The Hydra High-Purity DI System is a pre-assembled cartridge system that provides deionized water using a staged filtration process. Water purification is provided using a 3-step process. Stage (1) removes particles greater than 5 micron, chlorine, and organics. Stages (2 & 3) are deionizers designed to remove dissolved minerals. The Hydra High-Purity DI series includes all cartridges and resistivity light for a total turnkey system. The Hydra high-purity DI configuration uses low odor mixed bed cartridges for applications requiring better than 10 MegOhm water quality.
