Closed circuit Cooling Towers are hybrids that pass the working fluids through a tube bundle, upon which clean water is sprayed and a fan-induced draught applied. The warm water is cooled to a temperature lower than ambient air dry-bulb temperature, if the air is relatively dry. Evaporation results in saturated air conditions, lowering the temperature of water in the tower to a value close to wet bulb air temperature, which is lower than the ambient dry bulb air temperature, the difference determined by the humidity of the ambient air.


Structure & Components of FRP Square Cooling Tower:

Coil Bank

In closed circuit cooling tower 99.9% pure copper coils are hailed to be the most efficient cooling coils for counter flow closed circuit cooling towers.

Galvanised Coil Bank

The performance / life optimised galvanised coils are preferred coil banks for huge closed circuit cooling towers. Made from carbon steel pipes, the whole unit is hot dip galvanised after fabrication.

Induced Draught Fans

The induced draught fans are driven by totally enclosed surface cooled motors. Fan is made from Industrial Polymer / die cast aluminium or carbon fibre for noise free performance.

Control Panel

Control Panel incorporates all the controls / switchgear for starting stopping the water spay pumps and induced draught fan. Digital display indicates temperature of the incoming hot water and outgoing cold water.

Spray Pump

A low head pump is used for carrying the cooling water from the sump to the top of the cooling coil to be sprayed on the coil bank.

Drift Eliminator

TClosely Pack Z bars prevent the entrainment of the circulating water from the cooling tower.

Features & applications of Closed Circuit Cooling Tower

Salient features:

We are specialized in manufacturing precision engineered FRP cooling towers that offer the following features:

  • 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.
  • Hot Dipped galvanized cooling tubes to avoid corrosion and maximum heat exchange with the cooling medium. For better conduction of heat we also provide copper tubes instead of GI.

Applications:

  • Chemical Industries
  • Pharmaceutical Plants
  • Induction Furnaces
  • Chilling Units
