System Features
The tank will be vented with sterile air via ventilation filter.
The circulation pump feeds the water into the polishing section with circulation.
-
UV systems only: Inside the UV reactor free hydroxyl radicals (OH
) are produced. These
radicals oxidize remaining organic materials in the water.
The UPW-Pak Art.-No.: 190-0087 is filled with high grade mixed bed resins in
semiconductor quality to reduce mainly the salt content. For inorganic applications which
do not require a low level TOC the UPW-Pak Art.-No.: 190-0088 can be used.
Product water conductivity is monitored with a sensor and displayed on the system
monitor. If the conductivity exceeds a preset limit, a warning message will be displayed.
A sensor monitors the temperature of the product water. If the temperature exceeds the
limit of 40 °C, a warning message will be displayed.
The sterile filter protects the system against microbial contamination by filtration of
particles larger than 0.2 µm.
Product water will be supplied via dispenser. For a small volume of product water the
dispenser button has to be pressed slightly, for a higher volume the dispenser can be
switched into permanent position.
A check valve keeps the circulation pressure constant and prevents a backflow of the
product water.
