Cooling towers are the workhorse of water-cooled systems, with a crucial job of lowering a cooling systems water temperature. This is accomplished by bringing outside air and water inside the tower, where some water is evaporated, reducing the temperature of the residual water recirculated inside the system. A secondary function of a cooling tower is acting as an air scrubber cleaning the air brought inside the tower typically containing airborne contaminants. Airborne contaminants dust, sand, and pollen are scrubbed from the air and mixed in with the towers water supply. These contaminants get trapped inside towers water flow and cause under-deposit corrosion, biological growth, scale, fouling, and decrease overall system efficiency.

ASHRAE states that “A typical 200-ton cooling tower operating 1,000 hours may assimilate upwards of 600 lbs. of particulate matter from airborne dust and the makeup water supply.” (ASHRAE Handbook, 2020 Ch 40.16) This is an important metric when considering the number of solids that accumulate and hinder your own HVAC system.

At a recent install site of a LAKOS Basin Sweeping System a 15-year veteran operator was astonished by the improvements the LAKOS System had on their equipment. The basin had recently undergone a deep cleaning with the LAKOS System installed a few weeks after the cleaning. On startup, the basin sweepers stirred up and agitated all the sediment that collected since the deep cleaning, with the operator equating it to, “…a muddy river after a heavy rain.” After a weekend of operation with the LAKOS System, the operator could not believe how clean the water was. Stating that, “It looked better than it did when I filled it with fresh water after the deep cleaning.”

There are many advantages to adding LAKOS Filtration to your HVAC System. You can expect to reduce system maintenance, extend equipment life, maintain thermal design efficiencies, and retain valuable liquid and chemicals in your system.
