Closed cooling tower
Water is circulated in a closed loop inside the closed (evaporative) cooling tower. (Primary cooling loop). Secondary water loop is the re-circulated spray water system.
Requirements:
- Enhanced requirements towards spray water
- Water side service is restricted only to cooling tower
Installation:
- Open area
- On top of buildings
- High-ceilinged hall
Advantages:
- No sediment
- Cleaning interval is longer
- No corrosion in primary loop
- Secondary cooling loop can be switched off
- By inserting a plate unit, fog formation can be avoided
- For higher performance, it is cheaper to connect smaller units
- Compact design
