CRAC tanks

Our prototype Core4 CRAC System may be the most energy efficient CRAC system deployed in the world to date but we didn’t stop there.  It’s notoriously difficult to maintain good water chemistry in cooling towers and it usually involves a combination of harsh and very expensive chemicals to control scale, corrosion, algae and bacterial growth.  Also, towers are typically running with low cycles of concentration to keep the overall TDS low (to prevent scale) so a lot of chemical laden water just ends up going down the drain as ‘blow down.’  Sean McNeil, our Water Conservation Representatives from the City of Santa Rosa’s Utility Department, not only helped us retrofit our building with dual flush toilets and ultra low flush urinals, he also turned us on to a system that promised to control all aspects of water chemistry in our cooling towers without the use of any added chemicals and without any blow down at all.

Thanks to Skasol and WCTI, we now have a ZBT system installed and expect to save more than 12,000 gallons of water a month and have eliminated all of the environmental impact associated with typical water treatment solutions.  The savings in both water and chemicals along with the rebate from the City as part of their Sustained Reduction program also made this a very cost effective solution.  Sometimes you can have your cake and eat it too.
