Advantages of Closed-Circuit Cooling Tower
- Keeps the Process Fluid Clean: Since the primary loop is sealed, there is no exposure to airborne contaminants (dust, dirt, microbes, gases). This prevents fouling, scaling, and corrosion inside the process system.
- Operational Efficiency: The process loop stays clean, maintaining high heat transfer efficiency for longer periods. There’s no loss of process fluid to evaporation.
- Easier Maintenance: Maintenance is focused on the evaporative loop, which uses less critical water. The expensive process fluid and the sensitive equipment it flows through are protected.
- Environmental & Chemical Use: Chemical water treatment is only needed for the evaporative loop, which typically uses standard tap water. This means less chemical usage overall and no treatment of expensive process fluids.
