Apart form manufacturing the fans for various applications, AASTHA markets the Cellulose Pad, made by various companies in India as well as abroad like Hutek Thailand, Munters Sweden/ Italy and Glacier America The Evaporative Cooling Pad, made of cellulose paper is engineered from cross-sectional, specially treated flute media capable of absorbing and retaining water to provide the maximum cooling efficiencies. The cellulose media is treated with stiffening and wetting agents to provide the cooling without any water carryover. The pads are designed for tropical and subtropical countries, ensures greatest performance during summer seasons. The Pad media is treated with anti-rot and rigidifying resins. The media is cross-corrugated to maximize the mixing of air and water. Saturation efficiency ranging from 50 to 98%, can be achieved depending upon air velocity and depth of the cooling pad. Air flows horizontally, while the re-circulating water flows vertically, through the pad. The water is collected at bottom of the pad and is re-circulated , again by a pump through the unique gutter system made of G. I. Sheet.
