Our Global Utilities Group focuses exclusively on condensate and related process streams.
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 demineralizer 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.
- Gravex bead resins for condensate polishing including the lowest residual chloride anion available for treating the most critical operating systems
- Uniform size Gravex for regenerable deep beds
- Less separable Gravex for non-regenerable systems
- Powdex and Ecodex for simultaneous precoat filtration and deionization
- Aegis precoatable filter septa for Powdex filter demineralizers
- AFA, the first backwashable pleated filters installed in a condensate pre-filter system
- DualGuard, combination pleated filter with a precoatable and easily backwashable surface
