How Cooling Towers Work and Why You Need Them

Cooling towers are a favourite feature on the landscape of many industrialised areas in South Australia. Although commonly associated with power stations and large factories, indirect dry cooling towers are present in many business properties, including office buildings and comes in different sizes from small roof-top fixing to large structures.

But why are cooling towers important to commercial properties? Well, they help maintain a manageable temperature in the work environment. Maintaining comfortable temperature is a cornerstone of employment law in Australia and therefore cooling systems ensure excess heat escapes the workplaces thereby creating a good working environment. This way, any business will find it easy to maximise productivity.

How do cooling towers work?

The cooling tower work in two ways, i.e. by evaporation or through the use of air. The latter method comprises an open circuit whereby water is pumped onto the top of the cooling tower and then redirected through an artery that turns the water into droplets. These droplets are then exposed to a passage of air that cools them. The cooled air is collected at the bottom of the structure, from where it is then passed back into the production process.

Conversely, the evaporation method exposes water to the atmosphere to let the natural process of evaporation take place. The higher the difference in temperature between the water and the outside air, the better the cooling effect. This cooling system works better in dry climates than in humid and tropical environments and can form an open or closed circuit.

Back up plans and disaster recovery cooling systems

Both cooling with evaporation and cooling with air systems depend on more than one cooling tower. Even on small business properties, indirect dry cooling towers operate in pairs with each structure being independent of the other. It ensures that in case one tower fails, the other will back it up.

In some cases, such as sudden heatwaves, a business’ existing infrastructure proves insufficient at maintaining the right working temperature. In such cases, business owners should consider renting emergency cooling towers to expand capacity and keep the working environment conducive.

It is critical for companies to have a comprehensive disaster recovery plan in place should a cooling tower fail due to technical problems or a natural event. When looking for indirect dry cooling tower services, be careful and think about the benefits they offer. Indispensable benefits include a 24/7 availability, a large capacity backup cooling towers and many years of experience in the industry.
