Product Features

It is an integrated system which produces pure water and UP water using tap water;

  • The controller uses international advanced 32-digit micropower processor as the core and features ultrahigh operating rate and low power consumption. The system adopts advanced EMC design, features strong interference immunity, low noise and strong surge resistance and enables reliable, stable and long-term operation of the controller;
  • The function of automatic and manual washing and circulation extends the service life of American Dow RO film imported with original packaging and reduces bacterial contamination of pure water machine;
  • Resistance constantof conductivity meter: 0.01cm-1, temperature sensitivity: ±0.1°C, automatic temperature compensation;
  • Full-intelligent control system supports multiuser, independent valuation and secondary factory and user password. System settings are protected by password to avoid unauthorized change;
  • The system functions on online diagnosis of malfunctions (quality of source water, pre-pure water and UP water), warming or auto shutdown, indication;
  • Water can be stored in both a pressure barrel and a water tank., The system can display the volume of stored water to satisfy different user needs;
  • The main power supply is 24VDC (low voltage) which conforms to the safety code. ABS engineering plastic housing and water-power separated structure adapt to humid environment, avoid damaging human body and produces ultra low radiation. The pure water pipe and joint have both passed NSF certification;
  • According to operating requirements, various terminal treaters are optional for water intake, which can effectively remove contaminants such as endotoxin, nuclease, ultratrace organics, endocrine disruptor EDS and VOC and satisfy different experimental requirements.

Product Advantages

1)The machine adopts Japanese cold cathode UV sterilizer imported with original packaging

  • 1 Alloy electrode, non-filament
  • The service life will not be affected by repeated ON/OFF
  • Longer service life (the maximum life is 50 ,000h)
  • Smaller volume (pipe diameter:Φ4.0mm, pipe length:1 50mm)
  • Dual wavelength (185nm & 254nm), thorough sterilization +degradation of TOC
  • With strong vibration strength and unique cuppy electrode, it will not be broken due to impact and can avoid damaging UV tube during transportation and disabling the machine 160*80*390mm integrated two-column purified module and 160*160* 390mm unique ultra-large- capacity four-column integrated ultra pure module. The whole column is made of edible PP. Hot melt machine enables once forming and no adhesives and impurities will be separated out. The system is internally installed with 3L+5L American Dow purified precise resin and nuclear grade resin imported with original packaging and the effluent quality reaches up to 18. 2MΩ

2)7.0 inch color capacity touch screen and animation menu

  • The system is switchable between Chinese and English interfaces and is user-friendly. It is equipped with IR remote control, one key ON/OFF, one-key pure water and UP water intake as well as one key circulation and washing. Pressure sensor system displays the pressure value of RO film in real time; air joint quick foot switch enables users to get water easily; WIFI module and mobile APP enable IOS and Android users to view online data (optional);
  • Multi- point all-line monitoring and online 3-way monitoring to monitor the quality and temperature of source water, RO water and UP water online;
  • The system can intake water qualitatively and quantitatively at fixed time. Water intake volume can be set as needed and the accuracy reaches +2ml. The quantitative range is 10-9999ml and the qualitative range is 1-1 True color display screen displays water quality, water volume and flow rate clearly.
  • The system functions on system time setting (Y/M/D/Hr/Min), timed standby (0-60min) and timed shutdown (0-24h).
  • The system collects monitored data in real time and inquires them online. With a storage life of over 1 year, it needs no computer. USB Host interface can be used to export historical alarm record and historical water intake record.
