How Does It Work?

Process circulating water from the heat source is evenly sprayed on the packing. The packing shall be designed to enlarge the contact area between the air and water flow as much as possible. The packing allows the water to form thin flow films, so that the water surface area can be exposed to the interacting flow as much as possible. At the same time, the air isdrawn in through the side air inlet, moving upward and undertaking heat transfer with spray water via the packing. Spray water becomes cool, falls into the water tank and then returns to the process circulating water for recycling. The cold air turns into hot and humid air, flows through the drift eliminator and collects the excess moisture to the water tank. It is then induced to the top of the cooling tower by the fan and is discharged into the atmosphere.

Structure & Components

1
Axial fan: Blades are made of aluminum plate. The fan features reasonable aerodynamic force, large air volume, high efficiency, low noise and corrosion resistance.
2
Tower body: It can be constructed of galvanized steel, stainless steel 304 or FRP materials.
3
Drift eliminator
4
Spray system: a key component in the cooling tower. It is designed to spray water evenly on the packing, enlarge the moisture contact area, thereby vaporizing some part of water, taking the heat away and lowering the water temperature.
5
PVC packing: Heat dissipation, heat resistance, cold resistance, flame retardant.
6
Water tank

Application

Open circuit cooling towers are widely used in cooling furnaces, induction heaters, metal parts production lines, hydraulic stations, generators and other public utilities that require a large amount of cooling water with low requirements for water quality.
