Comparison: Pad vs. Misting Nozzles Feature Cellulose Pad High-Pressure Misting Nozzles Efficiency Very High High Water Drift Very Low Can be high if not properly designed Risk of Clogging Lower (large passages) Higher (very small orifice) Coil Fouling Low risk (air is filtered by pad) Higher risk (minerals in water can deposit on coil) Maintenance...

Why Use a Cellulose Pad Specifically? (Advantages over other methods like spray nozzles) Cellulose pads (often called evaporative cooling pads) are the industry standard for this purpose due to their unique properties:

The reason for using a cellulose pad in a dry cooling tower is to create an efficient and controlled adiabatic pre-cooling system, transforming a standard dry cooler into a more powerful and efficient adiabatic hybrid cooler during hot weather. The cellulose pad is not part of the dry circuit itself; it’s an add-on component that operates...

Comparison with Other Coolers Feature Pure Dry Cooler Adiabatic Hybrid Cooler Wet Cooling Tower Water Use Zero Low (Intermittent) Very High (Continuous) Energy Use Highest (on hot days) Lower Lowest Cooling Efficiency Low (on hot days) High & Stable Highest & Stable Plume None None Visible Plume Maintenance Low Medium High

Key Components of the System This hybrid system includes all the parts of a standard dry cooler, plus the adiabatic section:
