Energy Saving Closed Cooling Tower Counter Flow Metal Construction

Our closed cooling tower (also known as evaporative air cooler, sealed cooling tower, or enclosed cooling tower) features a tubular heat exchanger within the tower structure. The cooling effect is achieved through efficient heat exchange between circulating air, spray water outside the tubes, and circulating water within the tubes.

The closed-loop design ensures water quality remains uncontaminated, protecting your main equipment and extending its service life. During colder temperatures, the spray water system can be deactivated to conserve water. With increasing focus on energy conservation and water resource management, our closed cooling towers are widely used in steel/metallurgy, power electronics, machining, and HVAC systems.

• Enhances production efficiency with softened water circulation that prevents scaling, blockage, and water loss
• Extends equipment lifespan through reliable, stable operation with reduced failures and accidents
• Fully enclosed circulation eliminates impurities, evaporation, and contamination
• Optimizes plant space utilization by eliminating the need for water tanks
• Compact footprint for easy installation, relocation, and flexible layout
• Simple operation with stable performance and high automation level
• Reduces operating costs through automatic mode switching and intelligent control

Our cooling tower consists of:

• Fan
• Water outlet pipe
• Water inlet pipe
• Spray pump
• Cooler
• Sump inlet grille
• Shell
• Air duct

All components in contact with circulating medium (water outlet pipe, water inlet pipe, cooler) are constructed from 304 or 316 stainless steel. The shell is made of magnesium-aluminum-zinc or 304 stainless steel.

The circulating medium flows through a closed pipeline system, with cooling achieved through heat exchange between air spray water flowing externally and efficient heat dissipation via the fan system.
