In the tropical climate of Kuala Lumpur and Selangor, "High Volume Ventilation" is the engineering practice of moving massive quantities of air ($CMH$ - Cubic Meters per Hour) to combat heat gain, remove industrial pollutants, and maintain indoor air quality (IAQ). For large-scale facilities like shopping malls, warehouses, and central kitchens, standard air conditioning is often too expensive to run 24/7 without a high-efficiency ventilation strategy.
EKG M&E Sdn Bhd specializes in the design, installation, and VSD-controlled optimization of high-volume systems to ensure your facility "breathes" efficiently while keeping TNB costs under control.
As an HVAC and Clean Air Specialist, we deploy specific mechanical assets based on the "Static Pressure" and volume requirements of your building.
The most energy-efficient way to move air in large open spaces.
The Physics: A single 7.3m fan can move over $300,000$ CMH, creating a "perceived cooling" effect of 3°C to 5°C through evaporative cooling on the skin.
Thermal Destratification: It pushes the hot air trapped at the ceiling downwards to be exhausted, preventing "Heat Pockets."
For systems requiring "Force-Draft" or "Induced-Draft" ventilation through ductwork or filtration banks.
Axial Fans: Best for moving air in a straight line with low resistance (e.g., general warehouse exhaust).
Centrifugal Fans: Essential for "High Resistance" environments like Ecology Units or chemical scrubbers, where the fan must "push" air through multiple filter stages.
Installed at the highest point of the roof to utilize the "Stack Effect."
Natural Exhaust: As air heats up, it rises and escapes through the ridge, pulling cooler air in from the ground level.
High volume ventilation isn't just about blowing air out; it’s about managing the Building Pressure.
Variable Frequency Drive (VFD) Modulation:
Running large motors at 100% speed 24/7 is a major waste of energy. We program the VSD/VFD to ramp the fans up or down based on real-time temperature or CO2 sensors. This reduces mechanical wear and slashes electricity bills.
Positive Pressure Shield:
In clean environments (like food processing or guest dining areas), we calibrate the Make-up Air (MUA) to be slightly higher than the exhaust. This creates Positive Pressure, which physically prevents KL street dust and humid "unconditioned" air from entering through doors and loading bays.
| Metric | Natural Ventilation | Standard High-Speed Fans | EKG M&E High Volume System |
| Airflow Volume | Low (Weather dependent). | Moderate (Localized). | High (System-wide). |
| Energy Efficiency | 100% (Passive). | Low (High power/fan). | High (VFD Optimized). |
| Cooling Effect | Minimal. | High (Turbulent/Noisy). | High (Uniform/Quiet). |
| IAQ Control | No filtration. | No filtration. | Integrated (ESP/Carbon). |
Airflow Balancing and Commissioning: We perform a professional Duct Traverse and Static Pressure Audit to prove your facility is achieving its design Air Change Rate (ACR).
Total System Synchronization: We ensure your ventilation is interlocked with the Fire Alarm (BOMBA) for emergency smoke spill control and the BMS for real-time monitoring.
Klang Valley Strategic Support: Based in Kuala Lumpur, we provide turnkey design and scheduled maintenance for logistics hubs, manufacturing plants, and central kitchens.
