Closed Circuit Cooling Tower
Closed circuit cooling tower (also known as an evaporative air cooler or closed cooling tower) is the tubular heat exchanger placed in the tower, through the circulation of air, spray water and circulating water heat exchange to ensure the cooling effect.

AUVC not only provides different shapes of cooling towers used in industries, such as round shape cooling towers and square cooling towers, but also offers closed cooling towers and open circuit cooling towers as well. The type of closed circuit cooling tower is widely used in iron and steel metallurgy, power electronics, machining, air conditioning system and other industries.

How do closed circuit cooling towers work?
Closed-circuit cooling towers make it possible to separate the evaporative circuit from the process circuit (customer circuit). A stainless-steel plate heat exchanger attached to the cooling tower, in its dedicated room, allows a glycol-free operation, and a simplified and unequalled ease of maintenance.

The closed circuit cooling tower works as follows
On the process side to be cooled (customer loop), the water to be cooled enters a plate heat exchanger connected to the tower and is cooled and discharged. The primary loop is closed and never comes into contact with air.

On the secondary side of the cooling tower, the water is sucked out of the pool by a pump and circulated through a stainless steel plate heat exchanger. The water leaving the exchanger is piped to the top of the unit. This water is graded and evenly dispersed over the exchange surfaces by dispersers (also known as water distribution nozzles). Air driven by fans (axial or centrifugal) enters from the lower part of the cooling tower, is heated and saturated with water and exits from the upper part, passing between the exchange surfaces.

Under the effect of the surface tension of the filler ladder, the water spreads uniformly and flows away over the entire height of the tower. The exchange surface is thus increased.

The water cooled by forced ventilation falls freely into an inclined pool located at the bottom of the unit.

Three reasons to choose a closed cooling tower

No contamination in the primary circuit. Many civil and industrial processes require that process fluids be kept free from external environmental contamination: this is true, for example, of most food production processes. Closed-circuit cooling towers fulfil this need: in effect, the coils separate the process fluid from the ambient air drawn in by the fan, keeping it clean and contamination-free in a closed loop.

Main Usage Citric Acid is mainly used as acidulant, flavoring agent, preservative and antistaling agent in food and beverage industry.it is also used as antioxidant, plasticizer and detergent in chemical, cosmetics and cleaning industries.

Working principle:
The inlet air of KCN counter flow type cooling tower is the bottom counter flow.and the saturated warm air is formed with the falling spray water,the heat is discharged from the top air blower,then the water is recycled by the dehydrator with special structure.There is not cooling filler in the Internal space ,so there is more space to increase heat radiation area of every unit. The structure is compact, and the occupation area is small.Especially suitable for low temperature or small temperature difference between the cooling fluids.

Usage:
The counter flow closed cooling tower has the characteristics of simple structure, compact structure, small occupation area and so on.Especially suitable for low temperature or small temperature difference between the cooling fluids.Such as, medium frequency power supply, 600KW frequency furnace equipment, central air conditioning, compression type refrigerator etc..

Scope of application:
Intermediate frequency electric stove,medium frequency induction furnace,central air conditioning absorption type machine,compression absorption type refrigerator,etc.
