 Everfilt's cooling tower filters, sidestream filters and cooling
water filters offer a practical and efficient means of reducing maintenance and downtime of condensers, heat
exchangers and cooling towers. They also reduce costly replacements of pump casings and seals, valve seals and other process components. Contact us or call 1-800-360-8380 to speak with an engineer.
Everfilt also manufactures sand filters and multi media filters which remove
suspended solids and turbidity, while media filters typically remove other
types of contaminants present as dissolved substances.
The Importance of Cooling Tower Filters
Air borne dirt, grit, sand, and microorganisms plus water and
sunlight combine to make an environment ideal for the growth of
unwanted algae and slime which find their way back
into cooling loops, causing problems for pumps, valve seals, nozzles
and other mechanical components. These problems increase operating costs, decrease the performance of the cooling tower, and lead to more system shut downs for cleaning.
Continuous sidestream filtration causes increased overall cleanliness. Everfilt's Cooling Tower Water Filters Systems offer decreased microorganism growth far superior to that of chemical biocides.
Cooling Tower Filters are available in single or multiple vessel packages, with
pump mounted to the system. These are usually set up as sidestream
systems, filtering from 2-10% of the water circulating in the cooling
loop. Cooling Tower Filters typically will draw water from the cooling tower basin.
However, other locations are feasible and may not require a pump
to operate effectively.
Cooling Tower Filter / Cooling Water Filter Specifications
- Flows from 25 GPM to over 5,000 GPM
- Factory assembled, wired and hydro-tested
- Skid mounting optional
- Automatic or manual operation
These cooling tower 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.
