A cooling tower is a heat rejection device, which extracts waste heat to the atmosphere though the cooling of a water stream to a lower temperature. The type of heat rejection in a cooling tower is termed "evaporative" in that it allows a small portion of the water being cooled to evaporate into a moving air stream to provide significant cooling to the rest of that water stream. The heat from the water stream transferred to the air stream raises the air's temperature and its relative humidity to 100%, and this air is discharged to the atmosphere. 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, like the radiator in a car, thereby achieving more cost-effective and energy efficient operation of systems in need of cooling. Think of the times you've seen something hot be rapidly cooled by putting water on it, which evaporates, cooling rapidly, such as an overheated car radiator. The cooling potential of a wet surface is much better than a dry one.

Common applications for cooling towers are providing cooled water for air-conditioning, manufacturing and electric power generation. The smallest cooling towers are designed to handle water streams of only a few gallons of water per minute supplied in small pipes like those might see in a residence, while the largest cool hundreds of thousands of gallons per minute supplied in pipes as much as 15 feet (about 5 meters) in diameter on a large power plant.

The generic term "cooling tower" is used to describe both direct (open circuit) and indirect (closed circuit) heat rejection equipment. While most think of a "cooling tower" as an open direct contact heat rejection device, the indirect cooling tower, sometimes referred to as a "closed circuit cooling tower" is nonetheless also a cooling tower.

National Cooling Tower have in-house expertise to provide a consultancy service related to all issues in respect of water cooling towers and their application.

National Cooling Tower have in-house expertise to provide a consultancy service related to all issues in respect of water cooling towers and their application.

We will review the process demands and as dictated by client requirements conduct a detail design study to optimize the performance of a cooling tower to meet both system and environmental requirements. This may require special considerations be taken to limit noise level, plume control and / or achieve required energy conservation measures.

We are able to provided assistance from conception to project completion and ongoing maintenance. Our degree of involvement can be as little or as much as client desires.

We will establish the cooling demands, write a comprehensive technical specification and scheme for an enquiry, provide an unbiased independent appraisal of tenders, if required we can maintain QC /QA of the supply, act as clients engineer during designing, construction, commissioning or erection and after sales maintenance etc.

This will results your manufacturing process execution smoothly years after years.
