Closed Circuit Cooling Tower Manufacturers in India

Closed Loop Cooling Tower / Closed Circuit Cooling Tower operates in a manner similar to conventional cooling towers, except that the sensible heat to be rejected is transferred from the process fluid to water and ambient air directly through a heat exchange coil. The coil serves to isolate the process fluid from outside environment, keeping it clean and contamination free in a closed loop, thus creating 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.  

Why Choose Us?


Closed Loop Cooling Tower V/S Conventional System

Cooling System using a closed loop cooling tower is far simpler when compared to conventional system. The Intermediate heat exchanger, secondary pumps – piping & valves of the conventional Secondary Circuit are replaced with single closed loop cooling tower unit having inbuilt primary & secondary circuits.

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)

Closed Circuit Cooling Tower Components


Cooling Tower Packing

Cooling tower packing is one of the most important parts of a cooling tower. The packing ensures maximum contact between air and water to enable cooling.

FIL12 | FIL19 | FIL27 | FILOSS19 | ABS | FILRC

Drift Eliminators

Drift eliminators have the purpose of preventing droplets or smaller aerosols from being taken by the air flow from the cooling tower.

H130RC | RC50 | RC10 | RC20 | RC30

Motor and Fans

All parts of a cooling tower are important, but it is certainly important to exercise the necessary care of the drive gear of your cooling tower, these being the turning parts of  a cooling tower.


Water Distribution System

Engineering, production and installation of open and closed water distribution systems for your cooling tower, including the appropriate nozzles.


Air Intake Louvers

Air intake louvers prevent water splashes from the water collection tank and prevent larger debris from arriving in the water tank.
