Closed Circuit Cooling Towers

Closed Circuit Cooling Tower

Introduction

Closed circuit cooling towers provide evaporative cooling for many types of systems, and the specific application will largely determine which BAC Closed Circuit Cooling Tower is best suited for a project. This isolates the process fluid from the outside air, keeping it clean and free of contamination in a closed loop and creating 2 separate fluid circuits:

  1. An external circuit, in which spray water circulates over the coil and mixes with the outside air.
  2. An internal circuit, in which the process fluid circulates inside the coil.

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 contaminate 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 (2) 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

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.

Operational Flexibility

Closed circuit towers allow for the following modes of operation not possible with open towers:
