What are the differences between closed-circuit cooling towers and open-circuit towers!
By spraying recirculating water in a mist-like manner onto the PVC packing, heat exchange is achieved through direct contact between the water and air. Then, a fan drives airflow circulation within the tower, carrying away the hot air that has been cooled by the water—thus completing the cooling process. While this cooling method requires relatively low initial investment, it comes with higher operational costs, including water consumption and electricity usage.

In 2018, the company was awarded the "Hebei Province Industrial Design Center" and "Intellectual Property Pilot Unit".
After more than ten years of design and production experience and accumulation, continuous innovation and optimization have been made in equipment structure, cooling methods, and material processes, resulting in one existing invention patent.
Recirculating Cooling Water System
A circulating cooling water system refers to a water supply system where cooling water transfers heat, is cooled down, and then recirculated for reuse—this system includes two types: open-loop and closed-loop.
The difference between closed-circuit cooling towers and open-circuit cooling towers
An open-circuit cooling tower is a device that uses the contact between water and air to dissipate waste heat generated in industrial processes or in refrigeration and air-conditioning systems through evaporation. The basic principle is as follows: Dry (low-enthalpy) air is drawn into the cooling tower via a fan, entering from the air intake section. Simultaneously, high-temperature water molecules—rich in saturated vapor pressure—move toward the lower-pressure air. Meanwhile, warm, moist water is sprayed into the tower by the water distribution system. When water droplets come into contact with the air, heat is transferred directly through the interface between water and air. At the same time, due to the pressure difference between the water vapor surface and the surrounding air, evaporation occurs under the influence of this pressure gradient. This process removes the sensible heat from the water as it transfers heat to unsaturated dry air, while some of the water evaporates, carrying away its latent heat. Ultimately, this mechanism effectively cools the circulating water.
Characteristics and Advantages of Closed-Circuit Cooling Towers
A closed cooling tower is a heat dissipation device used to cool and reduce the temperature of circulating media. Its key feature is that the internal circulating medium is completely isolated from the outside environment, utilizing two distinct, fully separated circulation methods for effective cooling.
