Last year, Luoyang Gaohua provided 6 closed circuit cooling towers for Hebei coal chemical customer. Recently, our company sent engineers to the customer site for after-sales visits to understand the operation of the project. Through customer feedback and on-site adjustments, the closed cooling tower are operating well.

Closed Circuit Cooling Tower, also called Evaporative Closed Circuit Coolers.

In a closed circuit cooling tower, process fluid is circulated through coils within the unit. A water distribution system cascades water over the tubes of the coil, extracting heat from the process loop via evaporation. Air is drawn or forced across the coils, agitating the falling water and increasing the transfer of heat. A small amount of this water evaporates due to latent heat transfer through the tube and fin walls of the coil, removing heat from the system. The cooled process fluid returns to the building via the bottom coil connection. Cascaded water drains to a basin and is recirculated back over the coil.

These coolers provide energy-efficient operation in a reduced footprint compared to dry coolers, due to evaporation being used as the primary method of cooling. Because blowdown of the basin water is reduced on closed-loop systems, water conservation is also improved when compared to open-loop systems. Because evaporative coolers can oftentimes run dry when ambient conditions are favorable during reduced load conditions, water consumption is eliminated entirely during these periods of operation.

The closed circuit cooling tower manufactured by Gaohua can be used in power, metallurgy, coal chemical, petrochemical, refrigeration and other industries. If you have any interests, please feel free to contact us.
