Gopani’s Clarywound CPU is a string wound cartridge filter specifically designed for condensate per-filtration. The wound filter cartridge is made from polypropylene yarn over a stainless-steel core is engineered to remove suspended solids to ensure smooth performance of condensate polishing units in power plants. Condensate water quality is a matter of high concern in Sub-critical and Super-critical turbines. Pre-filtration using Clarywound CPU eliminates the traces of iron, copper and silica that are present in the condensate and impedes scaling & corrosion in boiler tubes, loss of boiler’s thermal efficiency and plating on turbine blades.
