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:

Dry cooling tower with Adiabatic fluid cooler A Dry Cooling Tower with an Adiabatic Fluid Cooler (often called an Adiabatic Hybrid Cooler) is a system that combines the water-saving benefits of a dry cooler with the high efficiency of evaporative cooling, but only when needed. It’s designed to get the “best of both...

Material Selection Factors Factor Ideal Material Trade-off Thermal Conductivity Copper > Aluminum > Steel Copper is expensive and less strong. Corrosion Resistance Stainless Steel > Copper > Aluminum > Carbon Steel Stainless Steel has lower thermal conductivity and higher cost. Mechanical Strength Steel > Stainless Steel >...
