Graver Technologies’ specialty mixed bed resin, Gravex GC-3-1 SC

Stator cooling water is one of the most critical systems in a power generating plant. The copper stator bars are cooled in this closed loop system to prevent overheating and reduced generator performance.

A mixed bed ion exchange polisher continuously treats the recycling water to remove ionic contaminants while providing some filtration of particulates, generally copper oxides.Graver Technologies has the optimum mixed bed product, Gravex GC-3-1 SC, for your stator cooling system.
