A cooling tower is a heat exchanger that specializes in the air and water are brought into direct contact with each other in order to reduce the water temperature. As this occurs, a small volume of water evaporates; reducing the temperature of the water is circulated through the tower. Water that has been heated by an industrial process or air conditioning condenser is pumped to the cooling tower through pipes. The water flowing through nozzles spraying water on the material called "filler" which slows the flow of water through the cooling tower and the water surface exposed as much as possible for maximum air contact - water. As the water falls downward through the cooling tower, which is exposed to the air being drawn through the tower by the electric motor driven fan. When water and air meet, a small amount of water evaporates, creating a cooling action. The cooled water is pumped back to the condenser or process equipment where it is reheated. Then pumped back to the cooling tower to be cooled again. Fundamentals of cooling tower provide a basic knowledge cooling tower and are a great resource for those wanting to learn more.

TYPES OF COOLING TOWERS Cooling towers are designed and manufactured in various types, with many sizes available. Not all towers are suitable for all applications. Understanding the different types and their advantages and limitations, it is important to determine the tower on the right for a project. The list of products offers an overview of the towers to help determine which one is right for your application. Torres factory installed (PAF) Factory assembled towers virtually undergo complete assembly at its point of manufacture, which are sent to the site in so few sections as the transport mode allows. A relatively small tower send essentially intact. A, the cooling tower largest multi-cell modules are mounted as factory and shipped with appropriate hardware for mounting by the user. Torres factory installed towers are also known as "FAP" "packaged" or. Factory assembled cooling towers can be cross flow or counter flow induced draft or forced draft, depending on the application. While all applications are different, the Marley NC cross flow induced draft tower is widely used for HVAC and light industrial applications. Countryside - erected cooling towers (FEP) Field towers - erected mainly constructed on the site of end use. All large cooling towers and many of the smaller towers are prefabricated marked piece and sent to the site for final assembly. The manufacturer usually provides labor and supervision for final assembly. Field - towers can be erected cross flow or counter flow, depending on the application. For energy and industrial applications, the F400 Marley counter flow tower can be customized to meet your exact specifications for the operation, structure, drift and reduced plume. Cooling towers cross flow In cross flow towers water flows vertically through the filling whereas the air flows horizontally through the flow of falling water. Because of this, the air does not have to pass through the distribution system, which allows the use of flow distribution basins gravity hot water mounted on top of the unit above the filling. These basins are applied universally in all cross flow towers. Counter flow Cooling Towers Counter flow towers are designed so that air flows vertically upward against the stream of water falling into the filling. Because of this vertical air flow, cannot use, watersheds open gravity flow typical cross-flow designs. Instead counter flow towers spray systems use pressurized tube type for spraying water on the top of the filling. Since the air must be able to pass through the spray system, the pipes and nozzles must be much further apart so as not to restrict the airflow. Induced draft vs. forced draft Cooling towers are induced draft fans are typically mounted on top of the unit and pull air through the fill media. By contrast, the air is pushed by blowers located at the base of the air inlet face of forced draft towers. PERFORMANCE DRIVERS Optimally designed system - Using a system-wide approach each unit and the component is designed and developed to work together as an integrated system for efficient performance and long life. Cooling HVAC Free - A free cooling system allows the tower to directly meet the cooling requirements of a building without the need to operate the refrigerator in a cold climate. The goal of a free cooling system is to save energy. There are certain types of free-cooling systems and certain elements that must be in place for a free cooling system is considered. Variable Flow - There may be significant opportunities for energy savings if the cooling tower can be operated under variable flow in low activity. Variable flow is one way to maximize the effectiveness of the tower capacity installed by any process flow has. OEM Parts - precisely engineered to deliver a reliable, Marley OEM parts are built to the highest standards and tighter tolerances for long life. Geareducer Solutions - gear boxes are available in a variety of designs and gear ratios to accommodate different fan speeds and horsepower of the cooling towers. The Marley Geareducer Solutions program allows customers to order a new replacement gearbox for tower SPX or factory-trained technician can repair an existing gearbox or a gearbox rebuild with OEM parts Marley. Full - One of the only major components of cooling tower fill. Their ability to promote both maximum contact and maximum contact time between the air and the water determines the efficiency of the cooling tower. The two basic classifications of splash type fill are filled (water breaks) and film type fills ( extends the water in a thin film ) . Drift eliminators - Designed to remove water droplets discharged air, droplet separators, causing the air and drops to make sudden changes of direction. This causes water droplets to be separated from the air and deposited back into the tower. Nozzles - Crossflow configuration allows the use of a distribution system by gravity flow with a nozzle as Marley ST. With this system, the supply water is raised to the water distribution basins above the filling hot and then flows over the filling (by gravity) through nozzles in the bottom of the distribution basin. Counter flow configuration requires the use of a type of closed tubing pressure and the spray nozzles as Marley NS. Fans - Cooling tower fans must move large volumes of air efficiently and with minimal vibration. Manufacturing materials must not only be compatible with the design but also must be able to withstand the corrosive effects of the environment that is required to operate the fans. Ultra Quiet Marley fan is an example of a fan that can be used in situations where the sound is too low a necessity. Axles - The drive shaft transmits power from the engine output shaft to the input shaft of the gearbox. Because the shaft operates within the tower, which must be highly resistant to corrosion. As for the full engine speed, should be well balanced and able to be re - balanced. Due to the requirements of the rigorous cooling tower the Comp - DS shaft Marley carbon fiber was designed.
