Direct-Pure Genie Ultrapure & EDI Lab Water Systems


This integrated water system combines optimized sequence of water purification, delivery and monitoring technologies without compromising product water quality in a compact unit. It offers desired solutions for research professionals who work with varieties of applications utilizing Type I ultrapure and Type II pure water in the lab.

The system is manufactured in an ISO 9001 : 2015 certified manufacturing site and CE marked.

  • Type I ultrapure water and EDI (Type II) water are produced directly from tap water in one single system.
  • System incorporates advanced RO technology and EDI technology to provide Type II water at a low operation cost.
  • System automatically reduces feed water pressure to within working range.
  • Pre-filtration system removes most particles, chlorine and organic compounds to protect RO membrane and EDI module to extend their usable lives.
  • Internal RephiDuo P Pack cartridge further removes oxidants, organics, particles and scaling ions to prevent them from fouling the RO membranes and the EDI module.
  • 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.
  • Internal Ion-Pure EDI module removes the remaining ions, further reduce the content of organic compounds and has a certain capacity to prevent the growth of bacteria from RO water.
  • Ion exchange resins are continuously regenerated by an electric field. No costly resin replacement.
  • No hazardous chemical regeneration or costly resin replacement is needed.
  • EDI module has a high degree of automation and minimal electricity consumption by using the equivalent of the energy.
  • Automatic cleaning cycles and self-maintenance functions for the RO membrane increase the lifetime and efficiency of the RO membranes, EDI module as well as the final polishing cartridge.
  • Automatic hourly recirculation in the loop prevents bacteria growth and maintain water purity at all times.
  • Ultra purification cartridge is filled with LeFilTM and OrganeFilTM media to remove trace ions and organics.
  • Built-in 254 nm lamp kills bacteria and 185/254 nm dual wavelength lamp reduces TOC level in ultrapure water.
  • Flexible choices of final filters to remove specific contaminants for multiple applications.
  • Large LCD screens on both the water system and the POU dispenser display critical information for instant access of system operation and performance parameters.
  • EDI product water (Type II pure water) can be dispensed from both the water production unit and the reservoir, while ultrapure water is simply drawn at the push of a button on the handle of the water dispenser.
  • 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.
  • Standard equipped 30 L PE tank with conical bottom ensures no dead space to prevent bacteria growth.
  • Tank vent filter has CO2 scavenger to remove airborne contaminants, including carbon dioxide and keeps water in the tank at best quality possible.
  • Electrical and water compartments are completely separated, making the system safer to operate.
  • 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).
  • The system is CE/RoHS certified.
  • RephiLe provides full documents support to meet user’s GMP, GLP, FDA and other certification requirements.

* If water hardness is less than 120 ppm, RephiLe suggests using RephiTEKT RW50211KT.

If water hardness is greater than 120 ppm, RephiLe suggests using an additional water softening device to protect the RO membrane in your system.

** Product water quality may vary depending on local feed water conditions.
