Open or closed-loop cooling tower, Which is better?

cooling tower

When it comes to heat rejection cooling towers are the essential equipment for almost all type of industries. Cooling towers are a special type of heat exchangers where air and water are brought in direct contact with each other to reduce water temperature. cooling tower works on the principle of evaporative cooling. Water is broken …

Air Cooled Heat exchangers

cooling tower, Heat Transfer

Ideally, heat should not be released into the atmosphere and it should be recovered for process use. Many times process is not capable of utilizing heat and heat needs to be rejected to the atmosphere to keep the process operational. Air Cooled Heat exchangers are used to reject heat. As in the case of cooling …
