Evaporative Cooling Pad 7090, is made of special cellulose paper and highly endosmotic water, with physical flutes having height of wave 7mm. These flutes are united each other to make an  angle of cut-off  90⁰ and they look like honeycomb structure. This special design yields larger square face in the same volume space, increases possible contact, rub and collision between air and crumpled face of the pad. Membranous water is taken shape and it covers face of the pad. When air goes through the membranous water, evaporative process into air will happen, simultaneously change temperature and humidity of the air flow. So this process is called the temperature-humidity exchange process.

The principle of the pad operation

Evaporative Cooling Pad operates under the principle of natural evaporative water. When hot and dry airflow is exhausted through wet pad, water will absorb heat of this air flow, simultaneously, water is evaporated to make temperature of the airflow to decrease and humidity of the airflow to increase suitalbly. Application of the pad to make fresh and cool air is one of the best confident and economic solutions. The self-cleaning and possible endosmosis of special cellulose papers guarantees the pad not to be decayed in water environment and maintains of the pad highly.

The temperature-humidity exchange process between water and air: Because water temperature is lower than air temperature exhausted from outside to inside workshop, evaporative water will absorb apart of heat of air and make water hotter, oppositely air becomes cooler and humidity in air increases suitalbly.

Typical applications:

– In the industry such as workshops producing garments, woolen yard, shoes, packing, mechanics, pottery and china, knitting rattan and bamboo, garage,…

– In the services such as restaurant, supermarket, public bar, amusement park,…

– In the farm such as arboretums, places growing flowers, pot plant,…

– In the livestock such as places breeding cattle and poultry,….

Pad “Black+” is developped on two basic models including Pad 7090 and Pad 7060. For this reason, aside fromspecial “Black+” protective coating, its shape, structure, standard dimension, declination of wave, angle of cut-off and saturation efficiency or pressure drop are similar to Pad 7090 or Pad 7060.

Pad “Black+” is developped specially for harsh and tough condition. It is an ideal evaporative cooling media for gas turbine inlet, textile factories, harsh water condition, locations exposed to sand storm and the application where risk of algae and bacterial growth is high. With special protective coating in Pad “Black+”, the surface will not allow algae or bacteria or mineral deposits to anchor themself.
