    Advantage of closed circuit cooling tower



    Using closed circuit cooling tower will protect the fluid from contamination, maximize system efficiency by reducing fouling and scaling tendencies, reduce system energy cost and maintenenace cost.

    Compared to other heat dissipation system:
    1.vs. cooling tower+heat exchanger
    closed circuit cooling tower is closer to wet bulb temperature and reduced fouling tendency, impove process efficiency
    2. vs. air-cooled system
    the processing temperature of closed circuit cooling tower is 10℃-20℃ lower, and closed circuit cooling tower requires less space and lower energy consumption
    3. vs. one-off water system
    reduces environmental impact, saving up to 95% of the cooling water
    4. reduced installed cost and space required

    Re: Advantage of closed circuit cooling tower

    Closed circuit can be very detrimental if the make up water is not pretreated or of sufficient quality. During evaporation, high levels of minerals and salts can build up in the sumps increasing fouling factor dramatically.
    There is no 'true' closed circuit in a cooling tower scenario due to the evaporation of the fluid.

    Locally cooling towers have been reducing in selection due to the high capital cost and high maintenance costs associated with them. The social stigma associated with cooling towers also has a poor reception with planning permissions.
