Introduction
ZH-RO Series RO Water Purifier (CE Certified)
2000/3000L/H | Scale Inhibitor-Free + PP Cotton
Engineered for low-hardness raw water areas, the CE-certified ZH-RO series is a cost-effective medium-to-large water purification system. It offers 500-3000L/H multi-spec options, fitting medium/large-scale water demands.
Upgraded precision PP cotton filtration simplifies anti-scaling while boosting pretreatment. It removes 5μm+ suspended particles and carbon powder, protecting the RO membrane and ensuring quality influent for reverse osmosis.
No scale inhibitor needed in low-hardness water — cutting operation and maintenance hassle.
Core RO tech delivers 97-99% desalination, removing dissolved solids, colloids, organics, and bacteria. Produced water meets drinking/production standards.
Intelligent features: low-voltage protection, auto start-stop. Dual pumps (raw water + high-pressure) maintain stable flow/pressure; real-time monitoring via meters, centralized control cabinet.
Stable operation in dry, well-ventilated environments. Maintenance only requires regular PP cotton/filter replacement — standardized parts, low cost.
A simple, efficient, cost-effective solution for medium/large water needs in low-hardness areas.
Application
Large office buildings, apartment buildings in low-hardness water areas; meeting demand for large-scale direct drinking pure water and daily basic water for personnel
Small food & beverage processing factories, barreled water workshops in low-hardness raw water areas; adapting to large-scale pure water production needs
Scenic spots, hot spring hotels with low-hardness water quality; providing large amounts of purified water for tourists and staff, suitable for drinking, washing and other needs
Feature
Covering four gears of water production of 500/1000/2000/3000L, it can be flexibly selected according to the actual scale of medium and large water use scenarios to meet the pure water demand of different levels.
Removing the anti-scaling system and strengthening precision filtration with PP cotton, ensuring water purification effect in low-hardness raw water environment, simplifying equipment structure and operation process, and reducing equipment procurement and use costs.
Upgraded PP cotton precision filtration component, efficiently intercepting particulate impurities, providing high-quality influent for RO membrane, reducing membrane surface pollution, extending the service life of RO membrane and lowering maintenance costs.
Equipped with low-voltage protection and automatic start-stop functions, real-time monitoring of operating status. Maintenance only requires regular replacement of standardized PP cotton and filter elements with simple operation, no need for professional technicians on duty.
