Cellulose Pad vs. Misting Nozzles in Dry cooling Tower The choice between Cellulose Pads and Misting Nozzles fundamentally comes down to a trade-off between efficiency/maintenance and cost/footprint. Both systems serve the same primary purpose: to pre-cool the air entering a dry cooler by evaporating water,...
the reason for using a cellulose pad in a dry cooling tower is to create a highly efficient and water-conscious hybrid system. This makes the “dry cooler with cellulose pad” one of the most popular and effective designs for sustainable cooling in water-scarce regions.
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:
