Central Ultrapure Water System – ST-LPW32 Series combines pretreatment, reverse osmosis, EDI polishing, storage and variable-frequency loop distribution. It supplies multiple points from one monitored water plant and reduces the need for separate bench-top units.
Available production rates cover 200–2,000 L/h. The selected polishing configuration determines whether the loop supplies 15–18 MΩ·cm or 18.2 MΩ·cm water at 25°C.

MODEL DIFFERENCES
Which configuration fits the task
ST-LPW32-LI
This version raises resistivity to 18.2 MΩ·cm and lowers the TOC limit to ≤10 ppb, addressing methods requiring tighter control of both ionic and organic background.
PROCESS AND CONTROL
How this system solves the water-supply task
RO and EDI treatment
RO reduces the dissolved load before continuous EDI polishing.
Closed-loop distribution
Variable-frequency circulation keeps water moving through a multi-point building loop.
Online control and records
PLC monitoring displays water quality, flow, pressure and tank level and stores operating records.
APPLICATION ENVIRONMENTS
Where this configuration is used
Research buildings
Feeds several laboratories from a central plant with monitored distribution.
Biomedical laboratories
Provides the selected ultrapure grade for analytical and life-science preparation.
Hospital laboratory departments
Supports compatible biochemistry and instrument-water points from a shared system.
SYSTEM SELECTION
Choose the final grade and central reserve
Polishing configuration
