Main Applications
Ordering Information
  • Type I ultrapure water and RO water are produced directly from tap water in one single system.
  • Electrical and water compartments are completely segregated, thus safer to operate.
  • System automatically reduces feed water pressure to within working range.
  • Pre-filtration system removes most particles, chlorine and organic compounds to protect RO membrane to extend their usable lives.
  • RO membrane removes over 99% large molecules and particles as well as 95% ions in water.
  • The automatic bypath sends the RO water to the drain if it does not meet preset quality standard.
  • The RO drain water is reused to increase the water yield. It is more environmentally friendly.
  • System automatically rinses a new RO membrane. User does not need to set special rinse program for a new RO membrane.
  • The fully automated control system contains pre-rinse, RO membrane fouling preventing flush, RO membrane and cartridge life monitoring as well as many other programs for convenient operation.
  • The pre-rinsing program starts automatically when a new RO membrane is installed so there is no need for users to set up additional cleaning procedures.
  • Two sets of dual-column purification cartridges work sequentially to ensure thorough removal of ions and organics in water.
  • Ultra purification cartridge is filled with LeFilTM and OrganeFilTM media to remove trace ions and organics.
  • Built-in 185/254 nm dual wavelength lamp reduces TOC level in ultrapure water.
  • The system recirculates automatically every hour to prevent microbial from growing
  • The system is equipped with a 30-liter PE tank (upgradable to a 60-liter) and a liquid level sensor.
  • Tank vent filter has CO2 scavenger to remove airborne contaminants, including carbon dioxide and keeps water in the tank at best quality possible.
  • The remote dispenser has a built-in high precision resistivity sensor with cell constant of 0.01 cm-1 to measure the quality of ultrapure water just prior to the dispensing point.
  • Volumetric dispensing and calibration can be easily set up on the dispenser.
  • The handle is 360 degree-rotatable and detachable from its support for effortless and instant dispensing with maximum flexibility.
  • A 0.2 μm final filter or ultrafiltration filter (optional) removes final contaminants.
  • Large LCD screens on both the water system and the POU dispenser display critical information for instant access of system operation and performance parameters.
  • With RephiBlue mobile app for remote control and diagnosis from your mobile devices (for TOC models).
  • Online TOC monitors the product water TOC level (for TOC models).
  • RephiLe can provide full document support to meet users’ GMP, GLP, FDA and other certification requirements.
