Cooling Towers

Tandem Chillers Inc. designs and manufactures cooling towers which offer a relatively inexpensive way to cool water, as long as you can use 80F to 85F (26.6 - 29.4 C) water to do your cooling. A cooling tower is any open water recirculation device that uses fans or natural draft to draw or force air to contact and cool water by evaporation. When one thinks of cooling towers, the hyperbolic towers associated with nuclear power plants probably come to mind.

Cooling Tower Drafting Techiques
Cooling towers use three main drafting techniques to draw (draft) air into the system as a coolant: forced, induced and natural draft. While forced draft cooling tower uses a fan, or collection of fans, located at the bottom of the tower to push air up through stack, the induced draft cooling tower uses fans in the top of the stack to pull air upwards. Natural draft cooling towers use natural convective airflow moving up the stack to cool the water. Natural draft systems are very large, very expensive and used mostly by power utility companies.

Cooling Tower Mixing Methods
In addition to the drafting technique , a cooling tower will use one of four methods to mix water and air to cool down the system: cross and counter flow, closed and open loop systems. The cross flow system mixes air and water at a 90-degree angle which will give you a lower pressure drop and lower power consumption. The counter flow design mixes air and water in a vertical flow method where the water is falling and the air is rising. This system uses a smaller footprint which is ideal for situations where space is limited. Like your typical refrigerator, the closed loop system uses cooled water inside a closed piping system to remove heat from the water by running the cooled water over the pipe containing the heated water. An open loop system pumps the heated water into a tank at the top of the tower. The water falls down through a series of louvers or plates in the system while cooling air is moving upwards. This process removes heat from the water which is recirculated back into the process.

Applications

Our cooling towers can be used to cool the condensers on water cooled chillers, hydraulic cooling on molding machines, blow molding machines, air compressors, or any process that can operate with 85 F (29 C) entering water.
