Principle of Operation:
Heat from the Process Fluid is circulated through the coil of the closed circuit cooler gets dissipated through the coil tubes to the water cascading downward over the tubes. Simultaneously, air is drawn from air inlet louvers from the base of the cooler and travels upward over the coil. A small portion of the water gets evaporated and the warm moist air is discharged to the atmosphere which removes the heat from the process fluid.
Functions Features:
Structure:
Frame All supporting structures are hot-dip galvanized steel to minimize rusting and corrosion ensuring long life.
Casing Made of Fiberglass Reinforced Polyester (FRP), it is lightweight, easy to assemble, no painting required and thus reducing maintenance cost.
Inspection doors are furnished to provide convenient access to the interior for inspection, maintenance, adjustment of float valve, cleaning of lift-out strainer and flushing out the sump.
Air Distribution:
Motor The fan motors are totally enclosed weather proof type. The motors are mounted on easily adjustable base located inside the fan stack ensuring lower noise level. Fan Specially designed energy efficient fans are of induced-draft axial type with adjustable pitch. Materials chosen are non corrosive of plastic, FRP or aluminium alloy. The high efficiency design ensures low running cost and the lowest possible noise level. Fan blade pitch is factory set and dynamically balanced.
Water Distribution Fills:
The fill is rigid Polyvinyl Chloride (PVC) and is honeycomb design with very large contact surface area. The fills split the air and water into several streams, increasing the time of contact and also heat transfer between water and air. The fill is in modules and is packed in the tower casing without any cutting for curves. The air pressure drop through the fill is negotiable. The fills are available with flute height of 6 mm, 12 mm, and 19 mm with sheet thickness of 1 mm and 1.2 mm.
Product Design and specifications are subject to change due to constant upgradation.
