Stator Cooling Water Filtration

Generator Stator Cooling Water Filter Solutions Offered by Graver Technologies

Graver Technologies offers premium ion exchange resin water filtration solutions specifically engineered for demanding stator cooling applications. Our product portfolio addresses the unique requirements of modern power generation facilities through advanced technology.

• Gravex GC-3-1 SC (H/OH) High Purity Mixed Bed Resin: This specialized ion exchange resin features a blend of gel-type strongly acidic cation exchange resin and high-capacity gel-type strongly basic anion exchange resin, specifically formulated for stator cooler systems in a 1:1 equivalent ratio. The mixed bed resin components have a styrene-divinylbenzene matrix with sulfonic acid or quaternary ammonium functional groups. The minimum total exchange capacities achieve 1.90 meq/mL for H form cation and 1.25 meq/mL for OH form anion with 99.5% minimum whole bead integrity.

• Stratum® C Series Filter Cartridges: Graver's Stratum C Series delivers precise depth filtration for critical stator cooling systems. Featuring multi-zone melt blown construction with thermally bonded polypropylene fibers, these cartridges provide true graded pore structure from 0.5 to 100 microns with 90% removal efficiency. The molded center core withstands high temperatures and pressures, while the design ensures exceptional contaminant retention without unloading. Free of surfactants and binders, these filters offer extended service life with high void volume for optimal flow rates. Available in multiple lengths and configurations, they meet USP Class VI, FDA, and NSF 61 certifications for reliable performance in demanding power plant cooling water filtration solutions.

Key Features of Our Stator Cooling Water Filtration Solutions

At Graver Technologies, we offer advanced filtration solutions that combine the high-performance benefits of our Gravex GC-3-1 SC (H/OH) High Purity Mixed Bed Resin with the precision depth filtration of Stratum® C Series Filter Cartridges. These products are designed to ensure exceptional water purity and reliable operation in stator cooling systems for power generation. Below are the key features of our integrated ion exchange and filtration solutions:

• High Purity and Contaminant Removal: Both our Gravex GC-3-1 SC (H/OH) Resin and Stratum® C Series Cartridges ensure ultra-pure water treatment, achieving low levels of chloride, sulfate, heavy metals, and total organic carbon (TOC). This protects copper stator bar components from corrosion, scaling, and fouling, while maintaining optimal thermal transfer efficiency.

• Extended Operational Performance: The Gravex Resin features high capacity and long run times between regeneration cycles, minimizing downtime and maintenance requirements. The Stratum® C Series Cartridges complement this by providing extended on-stream life with high void volume construction, maximizing dirt-holding capacity and ensuring consistent flow rates under high-pressure conditions. These cartridges are a part of our ion exchange filter cartridges for cooling water that meet demanding operational standards.

• Superior Temperature & Pressure Resistance: Both the Gravex GC-3-1 SC Resin and Stratum® C Cartridges are engineered to perform under extreme conditions. The filter cartridges' polypropylene center cores withstand differential pressures up to 150 psid at 68°F, while the resin maintains stability throughout the operational temperature range of generator cooling systems, ensuring reliable treatment even under variable load conditions.

• Comprehensive Industry Compliance: Our solutions meet General Electric’s stringent specifications (A50A306, Rev. S-8) for stator cooling systems and comply with USP Class VI, FDA, and NSF 61 standards, ensuring compatibility with both nuclear and conventional power generation equipment. This includes the use of ion exchange resins in the power generation industry, ensuring safety and purity in high-stakes environments.

• Versatile System Configuration Options: Both the Gravex Resin and Stratum® C Cartridges offer flexibility in system integration. The resin is packaged in protective fiber drums with polyethylene lining, while the filter cartridges are available in various lengths, end cap configurations, and gasket materials to match diverse system specifications.

Industry-Wide Applications of Stator Cooling Water Filter Solutions

Our stator cooling water filtration solutions are designed to meet the needs of various sectors, including nuclear and fossil-fuel power plants. Below are some of the key industry applications:
