1. The double inlet closed cooling tower is based on the design of single inlet air, and two coils and PVC heat exchange layer are added to the system of a single common fan, so that higher performance and lower energy consumption can be achieved in a small plane area; 2. The double inlet air evaporation condenser can achieve the required industrial capacity with only one module, so the double inlet composite flow closed cooling tower is ideal for large-scale projects; 3. The two-way coil can achieve the purpose of cooling different media in the same tower.
