Central Pure Water System – ST-LPW33 Series integrates automatic pretreatment, reverse osmosis, storage and circulating distribution. It provides one controlled source for laboratories that need different grades of centrally supplied water.
Three polishing levels cover routine RO water, analytical-grade water and enhanced low-TOC water. Production is available from 200 to 2,000 L/h.
MODELS AND DIMENSIONS
Available system models
| Model | Configuration |
|---|---|
| ST-LPW33-RO | RO water, ≤1–5 µS/cm at 25°C |
| ST-LPW33-LI | RO plus analytical polishing |
| ST-LPW33-EL | Enhanced polishing; TOC ≤20 ppb |
MODEL DIFFERENCES
Which configuration fits the task
ST-LPW33-LI
Adding analytical polishing after RO addresses tasks requiring further purification at the final supply stage, rather than RO water alone.
ST-LPW33-EL
Enhanced polishing includes a specified TOC limit of ≤20 ppb, giving an additional selection criterion where organic background matters to the method.
PROCESS AND CONTROL
How this system solves the water-supply task
Automatic pretreatment
Media, activated-carbon and softening stages protect the RO plant from suspended solids, chlorine and hardness.
Selectable polishing level
The final stage can be matched to routine washing, analytical preparation or biomedical work.
Protected loop operation
Level control, low-pressure protection, conductivity monitoring and scheduled circulation support stable unattended operation.
APPLICATION ENVIRONMENTS
Where this configuration is used
Routine laboratory services
Supplies glassware washing, sterilizer feed and general preparation.
Analytical laboratories
The selected polishing stage supports absorption, emission and spectrophotometry preparation.
Biomedical research
The enhanced configuration supports water-sensitive biomedical and chromatography tasks.
SYSTEM SELECTION
Match central polishing to each water duty
Three treatment levels
Assign routine RO, analytical and low-organic duties to the corresponding configuration before combining their demand into one central supply plan.
Connected rooms
Coordinate the outlet layout, storage and peak consumption so the selected production capacity serves the rooms that will draw water together.
