Cooling Tower

Cooling Tower

Cooling tower is a device used to lower down the temperature of circulating water in HVAC and process application. Hot circulating water comes in contact of relatively cold ambient air and discharge the heat to the air by means of evaporative cooling.

Cooling Tower Classification:

1. On the basis of Heat Transfer

A. Evaporative
The extensive name for cooling tower is open evaporative cooling tower. Cooling towers are able to draw off heat from a process or a cooling circle in an efficient way. In a cooling tower, water is put in direct contact with surrounding air. A small part of the cooling water, i.e. 1-2%, evaporates. This evaporation causes an increase in temperature and humidity of the air and a decrease of the temperature of the water. By using the evaporation, it is possible to cool below the normal air temperature. The minimal realizable temperature is the wet bulb temperature.

B. Closed Air Cooling or Closed Circuit Cooling:
In closed circuit cooling tower primary fluid passes through the coils and the secondary media extract the heat by the heat exchanger.

2. On the basis of Direction of Flow of Air & Water

Counter Flow & Cross Flow Cooling Tower
Counter means that the water flows down while the air is pulled upwards by a fan. As the water flows further through the system, the air it encoun¬ters is fresher, in other words cooler and less saturated with moisture. Counter flow cooling towers can approach the wet bulb tem¬pera¬ture better compared with cross flow cooling towers. Using the cross flow principle, warm water flowing down through a cooling unit is cooled by air drawn upwards by a fan. Evapo¬ration and direct heat exchange cause a rapid drop in tem¬pera¬ture. Compared to counter flow cooling towers, induced-draught cross flow cooling towers are much quieter and smaller. The perfor¬mance figures are next to perfect.

3. On the basis of exhausting air:

Induced Draught & Forced Draught Cooling Tower:
Fans cause a continuous air draught. When the fan is blowing, the apparatus is on overpressure, which is called forced draught. In contrast, when the fan is sucking, we have under pressure, which is called induced draught. For cooling towers with a forced draught, 2 types of fans are possible: axial (plate with blades) or radial fans (snail-shell)

APPLICATIONS OF COOLING TOWERS

1.Industrial sector: Thermal Power Plants, Chemical Plant, Sugar Plants and Process Plants etc.

2.Commercial Sector: Malls, Buildings, Schools, Hotels & Hospitals etc.

GEA POLACEL COOLING TOWERS:

GEA Polacel designs, manufactures and installs a complete range of cooling towers based on cross flow and counter flow. GEA Polacel is synony¬mous with quality and innova¬tion in this area. They have been building cor¬rosion free cooling towers since 1967, and are still in the lead when it comes to effi¬ciency and noise reduc¬tion.

The GEA Polacel cooling towers stands for long lifetimes and minimal maintenance needs. We have build cooling towers that after 35 years are still function perfectly. This is achieved through the materials used stainless steel combined with glass fiber reinforced polyester and the experience of our engineers. The result is a cooling tower that is low maintenance, energy efficient and able to supply constant excellent problem free performance.
