PDF Catalog
  • Large amounts of Distilled water and Ion-exchanged water can be obtained.
  • Distillation to Ion-exchange is low running cost method. Selecting Ion-exchange resin cartridge Model: CPC-N (option, A3 water level) can be much lower running cost.
  • Operation status are digitally displayed and the language can be chosen either Japanese or English.
  • Easy to replace the Ion-exchange resin cartridge.
  • Safety function: Power leakage breaker, Water leakage sensor, Water pressure reduction valve are equipped.
  • Water softener cartridge, UV lamp for sterilization is available as the optional.
