Wet and Dry Closed Cooling Tower

There are three modes for Wet and dry closed cooling tower. Dry heat exchange stage: high-temperature process fluid flows in the closed coil of the Wet and dry closed cooling tower, and conducts convection heat exchange with the external air through the metal pipe wall. In this process, the Wet and dry closed cooling tower only transfers sensible heat without water evaporation. Wet heat dissipation stage: when the fluid temperature exceeds the carrying capacity of the dry section, the system of the Wet and dry closed cooling tower automatically starts the spray device to form a water film on the surface of the packing layer, and removes the latent heat through evaporation.

Composite operation mode: When the load changes, the wet and dry closed cooling tower can dynamically adjust the working ratio of the dry section and the wet section to achieve the optimal balance between energy consumption and water consumption.

Applications in industries such as power and chemical engineering offer the following advantages:
Wet and dry closed cooling towers are suitable for areas with water shortages, achieving water savings of 30%-50% compared to traditional wet towers. In winter, the dry section of the tower can be operated independently, eliminating the risk of downtime caused by spray water freezing. The packing-free design reduces airflow resistance, resulting in energy savings of 15%-20% compared to conventional cooling towers. The tower utilizes segmented anti-corrosion treatment technology, ensuring a service life of over 15 years.
