![]() | ||
Type | |||
Your choices are... | |||
Forced Draft | A forced draft cooling tower where the fan or fans are located at the bottom of the tower. Cooling air is pushed up through stack. | ||
Induced Draft | An induced draft cooling tower where the fan or fans are located on top of the tower. Cooling air is pulled up through stack. | ||
Natural Draft | Natural draft cooling towers use natural convective airflow moving up the stack to cool the water. These systems are very large, very expensive and used mostly by power utility companies. | ||
Other | Other unlisted, specialized, or proprietary cooling method. | ||

Design | |||
Your choices are... | |||
Cross Flow | Cross flow design mixes air and water at a 90-degree angle. The advantages of this design include low pressure drop and low power consumption. | ||
Counter Flow | Counter flow design mixes air and water in a vertical flow method where the water is falling and the air is rising. The advantage of this design is a smaller footprint. | ||
Closed Loop | A closed loop system works similarly to a refrigeration system. The cooling water is contained inside a closed piping system and evaporative cooling occurs by running water over the pipe containing the heated water. | ||
Open Loop | An open loop system pumps the heated water into a tank at the top of the tower. The water cascades down through a series of louvers or plates in the system while cooling air is moving upwards. The evaporative effect removes heat from the water that is then recirculated back into the process. | ||

![]() | ||
Motor Power | The rating of the motor used to drive the fan in the cooling tower. In the US it will typically be rated in Horsepower (HP) while other countries may use Watts (W). | ||
Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
![]() | |||
Cooling Capacity | The rated volume of air that is moved through the tower in a given time. It is typically rated in tons. | ||
Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
![]() | |||
Flow Rate | The flow rate of cooling water through the tower during a given time. Tower flow rates vary as a function of size or cooling capacity. | ||
Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
![]() | |||
Sump / Basin Capacity | This is the catch basin or sump where the cooled water is collected. Each system has a basin specifically designed to meet the needs of the plant. | ||
Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
![]() | |||
Operating Weight | The operating weight of the cooling tower should be used to determine where the tower should be placed. For instance, the operating weight cannot exceed the rated load of the roof it will sit on. | ||
Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
![]() | |||
Supply Voltage | The supply voltage and phase type used by the fan motor. | ||
Your choices are... | |||
DC Power | Direct current (DC) has a constant voltage and current. | ||
115 / 120 VAC | A common voltage supply for residential and commercial use. | ||
208 / 230 / 240 VAC | 230 Volts AC is a typical voltage used for smaller cooling tower fans. May be a single or three phase supply. | ||
480 VAC | 480 Volts AC is a standard plant and factory supply voltage used in North America. | ||
575 / 600 VAC | A three phase supply voltage used in the North America. | ||
International / Other | International and all other power requirements that can include 50 Hz frequency supplies. | ||

Supply Phase | |||
Your choices are... | |||
Single Phase | Single phase will typically be used with lower supply voltages like 230VAC. | ||
Three Phase | Three phase supply refers to the type of power supplied to electrical equipment where there is a 120-degree phase shift between feeder lines. | ||

Construction / Material
Back to Top
![]() |
![]() | ||
Your choices are... | |||
Fiberglass Reinforced Polyester (FRP) | Fiberglass reinforced polyester (FRP) is the material of the major body parts of the tower. This material is used in applications where there are components in the water that are highly corrosive to metal. | ||
Metal | This includes galvanized steel, stainless steel and any other metal used in the construction of the tower. | ||
Polyvinyl Chloride (PVC) | Polyvinyl chloride (PVC) is used in applications where there are corrosive materials in the water. | ||
Wood | Wood is a common building material used in cooling towers. | ||
Concrete | Concrete is used as the primary material in the natural flow cooling towers. It is used in other types as well. | ||
Polyethylene | Polyethylene is used where the cooling water has corrosive elements in it. | ||
Other | Any other type of tower body material not listed. | ||

Features & Options

![]() |
![]() | ||
Your choices are... | |||
Corrosion Resistant | Corrosion resistant materials are used in towers where the cooling water also contains corrosive chemicals and materials. | ||
Control Panel | A control is included with the cooling tower. | ||
Electric Basin Heater | In colder climates, it may be necessary to heat the catch basin to prevent freezing. | ||
Indoor Storage Tank | Indoor tanks are used instead of outdoor basins in cold climates or where temporary storage is needed. They perform the same function as a regular basin. | ||
Ladder | Ladders are used to gain access to the top of the cooling tower. | ||
Sealed Bearings | Sealed bearings extend the life of the fan bearings and motor bearings. | ||
Portable | Portable cooling towers are available in a fairly wide variety of capacities. They are trucked onto the user site and plumbed into their system. These are temporary installations why maintenance or repair is being performed on the regular site unit. | ||
Other | Any other features or options not listed. | ||
