CHVV-700
These are induced draft cooling towers for large operations . Supporting construction is hot-dip galvanized steel with fiberglass casing and with axial fan on the top of the cooling tower. Large induced draft cooling towers are installed onto reinforced concrete accumulating basin serving as foundation for cooling tower. Basic arrangement of cooling tower sections is "in line", where the number of sections is given by quantity of cooling water.
Key features:
- mounted onto reinforced concrete accumulating basin
- hot-dip galvanized steel or composite (FRP) construction with fiberglass casing
- water distribution by PVC pipes and spraying nozzles
- cooling fill and eliminators from PP or PVC
- fan unit with low speed motor and composite (FRP) blades
