills.
At EKG (Malaysia) SDN BHD, we engineer our AHUs to TB2 thermal break standards, ensuring your infrastructure supports a 4-star or 5-star energy rating.
A thermal bridge occurs when highly conductive materials (like the aluminum or steel frames of an AHU) connect the cold interior to the warm exterior.
Energy Loss: In a standard unit, the frame "sweats" because it is cooled by the internal air. This condensation represents wasted cooling energy that should have been delivered to your office or factory floor.
TB2 Rated Integrity: Our TB2 casing utilizes high-density, non-metallic thermal breaks (usually reinforced polyamide) that physically decouple the inner skin from the outer skin. This stops heat migration in its tracks.
Under the Energy Efficiency and Conservation Act 2024, every kilowatt matters. Thermal break casing contributes to a lower BEI in three ways:
Reduction in "Parasitic" Heat Gain: By preventing ambient heat from entering the air stream, the AHU maintains the design "Supply Air Temperature" (SAT) more efficiently. The chiller plant doesn't have to compensate for heat gained through the casing.
Prevention of Condensation & Mold: Sweating units lead to wet floors and mold growth. This not only violates DOSH/JKKP health standards but also degrades internal insulation, which increases the thermal conductivity of the unit over time.
Enhanced SFP Performance: Because the air stays at the intended temperature and density, the IE5 EC Fan Array can operate at its Best Efficiency Point (BEP) without having to ramp up to overcome density changes or extra load.
| Feature | Standard Double-Skin | EKG TB2 Thermal Break |
| Heat Transfer | High (Metallic Bridges) | Ultra-Low (Decoupled Skins) |
| Condensation Risk | High in 80%+ Humidity | Near-Zero (Anti-Sweat) |
| Insulation Core | Fiberglass (Sags over time) | High-Density PU Foam (Rigid) |
| Airtightness | L3 Leakage | L1 Precision Sealed |
| BEI Impact | Increases Chiller Load | Optimizes Chiller Efficiency |
Smart placement is key to maximizing the performance of a thermal break unit:
Acoustic Buffer Placement: We position TB2 units in well-ventilated AHU rooms. Even if the room temperature rises slightly, the thermal break ensures the internal air stays at 7°C – 12°C with zero heat gain.
3D BIM Precision: We use BIM to ensure that the AHU frame is not in direct contact with structural steel or concrete slabs. We utilize thermal isolation pads under the base frame to complete the "thermal envelope."
To maintain your energy star rating in 2026, you must provide verifiable data to your Registered Energy Manager (REM).
EnMS Integrated Sensors: Our units include surface temperature sensors on the casing. This data is fed into your Energy Management System (EnMS) to prove that the casing is performing to its TB2 design and not contributing to "thermal drift."
L1 Leakage Certification: Thermal break integrity is only effective if the unit is airtight. Our units are certified to L1-class leakage, ensuring that zero "cold energy" escapes through the panel joints.
Technical Integrity: we provide the Psychrometric Reports and $U$-value calculations needed to justify your BEI reduction strategies to the Energy Commission.
BOMBA-Compliant Safety: All internal insulation and thermal break materials are fire-rated (Class 0 or B1) for peace of mind in commercial environments.
Precision Fabrication: Every unit is custom-engineered in our facility to ensure the thermal break continuity is never broken by fasteners or hinges.
