A cooling tower is a device that cools water.Water in its flow with the air for heat exchange, mass exchange, resulting in a drop in water temperature.

The closed cooling tower USES water and coils to transfer heat through the wall of the pipe to transfer the heat of the cooling medium in the coils to reach the cooling purpose.Closed cooling tower of circulating water in the cooling tower inner loop only contact with the air heat exchange cooling coil again take plate heat pipe working medium, the filling water pipe hydrating properly, compared to the open type cooling tower, the most obvious characteristics of closed cooling tower is to increase the coil, in need of cooling liquid working medium flow in the steel plate of tube is not direct contact with water, through the wall heat transfer.

Motor
Fully enclosed type, with protection grade: IP55, and insulation class: F. Smooth operation, low failure rate. Options: Siemens,ABB motor, etc.
Fan and Reducer
Adopting low speed, big chord length and width of blade fan, with characteristic of stable wind speed, low noise, few eddy current and high efficiency, etc. Enough air flow can be easily get at low rotating speed of the fan, what's more, the cooling tower fan blade angle can also be adjusted according to different climate condition, therefore, the cooling tower can not only be ensured in the rough conditions but meet the operation requirements of users.
Infill
Brand new PVC infill is vacuum formed of 0.3 thickness or more thicker PVC film with excellent chemical and high distortion resistance, big coefficient of heat transfer, small wind resistance, high ventilation performance.
We have different materials to suit different water temperature. What's more, the PVC filler's compact package design is
convenient to take out for cleaning, and the special designed configuration of the filling incorporates the function of drift
eliminator, louver and wet deck surface.
Steel Structure
Hop-dip galvanized steel framework to keep the cooling tower great performance and long lifespan, good anti-corrosion, guarantee the use of more than 15 years. Stainless steel hardware parts are also available for options if somewhere special condition needed.
Distribution System
Hot water distribution system is used F.R.P parts, non-corrosive and long life, and are specially designed for uniform
distributing and ease of inspection. A distribution cover is attached on top to prevent water from splashing out and other dirt to come into the water.
Inspection Door
Inspection doors are used to provide a convenient access to the interior for inspection, maintenance, adjustment of the internal parts, like float valve, cleaning up the lift-out strainer and flushing of the water basin.
