Q: What is a cooling tower?

A cooling tower is a specialized heat exchanger, which extracts waste heat to the atmosphere through the cooling of a water stream to a lower temperature. When water comes in contact with air, it starts to reduce temperature; as a result, a small amount of water is evaporated, thereby removing the heat and humidity from the building.

Q: Why are water cooling towers better?

Evaporative heat rejection devices such as cooling towers are commonly used to provide significantly lower water temperatures than achievable with “air-cooled” or “dry” heat rejection devices. They achieve more cost-effective and energy-efficient operation of systems in need of cooling because the cooling potential of a wet surface is much better than a dry one.

Q: Why should I get a water cooling tower?

Factories, commercial buildings, and manufacturing units usually generate a tremendous amount of heat. That heat needs to be extracted so the building can be cooled down for operating efficiently. Therefore, the most cost-effective way of maintaining temperature in huge structures is by installing a cooling tower.

Q: How many types of cooling towers are there?

There are 3 types of water cooling towers:

• Cross Flow Cooling Tower
• Rectangular/Square Cooling Tower
• Round/Bottle Cooling Tower

Q: How to select the most suitable tower type for your building?

Each tower type is suitable for various buildings and operations. In the crossflow water cooling tower, air flows via the fills in the horizontal direction, and water flows down in the vertical direction. They also have splash type fillings that hold the higher suspended particles, perfect for chemical plants, big factories and processing/manufacturing plants.

Square/rectangular water cooling towers operate according to the counterflow principle. In a rectangular cooling tower, an induced draught fan is attached to the motor which pulls in air to draft it upwards leading to faster cooling of the air thus less pressure and circulation required for cooling. These types of cooling towers are perfect for light to medium industrials, pharmaceutical plants and commercial hubs.

In round water cooling towers, the airflow inside the cooling tower is uniformly distributed. The Bottle or Round cooling tower stands apart from the rest because of compact design and varying flute sizes to offer maximum heat transfer. Round water cooling towers are best suited for malls, office complexes and hospitals.

Q: How do I get my water cooling towers to run more efficiently?

Lubricating fan shaft bearings every three months and regular cleaning of the towers are required to maintain the proper functioning of the cooling system. A well-maintained and properly cleaned water cooling tower will work with original optimum efficiency, keeping energy costs low and water savings high.

Q: Why should I use SBR non-chemical water treatment for cooling towers?

The innovative SBR deploys an electrolysis reaction that breaks down and controls the elements that pollute water quality. It also enables the ongoing flow of clean quality water, using relatively little water resource and all in an eco-friendly manner. This program can reduce monthly wastewater bills for the amount of evaporated water from cooling towers that are not returned to the wastewater system.

SBR technology is a fully automatic online system that offers a myriad of benefits such as:

• The operating efficiency of your water cooling tower remains optimal.
• The cooling tower continues to operate as a new system.
• The cooling tower holds its cooling capacity.
• Save more than 50% of blowdown water.
• Allows the operation of the cooling towers at optimum 4500-5000 ?s conductivity.
• Zero chemicals mean no maintenance, storage, and discharge of chemicals.
