Ultra-pure Water System (Integrated EDI)

Name: Ultra-pure Water System (Integrated EDI)
Brand: Xinnian
SKU: XN-UPW/EDI

XN-UPW/EDI

The integrated EDI system combines pre-treatment, RO, EDI stacks, a pure water tank and circulation pumps in one skid: connect power and feed water on site and production can start. Constant-pressure circulation with point-of-use return eliminates dead legs and bacterial growth, making it suitable for plants with distributed points of use and continuous demand.

Key Features

RO + EDI + storage loop fully integrated, ready to run once connected on site
Circulation and return design prevents stagnant water and keeps quality stable
On-line resistivity and flow monitoring with alarm and automatic recirculation
Optional heat sanitisation or UV sterilisation for microbiological control

Technical Data

Capacity	0.5 – 10 m³/h
Product resistivity	≥15 MΩ·cm
Tank volume	0.5 – 5 m³ (304 SS or PE)
Supply mode	VFD constant-pressure circulation
Sanitisation	UV; heat sanitisation optional
Control	PLC + touch screen, remote monitoring ready

Typical configuration shown. Systems are engineered to your feed water analysis and demand — contact us for a quotation.

Frequently asked questions

How do I choose the right capacity?

Send us raw water analysis (TDS, hardness, iron, silica), required permeate flow (m³/h) and target water quality. We size the membranes and pumps with a 10–15% design margin and return a P&ID with the quotation.

Can the system run on 380 V / 50 Hz or 440 V / 60 Hz?

Yes. Electrical design is built to your site standard — 220/380 V 50 Hz, 440 V 60 Hz or other voltages with local certification. Please state it when ordering.

Do you supply spare membranes and pre-treatment media later?

Yes, we keep membrane elements, filter cartridges and media in stock and ship spare parts within 7 days. A recommended spare parts list is issued with every system.
