Square Cross Flow Open Cooling Tower

YKH Series

High-Range Cooling (Range > 18°C): Cross-flow design allows fill to be built very high without increasing airflow resistance — ideal for demanding temperature drops (e.g. 55°C down to 35°C or lower)
Deep-Cooling Industrial Processes: Fill heights of 5.5m to 15m+ enable efficient high-capacity cooling for steel processing, paper manufacturing, and rubber production
High-Temperature Wastewater Applications: Grid-type fill is easy to clean without shutting down the unit — extends applicable turbidity up to 450 ppm, preferred choice for challenging water conditions

Cross Flow Open

Cooling Capacity

50 – 800 m³/h

Model Variants

>18°C

Square Counter Flow Open Cooling Tower

YKN Series

Standard design conditions: Dry bulb 31.5°C, wet bulb 28°C, atmospheric pressure 99,400 Pa, inlet water 37°C, outlet water 32°C
Special sloped trapezoidal wave fill — excellent thermal performance, low airflow resistance, compact structure, small footprint
Wing-type hollow FRP fan blades — large diameter, low speed, low dynamic pressure — energy saving and low noise
Ultra-low noise design with noise reduction devices at air inlets/outlets and spray zone — reduces noise by 5 dB(A) vs. standard units
Flexible parallel connection — ideal for large-volume circulating cooling water systems
Fixed water distribution system with ABS multi-layer low-pressure spray nozzles — uniform distribution, long service life, low pressure head — saving pumping power
Frame options: Q-235 steel or FRP. FRP offers longer service life and lower maintenance; user selectable
For circulating water with prolonged turbidity >50 ppm or oil/grease contamination, PVC grid fill is recommended — extends applicable turbidity up to 450 ppm

Counter Flow Open

Cooling Capacity

100 – 700 m³/h
