Closed circuit cooling towers provide evaporative cooling for many types of systems, and the specific application will largely determine which Closed Circuit Cooling Tower is best suited for a project. Longhua's CCT series cooling towers are able to completely isolate the process cooling fluid from the atmosphere. This is accomplished by combining the heat rejection equipment with a heat exchanger in a closed circuit tower. A closed loop system protects the quality of the process fluid, reduces system maintenance, and provides operational flexibility at a slightly higher initial cost.
