Condensate Polishing Solutions
For power plants using condensate polishing units, Graver’s filtration products—including ion exchange filters and condensate demineralizer support media—deliver reliable performance for high-purity boiler water treatment.
Condensate polishing is a critical water purification process used in power generation and industrial settings to remove impurities from steam condensate before it is returned to boilers or steam generators. Its primary purpose is to protect equipment such as boilers, turbines, and reactors from corrosion and scale buildup, ensuring operational efficiency and longevity. Using ion exchange condensate polishers and advanced filtration systems, this process maintains high water purity, which is crucial for preventing damage in high-pressure systems. In industries like nuclear, fossil power, and combined cycle plants, condensate polishing enhances system reliability. At Graver Technologies, we offer reliable and durable condensate polisher resin and filtration solutions, including Gravex® and Aegis® products,designed to deliver high-purity condensate water polishing for Industrial applications.

Engineered Water Treatment Solutions to Meet the High Demands in the Utility Industry
Electric generating station condensate must be maintained at a very high purity level to protect boilers, steam generators, reactors, and turbines from corrosion. To remove contaminants from the condensate, deep bed ion exchange condensate polishers are used and sometimes preceded by a Powdex® filter demineralized or a fine particulate filtration system. A Powdex system can also stand alone as the primary polisher. Graver Technologies is the most experienced and knowledgeable Ion Exchange product and Filter Septum manufacturer and offers the most complete range of products to meet today’s challenges. Whether the need is for high purity Gravex® condensate polishing ion exchange resins; the original Aegis® wound, DualGuard® or AFA® pleated filter septa; or the Powdex & Ecodex® families of premium resins, the original and most widely used powdered ion exchange resins, Graver Technologies has the answer for your application.
