Production of pure and laboratory water with guarantee and tradition

IWA 20 - modular assembly concept for pure water production

IWA-20-water is a demineralised water meeting the most demanding conditions for analytic purposes (18,2 MΩ/cm of minimum content TOC, etc.). Output 20-30 l/hr. The machines are designed for very pure water production with conductivity of 18,2 MΩ/cm and minimum content TOC substances, and input water is reverse-osmosis water of maximum 10 µS/cm.

Model IWA 20 io

  • pretreatment
    • mechanical filtration
    • ionexchange cleaning 
  • special ionexchange full cleaning

Model IWA 20 iol

  • pretreatment
    • mechanical filtration
    • ionexchange cleaning
  • special ionexchange full cleaning
  • special UV-lamp for minimizing TOC substances

The system contains following blocks

  • pre-cleaning by IWA-FA module, which removes mechanical impurities and partially saltiness
  • cleaning by special ORGANIT filling in IWA-OO module to a value below 18,2 MΩ/cm and eliminates TOC substances
  • decreasing the content of TOC substances below 5 ppb by using a special UV-lamp (IWA 20 model)
  • output microbial filter

Machine advantages

  • input water pretreatment in IWA-FI module
  • fully automatic operation
  • automatic operation in connection with water level switch in the container
  • function allowing the product output often achieveing the required water quality
  • periodic automatic flush, avoiding impurities and growing of microorganisms
  • alfanumeric display displaying measured, autodiagnosed parametres and other functions
  • final full cleaning of output water with the ionexchange treatment
  • simple service including module replacement


  • water for special analytic purposes
