Closed type Cooling Tower differs from an Open type in the sense that circulating water runs only inside a totally enclosed copper tube and it never contacts ambient air. Due to this fact, water quality control made simple.
■high protectability
Polluted air sucked into the tower, scale and slime generated by over-concentration and poor quality of water are attributed to be the cause of mechanical trouble.
It is not only the problem for cooling tower but also for the related equipments used in the whole system.
With Closed type cooling tower, whole cooling system is totally protected against water-related trouble.
■ reasonable total cost
* Save expense for circulating water : no refill nor replenishing of circ. water required.
* Save total maintenance & cleaning cost for entire cooling system including chiller & piping.
