In the high-rise and industrial landscape of Kuala Lumpur and Selangor, crossflow cooling towers are favored for their low-profile design and ease of maintenance. The Fill Media (or infill) is the most critical internal component, acting as the heat exchange surface where hot water from your chiller meets the ambient air. Because crossflow towers allow air to move horizontally across the falling water, the fill media must be precision-engineered to maximize contact time without causing a massive "Pressure Drop."
EKG M&E Sdn Bhd specializes in the selection, cleaning, and replacement of crossflow fill media to ensure your cooling tower maintains its design approach and energy efficiency.
In a crossflow system, water is distributed via gravity from overhead basins. As an HVAC and Clean Air Specialist, we focus on two primary fill designs used in the Klang Valley:
Hanging Film Fill: This is the "honeycomb" style made of PVC sheets. It spreads the water into a micro-thin film. Because the air moves horizontally, the fill sheets must be perfectly aligned. If the sheets warp due to UV exposure or high temperatures, "Air Bypass" occurs, and your cooling capacity drops instantly.
Integral Drift Eliminators: Many modern crossflow fill packs include "built-in" drift eliminators on the edges. This prevents "Water Carryover"—where the fan sucks treated water out of the tower—saving you money on your Air Selangor water bill and chemical refills.
Because crossflow fill is often exposed to more sunlight than counterflow designs, it is susceptible to specific M&E issues:
Calcium and Bio-Fouling: The horizontal air movement can trap city dust and smog in the fill's "chevrons." This creates a hard scale that acts as an insulator, preventing the water from cooling.
Sagging and Weight Stress: When fill becomes clogged with scale, its weight can triple. This puts immense stress on the internal support grids, eventually leading to a structural collapse of the fill into the cold water basin.
Algae Growth: Since crossflow intakes are often open to sunlight, algae can bloom rapidly on the fill face. This "bio-slime" blocks airflow and creates a breeding ground for Legionella.
We provide a turnkey solution for fill maintenance that protects your Chiller’s head pressure:
Precision Chemical Descaling: For lightly fouled towers, we use inhibited acidic cleaners to dissolve calcium without damaging the PVC.
Full Pack Replacement: If the fill is brittle or heavily clogged, we perform a total replacement. We use UV-resistant, fire-retardant PVC packs that are custom-cut to fit your specific tower dimensions (e.g., Marley, BAC, or Evapco models).
VFD & Airflow Calibration: After a fill replacement, the "Static Pressure" of the tower changes. We recalibrate your Variable Frequency Drive (VFD) and Fan Pitch to ensure the motor is pulling the exact volume of air required for the new, clean media.
| Feature | Clogged/Warped Fill | EKG M&E Refurbished Fill |
| Heat Rejection | Reduced (Low Surface Area). | Maximum (Optimized Film Contact). |
| Airflow Path | Turbulent / High Resistance. | Laminar / Low Static Pressure. |
| Chiller Load | High (Inefficient). | Low (Reduced kW per Ton). |
| Water Distribution | Uneven (Channeling). | 100% Uniform Wetting. |
Site-Specific Selection: We help you choose between "High-Efficiency" film fill for clean water or "Clog-Resistant" splash fill for industrial applications.
Structural Inspection: While the fill is out, we inspect the Gravity Distribution Basins and Hot Water Orifices to ensure the water flow is perfectly balanced.
Strategic Support: Based in Kuala Lumpur, we provide turnkey fill replacements, Dynamic Balancing, and 24/7 emergency repairs for commercial and industrial plants.
