1. Countercurrent cooling mode is adopted, the heat dissipation blind zone is very small, and the heat exchange efficiency is high; 2. Professional water collector, control the running drift rate ≤ 0.001%; 3. High fan design to ensure that the air volume of the equipment operation meets the heat dissipation requirements; 4. Compared with other forms of cooling tower, the footprint is reduced to meet the needs of user space; 5. The box adopts closed circulation to prevent debris from entering the tower and causing spray blockage; 6. The cooler adopts antifreeze-saving and energy-saving design, which ensures that the circulating water is drained to avoid freezing when the temperature in the northern region is low; 7. Double loop cycle can be designed according to the needs of user equipment, even if one cycle fails, the other cycle can operate normally; 8. The design of the unit is beautiful and generous, automatic digital display, simple and easy to operate and maintain.
