From criminal databases to aluminum wheels to apples, three case studies detail the effectiveness of Forsta self cleaning filters in facilities with cooling towers.
Case #1: F.B.I. CJIS Division (Clarksburg, WV)
The F.B.I CJIS Division's facility in Clarksburg, West Virginia, is home to an array of services that are a lifeline to law enforcement agencies across the country. A reliably functioning cooling tower is essential to the everyday tasks carried out at CJIS.
The site engineer explained that each of the 1,000 ton cooling towers at the facility collect bugs, bird nesting materials and dirt from a nearby landfill. "Our towers do not have sumps in them that hold water. The water coming from the towers goes into the Coldwells and is then pumped throughout the system (to chillers, heat exchangers, and chemical feed panels)."
Their Forsta B2-90 model self cleaning filter is used to clean condenser water coming off of their Coldwells. It handles a flow of 150 gpm at 7 5psi and at 75˚F. The filter enters into a backwash sequence about once every three hours. The site engineer said he was pleased with the performance of their Forsta self cleaning filter. He offered that it has helped to keep the tower basins clean and he likes that the inline strainers do not need to be removed for cleaning.
He added that before entering the Forsta self cleaning filter the water had a lot of sand and dirt in it. The turbidity ran around 10 (NTU). But after the filter was installed the turbidity is around 3 (NTU).
"Yes," the engineer said unequivocally. He would recommend Forsta self cleaning filters to others with HVACR applications and added that they work better than the sand filters they have had in the past.
Case #2: Superior Industries International, Inc. (Fayettville Plant, AR)
Capital Improvement Project Manager Kyle Gunn explained, "I was handed this project and after having one of our other plants recommend Forsta, I did some research and was impressed with their track record and great product lines. Now both of our plants that use these filters have less water problems in our casting machines, meaning more production and less downtime."
Case #3: Central Washington Refrigeration, G&G Orchards Installation (Yakima, WA)
The cooling tower for this facility serves a pivotal role in the success of protecting the fruit.
Randall Gidge with Central Washington Refrigeration, who installed the unit for the orchard, explained that he manually adjusts the duration of the backwash to optimize the cleaning cycle for his unique application.
He offered that the unit he installed saves on water blow down, maintenance to the tower and chiller pans, and allowed the customer to rapidly see the difference in the water quality inside the holding tank. Gidge's plan is to utilize the M2-90 skid unit as a portable system that will be moved to service other tanks, then moved back and forth on a scheduled maintenance rotation.
In each unique HVACR application, Forsta self-cleaning filters improved cooling tower water quality by removing suspended particulate. The result in all three cases was improved facility operations, reduced maintenance, and greater reliability.
