In the urban sprawl of Kuala Lumpur and Selangor, where commercial space is at a premium, Rooftop Filtration Units (often referred to as Ecology Units or Pollution Control Units) are the standard M&E solution for managing large-scale kitchen exhaust and industrial emissions. By moving the filtration stack to the roof, you save internal floor space while ensuring that "Clean Air" is discharged safely away from building air intakes and neighboring windows.
EKG M&E Sdn Bhd specializes in the engineering, structural integration, and DOE-compliant maintenance of these heavy-duty rooftop assets.
A rooftop unit must be more than just a filter box; it must be an "armored" M&E system capable of withstanding KL's tropical climate.
To achieve "Clear Stack" discharge, we utilize a cascading filtration logic:
Pre-Filtration: High-capacity G4 filters to trap dust and large grease particles.
Electrostatic Precipitator (ESP): High-voltage cells that ionize and capture 95%+ of sub-micron smoke.
Activated Carbon: Final odor neutralization using molecular adsorption to trap VOCs.
Exposed to the intense Malaysian sun and monsoon rains, these units require specialized protection:
Double-Skin Housing: To prevent internal condensation (which ruins carbon filters) and reduce solar heat gain.
IP66 Rated Controls: We ensure the Variable Frequency Drive (VFD) and control logic are housed in weather-shielded enclosures.
Corrosion Resistance: Utilizing powder-coated galvanized steel or aluminum to prevent rust in high-humidity environments.
As an HVAC and Clean Air Specialist, we ensure your rooftop unit is perfectly synchronized with the rest of the building.
VFD Optimization & Static Pressure:
Rooftop units often sit at the end of long vertical duct runs. We program the VFD to overcome this "Static Pressure" while adjusting for filter loading. This ensures a constant Air Change Rate (ACR) at the kitchen hoods below.
Building Pressure Management:
A powerful rooftop extractor can turn a building "Negative," sucking in humid KL air through the lobby doors. We calibrate the unit to match your Fresh Air Supply, maintaining a slight Positive Pressure in the occupied zones to keep odors and street dust out.
Vibration Isolation:
To prevent mechanical noise from traveling through the building structure to the floors below, we utilize spring-loaded vibration isolators and flexible duct connectors.
| Feature | Standard Inline Fan | EKG M&E Rooftop Filtration Unit |
| Smoke Removal | None (Visible plume). | High (95% - 99% Efficiency). |
| Odor Control | None (Smells linger). | Total (Neutralized via Carbon). |
| Maintenance | Difficult (Indoor access). | Easy (Rooftop service access). |
| Compliance | Basic Health Codes. | DOE / DBKL / MBPJ / BOMBA. |
Turnkey Commissioning: We provide professional Duct Traverse and Static Pressure reports post-installation to verify that your rooftop discharge meets all local environmental standards.
Klang Valley Strategic Support: Based in Kuala Lumpur, we provide turnkey design, structural mounting, and scheduled "Clean Air" audits for shopping malls, hotels, and central kitchens.
Safety Interlocks: Our units are fully integrated with the Building Management System (BMS) and fire alarm, ensuring instant shutdown in the event of an emergency.
