How to Choose the Right Water Purification System
Matching a purification system to your workflow comes down to the water grade your applications demand, the feed water you have available, and the space and power at the install site. Review these axes before specifying a unit.
- Feed water requirement: verify your source meets the < 20 µS/cm inlet specification before installation.
- Voltage and power: this unit runs on 220V/50 Hz — confirm site electrical service supports it.
- Footprint: at 21.6" × 14.7" × 14.4" and 42.1 lbs, plan bench or wall clearance accordingly.
