Closed circuit cooling towers are chosen where the purity, pressure, or specific chemistry of the process coolant must be maintained.
- HVAC Systems: Cooling condenser water for chillers in buildings.
- Industrial Processes: Cooling:
- Furnaces & induction heaters
- Injection moulding machines
- Welding machines & lasers
- Power generation equipment
- Food & beverage processing lines (where contamination is unacceptable)
