Frequently Asked Questions (FAQs)

What is a Cooling Tower?

A Cooling Tower is a machine used for cooling industrial hot water. It is basically a mechanical device installed within factory premises for the purpose of recycling industrial wastewater.

What is industrial water?

When water is used for industrial purposes, it is called industrial water. Water is consumed in many ways such as drinking, washing, cooking, cleaning, agriculture, and many more. Water is equally important for industries as well, where it is used for a variety of purposes like food processing, diluting, distillation, cooling, lubricating, product treatment, condensation, and crystallization, etc.

What is the use of Cooling Towers in the industry?

Water has a huge potential for heat transfer because of its high thermal capacity and low viscosity. It is a very economical fluid with numerous capabilities. Cooling is the major concern in most industries. Due to the huge water consumption in the manufacturing or processing plants, it becomes necessary to recycle it. Water coming from the machinery is pumped to the cooling tower for reusing the same after cooling. Different types of industries require different quantities of water depending on their process and capacity.

How do Cooling Towers cool water?

Cooling Tower makes use of natural processes in order to remove the heat from the water. The process of conversion of liquid into vapour is called evaporation. Cooling Tower relies on this principle of evaporation, where a small portion of water gets evaporated in the form of vapour, and the rest of the water gets cooled for reuse.

What is the mechanism of Cooling Tower?

Industrial Cooling Towers are usually a mechanical system, which utilizes the ambient air by means of an inbuilt fan. Air and water come in contact with each other within the enclosed section of the cooling tower, resulting in evaporation and then heat dissipation. Heated water enters the cooling tower via inlet pipes and is distributed over the fillings or pickings. Water drops from up to down, whereas the air travels from down to up using the counter-flow principle. The upward air carries the vapour and throws the moist air from the top. Cooled water gets collected in the water basin, which is again sent back to the industrial process.

What are the applications of Cooling Towers in the industry?

Cooling Towers are used in almost every type of manufacturing or processing industry for many kinds of machinery. Some of the industries that use cooling towers are Pharmaceutical plants, Steel Plants, Chemical plants, Sugar mills, Power plants, Plastic industry, Milk plants, Rubber plants, and many more. These industries use cooling towers for various machines and applications, such as HVAC chillers, Condensers, Heat Exchangers, Vessels, Jacket cooling, Extruders, Moulding machines, DG Sets, Turbines etc.

What types of Cooling Towers are there?

If we broadly classify the cooling towers in terms of common types, there are mainly two types of cooling towers: Natural Draft and Mechanical Draft. Natural draft cooling towers make use of surrounding air without using any mechanical force, whereas mechanical draft cooling towers are fitted with electric motors for forceful suction of the air.

Mechanical draft cooling towers are further classified into two types, in terms of air draft: Induced draft and Forced draft. Forced draft cooling towers fitted with side fans that push the air into the tower and throws the air in an upward direction. Induced draft cooling towers are fitted with the fan mounted on the top that sucks the external air and exhausts it from the top.

Cooling towers can be classified into two types in terms of design: Counter Flow and Cross Flow. Counter-flow cooling towers use the mechanism of counter contact of air and water, whereas cross-flow cooling towers use a cross-contact mechanism. In counter-flow cooling towers air moves from down to upward and water drops down from the top. In cross-flow cooling towers air travels from one side to the other side crossing the downflowing water.

Shapes of the cooling towers are also the criteria of classification. Cooling towers come in round bottle type shape, square shape, rectangular shape, cuboid shape, an octagonal shape depending on the site's requirement and manufacturers' design.

Which is the best design and type of cooling tower?

Induced Draft Counter-flow cooling tower is considered as the best cooling tower for the industry because of optimal performance, low noise level, low power consumption. Counter-flow cooling towers provide a longer contact time between air and water resulting in proper utilization of the air. The induced draft cooling airflow provides low velocity to air, making it a greater transporter of vapours.

Which is the best Cooling Tower Company?

There are several cooling tower manufacturers available in the market; however you can rely on Delta Cooling Towers Pvt. Ltd. for complete satisfaction. Owing to the presence of proficient team members, Delta offers a wide range of FRP Cooling Towers and pultruded FRP cooling towers to the industry. Delta with its superlative quality, best designing & quick service, turns out to be the leading manufacturer & supplier of quality cooling towers. Leveraging vast industry experience, Delta can provide customized solutions for all your needs of industrial cooling.

What types of Cooling Towers are manufactured by Delta Cooling Towers?

There are four series of cooling towers with Delta, namely DFC-50, DFC-60, DFC-60UX, and DPC-70. All of these cooling towers are induced draft counter flow type; however, the difference is about shape, material, and accreditation. DFC-50 series cooling towers are bottle-shaped in design, and DFC-60 series cooling towers are square or rectangular in shape. DFC-60 UX is a CTI certified series and DPC-70 is square or rectangular shape field-erected cooling towers made of pultruded FRP sections.

What are the parameters for selecting a Cooling Tower?

Cooling Tower selection is the most important thing for your industry. Proper selection of the cooling tower leads to the optimum performance of any industrial application. There are several inputs required for good selection such as entering hot water temperature, leaving cold water temperature, design wet bulb temperature, and flow rate of circulated water.
