Who we are
A factory you can audit. An engineer you can talk to.
Zhongchun designs and manufactures water treatment systems in Suzhou, China. Our engineers have commissioned more than 800 installations across 60 countries — from island desalination plants and containerised drinking water stations to pharmaceutical-grade double-pass RO.
- In-house design, fabrication, assembly and testing
- Water analysis reviewed by a process engineer, not a salesperson
- Factory acceptance test with flows, pressures and water quality report
- Spare parts and technical support for the life of the plant
Why Zhongchun
Six reasons buyers stop comparing
Most of our clients have already been quoted by three other suppliers. These are the points that decide it.
Manufacturer-direct pricing
Designed, fabricated and tested in our own 30,000 m² facility. No trading layer between you and the production line.
Designed from your water analysis
We size membranes, pumps and pre-treatment from your actual TDS, temperature and SDI — not from a template.
Documented quality
ISO 9001 / 14001 / 45001 processes, material certificates, weld records and a factory acceptance test for every unit.
Containerised and skid-mounted
Pre-piped, pre-wired and wet-tested. Site work drops to three connections and a commissioning visit.
Export experience
CE-compliant documentation, wooden-case or container packing, and Incoterms handled by people who ship weekly.
Support after the sale
Remote diagnostics, video commissioning and on-site service. Spares held for the full life of the system.
Applications
Systems built around your application
Same membrane technology, very different design logic. Choose the application closest to your project and see what we typically supply.

Before you inquire
Questions we get every week
If your question is not here, write to us — a process engineer answers, usually the same day.
Ask an engineerWhat information do you need to quote a system?
Feed water source and analysis (TDS, turbidity, SDI, temperature), required capacity in m³/h or m³/day, target product quality, site country and available power. If you do not have an analysis, tell us the source — we will specify the test.
How long is delivery?
Standard skid systems ship in 25–35 days. Containerised plants and large SWRO trains typically take 45–75 days including factory testing. We confirm the date in the contract, not verbally.
Do you install and commission overseas?
Yes. Our engineers travel for start-up and operator training, and we support remote commissioning by video when travel is not practical. Visa, insurance and travel costs are quoted separately.
Can the plant run on solar or generator power?
Yes. We design the electrical package around your supply — including solar-hybrid with battery buffer for island installations and generator-friendly soft starts.
What warranty do you offer?
24 months on the complete system, with membrane elements warranted according to the manufacturer’s conditions. Spare parts are available for at least 10 years after delivery.
Can I visit the factory before ordering?
Always welcome. We are in Suzhou, about 30 minutes from Suzhou North railway station and 90 minutes from Shanghai Hongqiao airport. We can arrange a video tour if travel is not possible.
