At EKG (Malaysia) SDN BHD, an Energy Saving AHU is designed as a high-performance engine for your building. Under the EECA 2024 and MS 1525 standards, the Air Handling Unit is the single most important factor in reducing your Building Energy Intensity (BEI) and securing a mandatory 3-star to 5-star energy rating.
We focus on a "Zero-Waste" engineering approach, ensuring every watt of electricity is converted into usable cooling comfort.
The fan motor is the largest energy consumer in any AHU. We eliminate traditional mechanical losses through two primary upgrades:
EC (Electronically Commutated) Plug Fans: Standard belt-driven fans lose 5% to 12% of their energy to friction and slippage. We use Direct-Drive EC Fans (IE4/IE5), which integrate the motor and fan into a single efficient unit.
Load Matching: Unlike AC fans that often run at 100% regardless of need, EC fans modulate their speed in real-time.
In Malaysia's high-humidity environment, energy is frequently lost through the "skin" of the AHU before it reaches your office.
TB2 Thermal Bridging Factor: We utilize advanced composite thermal breaks in our unit frames. This prevents "cold bridging," which stops the unit from "sweating" (condensation) and prevents heat from the mechanical room from leaking into the cold air stream.
L1 Leakage Class: Our units are precision-sealed to meet the highest international standards. Preventing treated air from escaping the unit is a critical step in lowering your Specific Fan Power (SFP) to below the compliant 1.6 kW per m³/s threshold.
An energy-saving AHU must respond intelligently to the building's environment:
Demand-Controlled Ventilation (DCV): By integrating CO2 and occupancy sensors, the AHU only works at peak capacity when people are actually in the room. This "smart" modulation is essential for meeting the mandatory Energy Management System (EnMS) requirements of the EECA 2024.
Energy Recovery Wheels (ERW): We often integrate Thermal Wheels that "recycle" the cool, dry air from your exhaust to pre-condition the hot, humid intake air. This can reduce the total cooling load on your central chillers by up to 30%.
Technical Integrity: We provide full AHU Energy Audits to calculate exactly how much your new unit will lower your BEI score, providing data for your mandatory reporting.
3D BIM Coordination: We use 3D modeling to design "clash-free," aerodynamically optimized duct paths. This reduces External Static Pressure (ESP), allowing your fan to operate at its most efficient point.
BOMBA-Compliant Safety: All materials—from high-performance insulation to motor casings—are vetted for fire safety (Class 0 or B1).
