Packaged Cooling Tower Filter Systems For Cooling Towers


Everfilt's packaged CTS-Series Cooling Tower Filter Systems for cooling towers offers a practical and efficient means to reduce water treatment costs while improving cooling tower performance and reducing down time for cleaning and maintenance.


Airborne dirt, grit, sand, microorganisms plus sunlight combine to make an environment ideal for the growth of unwanted algae and slime. These contaminants find their way back into cooling loops, causing problems for pumps, valve seals, nozzles and other mechanical components.


Systems are available in single or multiple vessel packages (carbon steel or stainless steel optional), with pump mounted to the system. These are usually set up as side stream systems, filtering from 2-10% of the water circulating in the cooling loop. Filters typically will draw water from the cooling tower basin. However, other locations are feasible and may not require a pump to operate effectively.


  • Flows from 25 GPM to over 5,000 GPM

  • Factory-assembled, wired and tested

  • Skid-mounting optional

  • Automatic or Manual operation


These filters have heavy duty construction and are intended to withstand outdoor service. Filters and face piping are available either in sandblasted and coated carbon steel or stainless steel. Filter internals are all welded, 304 stainless steel assemblies. They will last the life of the filter and never crack, as happens with plastic internals.


Standard backwash controls are automatic solid state electronics in a UL listed NEMA 4 enclosure. The control unit is fully programmed and offers field adjustable settings. It includes a pump motor starter, mechanical disconnect and pressure differential switch. Backwashing is initiated either by a pre-set time interval or pressure differential override.
