Seattle municipal water comes primarily from the Cedar River and Tolt River watersheds, creating soft water with low mineral content compared to most US cities. This sounds beneficial, but soft water is more corrosive to metal components in cooling tower systems. The low alkalinity provides less natural buffering against pH swings, which accelerates galvanic corrosion in mixed-metal systems common in older cooling towers. Facilities near the waterfront also contend with salt-laden air that increases corrosion rates on exposed components. These factors require more aggressive corrosion inhibitor programs and more frequent cooling tower inspections than facilities in areas with harder water.
Peak HVAC Seattle has served commercial facilities throughout King County for years, giving us direct experience with how local conditions affect cooling tower performance. We work with buildings that must comply with Seattle's energy benchmarking requirements and understand how cooling system efficiency impacts your reporting obligations. Our technicians maintain continuing education in ASHRAE standards and Washington State mechanical codes. When you work with a company that knows Seattle's specific challenges, you avoid the trial-and-error approach that out-of-area contractors use while learning your water chemistry and climate patterns.
