Different Types Of Industrial Cooling Towers For Efficient Heat Dissipation And Energy Management

Estimated read time 3 min read

Cooling towers are essential for cooling cycle water and maintaining equipment from excess heating. These cooling towers are practical in industrial facilities like oil refineries, thermal power stations, and chemical plants. These industrial cooling tower common in manufacturing facilities and numerous buildings with HVAC systems.

Cooling towers are available in various types, and choosing the correct cooling tower for your plant is important. In this guide below, you will understand some of the types of cooling towers.

Types Of Cooling Towers

The cooling tower’s design is unique because it operates different technologies to cool rotation water. Below, Cooling towers are available in numerous sizes; some are as small as a few square feet, while some are a hundred feet large. These different sizes facilitate different load configurations. These Cooling towers are also available in different shapes. The cooling industry generally categorizes cooling towers in numerous ways, including:

  • Whether their air is vertical or horizontal
  • Whether they use convection or mechanical fans
  • How and where are their fans placed

A water cooling tower system might be characterized into more than one like a counterflow cooling tower, induced draft cooling tower or a crossflow cooling tower to forced draft cooling tower. 

Crossflow Cooling Towers

The splash fill feature of crossflow cooling towers allows in-flowing air to pass horizontally over the stream of water coming from the top reservoirs. Crossflow systems are more expensive, but they are also the simplest to maintain equipment. Nevertheless, this type of cooling tower systems is frailer to frost than others cooling tower.

Counterflow Cooling Towers 

In counterflow cooling tower, the water currents downward from the tank that is situated above as the air moves vertically over the splash fill. These Counterflow systems are generally smaller in size than their crossflow counterparts. Counterflow cooling towers are more costly because more energy is required to thrust the air upward against the flowing water.

Hyperbolic Cooling Towers

Hyperbolic cooling towers are sturdy and need a minimal number of resources. Though it requires few resources, these cooling towers can efficiently maintain large-scale jobs within any big chemical factory or power plant. These hyperbolic systems utilize a chimney stacking method, enabling the outside cooler air to push the warmer damp air inside the tower. Splash fill is set around the tower’s base and sprays water over it, cooled by upward-flowing air.

Induced Draft Cooling Towers

Induced or mechanical draft cooling towers utilize mechanical pressure like a rotatable fan system which pushes air upward inside the tower. This Induced draft system applies force air with a blow-into the tower or pulls its releases through a draw-through.

Passive Draft Cooling Towers

Passive (natural) draft cooling towers work by merging the upward motion of heated air with a steep chimney to drag air throughout the tower organically. Hyperbolic towers will always be the passive draught even though these passive draught systems might feature a crossflow or counter-transport mechanism.


Suppose you have a counterflow, crossflow, natural draft, forced draft, or induced draft cooling tower available, and it will require proper cleaning to maintain it long-lasting. Maintaining your cooling tower pristine and well-maintained is necessary for keeping it up to date. Proper cleaning helps to prevent scale and corrosion, as well as it helps to control the expansion of microorganisms that may spread malfunction to the plant.
