Laboratory Ultra-pure water Water Purification System 
UPW-N Series

Functions:
Built-in pretreatment column
Contains activated carbon filter, could effectively remove free active chlorine from source water;
Contains PP cotton filter, could effectively remove impurities such as solid particles and protect the RO membrane from blocked;
Built-in pretreatment column, save spaces, it is more convenient to use.
 
High performance of reverse osmosis membrane
To meet different needs, there is a variety of membrane forms can be selected, such as single membrane, double membrane, two-stage reverse osmosis membrane etc, ;
Using high-performance Dow reverse osmosis membrane, which can effectively remove inorganic ions, bacteria, and solid particles, long service life.
 
Purification column / Ultrapure column
Double column design, large volume of resin filling, long service life;
Purification column adopts high quality precision resin, high exchange efficiency and stable water quality.
Ultrapure column adopts nuclear grade polishing resin, higher exchange efficiency, preparation of 18.2 M Ω. cm ultrapure water.
 
High power single/double wave UV lamp
Single wave UV lamp (254 nm), kills bacteria and other microorganisms, improving the water quality while preventing microbes breeding.
Double wave UV lamp (185 nm and 254 nm), kills bacteria and other microorganisms while effectively degrading organic matter and reducing the TOC content.
 
Conductivity sensor
Equipped with three sets of conductivity sensors, containing one set of special conductivity sensor (with temperature compensation function and the electrode constant is 0.01) for pure water system, comprehensive monitoring the operation of the pure water system and water quality change.
 
Built-in pressure tank
Reduce the laboratory space usage while improving the system efficiency of water purification system .
 
Front filter
0.22 um membrane filter, remove remaining trace impurities in source water and removal process, further improve water quality.
 
Leakage protection
With leakage detection sensor, under emergency situations, it can automatic alarm and adjust the instrument into standby mode.
