Brief introduction:

A closed cooling tower (also called an evaporative air cooler, sealed cooling tower, or enclosed cooling tower) houses a tubular heat exchanger within the tower. The cooling effect is achieved through heat exchange between circulating air, spray water outside the tubes, and circulating water within the tubes. Because the circulating water circulates within the tubes in a closed loop, it ensures water quality is uncontaminated, effectively protecting the efficient operation of the main equipment and extending its service life. When the outside temperature is low, the spray water system can be shut down, saving water. With the implementation of national energy conservation and emission reduction policies and the increasing scarcity of water resources, closed cooling towers have been widely used in recent years in industries such as steel and metallurgy, power electronics, machining, and air conditioning systems.

Key features:

1.Improve production efficiency and soften water circulation without scaling, blockage, or loss.

2. Extend equipment life, ensure reliable and stable operation, reduce failures, and eliminate accidents.

3. Fully enclosed circulation eliminates impurities, evaporation, and pollution.

4. Improve plant utilization, eliminating the need for a water tank, reducing floor space, and saving space.

5. Small footprint, easy installation, movement, and layout, with a compact design.

6. Easy operation, stable operation, and a high degree of automation.

7. Reduce operating costs with automatic switching between multiple modes and intelligent control.

Technical parameters:

Cooling tower structure diagram:

Our cooling tower consists of a fan, water outlet pipe, water inlet pipe, spray pump, cooler, sump inlet grille, shell, air duct, etc. The water outlet pipe, water inlet pipe, and cooler are made of 304 stainless steel or 316 stainless steel. That is to say, the materials in contact with the circulating medium are all 304 stainless steel or 316 stainless steel. The material of the shell is magnesium-aluminum-zinc or 304 stainless steel.

Working Principle Schematic Diagram

The circulating medium circulates in a closed pipeline, and the cooling effect is ensured through the heat exchange of the air spray water flowing through the outside and the heat dissipation of the fan.

FAQ:

1. Question: What models and specifications do your cooling towers have? What is their cooling capacity?

Answer: Our company produces a wide range of cooling towers, from 6 tons-200 tons , which can meet various cooling needs.

2. Question: What material is your cooling tower made of? How durable are they?

Answer: The internal circulation of our cooling tower is made of 304 stainless steel, and the outer shell is made of magnesium-aluminum-zinc plate. These materials are well-known corrosion-resistant materials and can ensure the long-term stable operation of the cooling tower. In addition, you can also customize cooling towers made of all 304 stainless steel and 316 stainless steel to meet specific application needs.

3. Question: What kind of technical support is needed to install and maintain these cooling towers? Answer: Our cooling towers are all installed and shipped. Customers only need to connect the inlet and outlet pipes at the customer site. No maintenance is required under normal operation, but antifreeze measures are required when the weather is cold.

4. Question: How to choose your cooling tower?

Answer: Provide the following information and we will customize a plan for you.

(1)Application: What cooling tower is used for cooling, such as extruders, injection molding machines, medium and high frequency furnaces, sintering furnaces, etc., and provides the basic parameters of the required cooling equipment.

(2)Water flow: How much water needs to be circulated per hour.

(3)Inlet and outlet temperature: the temperature of the water entering the cooling tower and the required temperature of the water leaving the cooling tower.

(4)Wet bulb temperature: Provided according to the region.

(5)Voltage and frequency: It can be customized according to the industrial power consumption in different places.
