CLOSED CIRCUIT COOLING TOWER MANUFACTURES IN INDIA

Closed Circuit Cooling Tower / Closed Loop Cooling Tower operates during a manner the same as standard cooling towers, except that the smart heat to be rejected is transferred from the method fluid to water and close air directly through a heat exchange coil. The coil serves to isolate the method fluid from outside atmosphere, keeping it clean and contamination free during a control system, so making two separate circuits.

  • Primary / Internal circuit in which the process fluid circulates inside the coil
  • Secondary / External circuit sprays circulating water from the basin over the coil which evaporates to reject heat to the environment.  

Closed Loop Cooling Tower V/S Conventional System

Cooling System employing a control system cooling is way easier in comparison to traditional system. The Intermediate device, secondary pumps - piping & valves of the traditional Secondary Circuit ar replaced with single control system cooling unit having inherent primary & secondary circuits.

Operating Principle

closed-circuit-operating-principle
  • This process fluid is circulated through the coil of the closed loop cooling tower.
  • Heat from the process fluid is rejected through the coil tubes.
  • Part of the heat is removed directly by the downward induced air and discharged to the surrounding.
  • Rest of the heat is rejected to the water cascading down over the tubes.
  • Simultaneously air is drawn in through the air inlet louvers at the base of the closed loop cooing tower.
  • A small portion of the water is evaporated which removes the heat. The warm saturated air travels through the drift eliminator & discharged by the fan to the surrounding thereby reducing drift water loss.
  • The remaining cooled water is collected in the basin at the bottom of the closed loop cooling tower. Spray pump connected to the basin pumps the water to be sprayed onto the coil.

Advantages of Closed Circuit Cooling Tower

Closed circuit cooling tower is used in the following applications: water source heat pumps, industrial processes, air compressors, weld machine cooling, mould water cooling, power plant auxiliary cooling, furnace cooling, transformer cooling, closed condenser loops, critical systems, and systems requiring plume elimination.

Clean process fluids sustain the performnace of high efficiency components. Save on energy consumption by operating in “Free Cooling Mode” during the winter

Reduces or eliminates cleaning the heat exchanger. Extends the life of the equipment

Free Cooling without an intermediate heat exchanger. Dry operation during winter months. Variable speed pumping to conserve energy without the potential of scaling the unit.

Lower volume of recirculation water reduce water treatment cost. Dry operation and adiabatic modes reduce or eliminate water consumption.

Compact single piece of equipment conserves space replaces three components (cooling tower, heat exchanger, and pump arrangement)

Features of Closed Cooling Towers

  • Uniform water distribution system with large orifice nozzle to reduce clogging.
  • Specially designed axial air-foil fan blades for low noise levels and lower power consumption. Moving parts are placed in such a way that they can be easily removed and repaired.
  • Highly efficient sprinkling pump to ensure low power consumption and low noise.
  • We have a wide base working platform to ease the tedious maintenance process.
  • We have a water level control system that controls that maintains a constant level of water in the Cooling tower basin.
