CyClean Centrifugal Separator

Solids removal for cooling towers - your cooling tower is a giant air washer!

The fan on a cooling tower draws in thousands of cubic feet per minute of outside air that contains sand, dust, insects, and fibers from vegetation. These airborne contaminants mix with the process cooling water and eventually these suspended particles find their way onto heat transfer surfaces. Over a period of time these surfaces become fouled and insulated causing equipment to run hotter until replacement or repair is necessary.

By removing 98% of these suspended solids mechanically, fouling is greatly reduced and chemical water treatment and bleed from the system can be reduced significantly.

Full stream filtration protects the system from dirt deposits such as winds blowing over newly plowed fields, chunks of scale eroding from steel pipe or foreign deposits encountered by adding new piping to an existing system. 

By utilizing an optional purge receptacle, expensive treated process water is not wasted in the purge cycle. A small continuous flow of dirt laden process water removed by the separator is filtered and contained in the receptacle while the clean water is returned to the cooling system. The receptacle can then be isolated for easy contaminant removal without interrupting system operation or process water flow and zero discharge to the sewer. The key to good filtration is to provide a system where the dirt laden water can enter the suction of the pump that discharges into the CyClean separator for maximum filtration of the system. If the solids can be kept in suspension, they will eventually enter the suction of the pump and then be filtered by the separator‚ before they foul your equipment. One major advantage of the Cyclean separator is that it does NOT interrupt the process. Unlike a full stream filter or strainer, there is no loss of pressure as the system gets dirty.


The CyClean Separator is a centrifugal separator specifically designed to filter cooling tower water. Dirty water enters tangent to the cylindrical casing of the separator, creating a high velocity vortex. The vortex imparts centrifugal forces on the dirty water causing suspended particles to quickly migrate to the wall of the separator. The particles become trapped in a water shear layer at the wall of the cylinder and cascade down toward the blowdown at the bottom. The debris at the bottom of the separator can be purged to drain or discharged to a bag filter.

Clean water is discharged up through the center of the separator and back into the system.
