Closed Circuit Loop Water Cooling Tower Industrial Fluid Counterflow Cooling Tower Use

Closed circuit cooling towers, also known as evaporative fluid coolers, keep the system clean and contaminant-free in a closed loop. This creates two separate fluid circuits: (1) an external circuit, in which spray water circulates over the coil and mixes with the outside air, and an internal circuit, in which the process fluid to be cooled circulates inside the coil.  During operation, heat is transferred from the warm fluid in the coil to the spray water, and then to the atmosphere as a portion of the water evaporates. In addition to chiller applications and industrial process cooling, closed circuit cooling towers are often used with heat pump systems, where closed loop cooling is required.

Principle of Operation

Closed circuit cooling towers operate in a manner similar to open cooling towers, except that the heat load to be rejected is transferred from the process fluid (the fluid being cooled) to the ambient air through a heat exchange coil. The coil serves to isolate the process fluid from the outside air, keeping it clean and contaminant-free in a closed loop. This creates two separate fluid circuits: (1) an external circuit, in which spray water circulates over the coil and mixes with the outside air, and an internal circuit, in which the process fluid circulates inside the coil. During operation, heat is transferred from the internal circuit, through the coil to the spray water, and then to the atmosphere as a portion of the water evaporates.

Advantages of Closed Circuit Cooling Towers

Open cooling towers expose process cooling water to the atmosphere, typically as part of a chiller system loop.  Open towers use an efficient, simple, and economical design.  All components in an open system must be compatible with the oxygen introduced via the cooling tower.

Closed circuit cooling towers 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.

Product Details

Successful Cases

Q1: What about the lead time of cooling tower from placing a order to delivery?

A1: Standard production time is about 30days once confirmed PO. If you have any time limitation for cooling tower project, please kindly let us know when place order, we can put your order into urgently production.

Q2: Can you provide Mill Test Certificate?

A2: Yes no problem. The Mill Test Certificate , also known as Material Test Report, is a document that verifies a cooling tower’s chemical and physical properties. This can prove the cooling tower quality very well.

Q3: What kind of information request for quotation?

A3: Water flow rate, inlet and outlet temperature, dry bulb and wet bulb temperature, size limitation for water basin.

Q4:If the cooling tower can been customized for owned brand or color?

A4: Yes, available.

Q5:Can you provide OEM service for the cooling tower?

A5: Yes, we can provide OEM service for all the spare parts in the cooling tower.

Q6. How can we inspect the cooling tower parts before shipment?

A: Inspection by video or third party is available from us.
