Closed-Circuit vs. Open-Circuit Cooling Towers

Choosing the Best Solution for Your Needs

A Closed-Circuit Cooling Tower is required where the cooling water quality is critical and cannot be subjected to atmospheric contamination.

Closed-Circuit Cooling Towers are selected for a very specific duty and cannot be altered later for increased duties. The coils inside these units also have the tendency to foul up over time, decreasing the efficiency of the unit and cleaning of the tubes is an enormous challenge, especially on the internal of the closed-circuit tubes.

We prefer using an Open-Circuit Cooling Tower, coupled to a Stainless-Steel Plate-Type Heat Exchanger to offer the same Closed System as with a Closed-Circuit Cooling Tower, but with the following benefits:

• Easier to clean and maintain, ensuring your heat exchange is always kept to original specification and performance is kept to the optimum.
• Additional Plates can be added in future for increased duties.
  optional self-flushing filtration system can be added to prevent clogging and fouling on the open-circuit.
• Plates that corrode can be replaced whilst on Closed-Circuit Units, the whole coil needs to be replaced if any of the tubes are compromised. This will save you a lot of money in the future.
• In addition, an optional self-flushing filtration system can be added to prevent clogging and fouling on the open-circuit.
