Cellulose cooling pads and plastic cooling pads differ mainly in three ways: cooling efficiency, service life and upfront cost. Cellulose pads, made from treated honeycomb paper, absorb water faster and cool air by roughly 70 to 85 percent of the wet-bulb depression, making them the preferred choice for greenhouse cooling, farm ventilation and fac...
Swamp coolers and evaporative air coolers are the same core technology described with two different names. "Swamp cooler" is the informal, mostly North American term, while "evaporative air cooler" is the technical and commercial name used across manufacturing catalogs, greenhouses, and industrial ventilation projects worldwide. Both rely on water...
Cellulose honeycomb pads made from treated kraft paper deliver the strongest overall cooling performance for most greenhouse, livestock and industrial ventilation systems, reaching saturation efficiencies in the 80 to 90 percent range. Synthetic polypropylene pads trade some of that raw cooling power for longer service life and better resistance t...
An evaporative air cooler can be used in a room without a window, but only if there is another way for warm, moist air to leave the space. Evaporative cooling depends on continuous airflow: dry air enters, passes through a wet cooling pad, picks up moisture, and exits as cooled air. If that moist air has nowhere to go, humidity climbs quickly, th...
