Introduction
ZH-RO Series (2000-3000L/H) | Stainless Steel Membrane Shell
Engineered for high-end commercial & residential use in low-hardness water areas. This cost-effective system delivers 2000-3000L/H flexible output, perfectly suiting luxury apartments, star hotels, and premium office buildings.
Food-Grade Stainless Steel Membrane Shell
Rust-proof, corrosion-resistant, and pressure-reinforced. Features superior sealing to prevent leaks & deformation. Easier to clean and more anti-fouling than standard shells, meeting elite hygiene standards.
No Scale Inhibitor + High-Precision PP Cotton
Optimized for low-hardness water. The upgraded PP cotton filters 5μm+ particles, protecting the RO membrane without chemical additives. This simplifies O&M and cuts long-term costs significantly.
97-99% Desalination Rate
Classic RO core technology efficiently removes colloids, organics, bacteria, and dissolved solids. Produces water that meets high-end direct drinking standards for luxury commercial and residential applications.
Smart Control System
Equipped with auto start-stop, low-voltage protection, flow meters, and pressure gauges. Ensures stable performance in dry, well-ventilated environments. Reliable and easy to monitor.
Cost-Effective Solution
Durable stainless steel construction combined with easy PP cotton replacement. Low accessory costs and long service life provide excellent value for high-end medium/large-scale projects.
Application
Star hotels, hot spring resorts in low-hardness water areas; providing premium direct-drinking pure water for guest rooms, catering & leisure areas, meeting high-end tourism water quality standards
High-end office buildings, business centers, Grade A office buildings; delivering high-quality direct-drinking water for corporate offices & business receptions
Large luxury apartments, healthcare communities; enabling whole-house premium water purification for drinking, washing & cooking
Feature
Made of food-grade stainless steel, it offers high pressure and corrosion resistance, sealing and anti-leakage, easy cleaning, and high hygiene, meeting premium commercial/residential standards.
Optimized for low-hardness water, it removes the anti-scaling system and upgrades high-precision PP cotton to strengthen pretreatment, efficiently intercepting particulates and protecting the membrane without scale inhibitor.
Available in 500L–3000L models, it adapts to medium/large high-end water use scenarios, runs stably, and produces water that meets premium direct drinking standards.
The stainless steel shell boosts durability and reduces replacement costs. Maintenance only requires regular replacement of standardized PP cotton and filters, cutting operational costs significantly.
