Cooling towers, like boilers, are used to transfer heat, by removing heat from an application and evaporating it to the atmosphere. Typical applications are "comfort cooling" in buildings such as commercial or office buildings, nursing homes, hospitals, etc. "Process cooling" applications are used in manufacturing settings and include compressor cooling and injection molding machines, among others. With Water Cooled Cooling Tower systems, there are typically three main components:
From a water treatment perspective, the most critical and challenging portion of the system to treat with cooling tower water treatment chemicals is the Open Loop. Here water is cascaded over the cooling tower, providing for greater surface area that allows for air passing through the water via the tower fan to absorb heat from the water and exhaust it out of the tower. Since water is being constantly lost by evaporation, these systems require large amounts of make-up water to remain in balance. In the Open Loop, there are four significant problem areas to be addressed with cooling tower water treatment chemicals:
Professional water treaters use a combination of tactics and cooling tower water treatment chemicals to reduce or eliminate scale deposits and corrosion caused by these impurities. And now with the advent of solid state water treatment chemicals from the EnduroSolv® line of products, facility management personnel and water treatment professionals can choose a more sustainable, safer method for treating their cooling tower water.
EnduroSolv® cooling tower water treatment chemical products are available in a full range of multifunctional solid chemical configurations, including 11 lb "bottles" 12 oz "stix", 5 lb discs and 2" diameter pucks for hard and soft water conditions, and scale and corrosion issues. These best of breed solid cooling tower water treatment chemical products are designed for use in both comfort and process cooling tower applications and include all-in-one treatments, specialty products and biocides.
