Selection criteria for circular counterflow fiberglass cooling tower

　　Introduction: With the development of industrial production and the continuous improvement of people's living standards, it is urgent to control water pollution and develop and utilize water resources rationally.
　　
For this reason, many units commonly adopt energy-saving equipment such as fiberglass cooling towers, implement internal water closed circuits, improve reuse rates, effectively reduce costs, and at the same time, turn people's desire to adjust the temperature, humidity, cleanliness, and noise impact of the surrounding environment into reality.
　　
Fiberglass cooling tower is corrosion-resistant, high-strength, lightweight, small in size, occupies less space, beautiful and durable, and is easy to transport, install and maintain. Therefore, it is widely used in various sectors of the civil economy, especially suitable for cooling water systems such as air conditioning, refrigeration, air compression stations, and heating furnace condensation processes.
　　
Circular counter current fiberglass cooling tower
　　
The circular counterflow fiberglass cooling tower adopts counterflow gas heat exchange technology, and the packing material uses modified polyvinyl chloride waveplates to diffuse the water spraying area; By rotating the water distribution method, uniform water distribution and cooling effect can be achieved. Our factory has made partial improvements to the exterior design of this series of products, making them more reliable, durable, and easy to install
　　
main purpose
