Home > Product Catalogue > EWA 20 - ultra clean water production with dispenser

EWA-20-water is a demineralised water meeting the most demanding conditions for analytic purposes (18,2 MΩ/cm, minimum content of TOC etc.) Output 20 l/hr. The machines are designed for very pure water production with conductivity of 18,2 MΩ/cm and minimum content of TOC substances, and input water is reverse-osmosis-water of maximum 30 µS/cm.

Model EWA 20

  • pretreatment
    • mechanical filtration
    • ionexchange cleaning
  • special ion-exchange full cleaning
  • special UV-lamp for minimizing TOC substances below 5 ppb
  • output microbial filter
  • dispenser

The system includes following blocks:

  • precleaning by module IWA-FI, which removes mechanical impurities and partially saltiness
  • cleaning by special ORGANIT filling in IWA-OO module to a value of 18,2 MΩ/cm and minimizing TOC substances
  • decreasing the content of TOC substances below 5 ppb by using a special UV-lamp
  • output microbial filter
  • dispenser

Machine advantages

  • input water pretreatment in IWA-FI module
  • fully automatic operation
  • automatic operation in connection with water level switch in the container
