In the high-density urban and industrial environments of Kuala Lumpur and Selangor, proper ventilation is the lifeblood of a cooling tower. Ventilation refers to the managed movement of air through the tower to facilitate evaporation. If airflow is restricted by poor placement, clogged louvers, or fan inefficiency, the "Wet-Bulb" temperature inside the tower rises, causing the Chiller to work harder and increasing your TNB electricity costs.
EKG M&E Sdn Bhd specializes in Airflow and Ventilation Optimization, ensuring your tower has the static pressure and volume required to meet design heat rejection targets.
As an HVAC and Clean Air Specialist, we manage the two primary ways air moves through a cooling tower:
Induced Draft Ventilation: Fans are located at the top (discharge) of the tower, pulling air upwards through the infill. This is the most common setup in KL commercial buildings as it provides high exit velocity, reducing the risk of "Recirculation" (re-inhaling hot exhaust air).
Forced Draft Ventilation: Fans are located at the base or side, pushing air into the tower. These are ideal for confined spaces or indoor installations where high static pressure is needed to overcome ductwork resistance.
We use precision instrumentation to identify "Air Dead Zones" and mechanical bottlenecks:
Recirculation Analysis: In crowded areas like Bandar Sunway or KLCC, towers are often placed too close together. We measure if the hot discharge air is being sucked back into the intake louvers, which can destroy cooling capacity by up to 20%.
Static Pressure & Ducting Check: For towers located in basements or plant rooms, we inspect the Ventilation Ducting. We ensure the fan motor has the torque to overcome the "Pressure Drop" caused by bends and grilles in the exhaust path.
Louver & Drift Eliminator Maintenance: We clean and realign the air intake louvers to ensure unobstructed flow. We also check the Drift Eliminators to ensure they aren't so clogged with scale that they are choking the fan’s ability to "breathe."
Ventilation is not a "fixed" value; it must adapt to the Malaysian climate.
VFD Modulation: We integrate Variable Frequency Drives (VFDs) to adjust fan speed based on real-time heat load. This allows the ventilation system to slow down during rain or at night, providing massive energy savings without sacrificing cooling.
Fan Pitch Adjustment: If the motor is "over-amping," we recalibrate the Fan Blade Pitch. A 1.5-degree adjustment can often fix ventilation bottlenecks while protecting the motor from burning out.

Custom Duct Design: We provide specialized sheet metal or flexible ducting solutions for cooling towers located in tight spaces or high-rise mechanical floors.
Total System Synchronization: We ensure your ventilation rates are perfectly matched with your Condenser Pump flow to maintain the optimal "Liquid-to-Gas" (L/G) ratio.
Strategic Support: Based in Kuala Lumpur, we provide turnkey ventilation audits, fan overhauls, and energy-saving retrofits for major industrial and commercial facilities.
