Tankless Under Sink RO System
1200G High-Flow Reverse Osmosis Purifier with UV Sterilization
Tankless Under Sink RO System for Modern Kitchens
Clean drinking water has become a priority for households worldwide. Traditional RO purifiers with storage tanks take up space, require frequent cleaning, and often deliver slow water flow.
A tankless under sink RO system solves these problems by combining high-capacity reverse osmosis filtration, compact design, and real-time sterilization technology.
The 1200G tankless RO system developed by Xiamen Smart Water Technology is designed for modern kitchens and premium drinking water brands. With high-flow purification, intelligent monitoring sensors, and UV sterilization, it delivers safe drinking water instantly without bulky storage tanks.
This system is widely used by global brands seeking ODM reverse osmosis system manufacturing with international certifications and reliable quality control.
Why Tankless RO Systems Are Replacing Traditional Water Purifiers
Traditional RO systems rely on storage tanks to maintain water pressure. While functional, they come with several drawbacks:
- Bulky installation space
- Risk of secondary contamination in storage tanks
- Slow water dispensing
- Frequent pressure loss
A tankless under sink RO system eliminates the tank and purifies water instantly.
Key benefits include:
✔ Compact under-sink installation
✔ Continuous high-flow water output
✔ Reduced bacterial growth risk
✔ Smart monitoring of filtration performance
✔ Faster water production
For modern homes, restaurants, and offices, this design provides both efficiency and hygiene.
1200G High-Flow Performance
One of the biggest advantages of this system is its 1200G high-capacity membrane, which enables fast water production suitable for high-usage kitchens.
Water Output Performance
| Water Type | Flow Rate |
|---|---|
| Room temperature purified water | 3.15 L/min |
| Warm water output | 3.0 L/min |
| Boiling water output | 3.0 L/min |
This high flow ensures that multiple users can access purified water without waiting.
For families, cafés, or commercial kitchens, this means instant purified water on demand.
Advanced Two-Stage Filtration Technology
The system uses a two-stage filtration structure optimized for both filtration efficiency and filter lifespan.
Filtration Structure
| Filtration Stage | Material Composition | Function |
|---|---|---|
| Stage 1 | Pleated membrane + anti-scale coconut carbon fiber + PP | Removes sediment, chlorine, odors, and scale |
| Stage 2 | 1200G RO membrane | Removes heavy metals, bacteria, and dissolved contaminants |
The RO membrane achieves Level-1 water efficiency, improving water utilization while maintaining high purification performance.
Typical purified water pH value: 6.5 – 6.8, which is close to neutral and suitable for drinking.
Built-In UV Sterilization for Extra Safety
Even after filtration, microorganisms may grow in water pathways if systems are poorly designed.
To prevent this, the tankless under sink RO system includes terminal UV sterilization.
UV Sterilization Specifications
| Parameter | Value |
|---|---|
| UV wavelength | 270–280 nm |
| Sterilization rate | 99.9% |
| Installation location | Water outlet terminal |
This final purification step helps eliminate bacteria and viruses before the water reaches the faucet.
Intelligent Sensor Monitoring System
The system integrates four smart sensors and dual flow meters to monitor water quality and system performance in real time.
Smart Monitoring Functions
| Sensor Type | Function |
|---|---|
| Flow sensors | Measure water production volume |
| Pressure monitoring | Detect filter blockage |
| Pump frequency control | Automatically adjusts pump speed |
| Filter lifespan tracking | Calculates usage based on time + flow |
When filters become clogged, the variable frequency pump automatically adjusts performance to maintain stable output.
This smart design improves reliability and extends system life.
Filter Lifespan Management
Unlike traditional systems that rely only on time reminders, this RO system calculates filter lifespan based on both time and water usage.
| Filter | Replacement Cycle |
|---|---|
| Stage 1 filter | 6 months or 3000L |
| RO membrane | 12 months or 5000L |
This ensures filters are replaced based on actual usage, maintaining optimal water quality.
Independent Internal Water Pathways
The system uses independent internal water pipelines, designed according to strict drinking water safety standards.
Benefits include:
- Reduced cross-contamination risk
- Stable water pressure
- Long-term durability
- Compliance with international drinking water safety requirements
Air-Cooling System for Stable Operation
Instead of traditional water-cooling structures, this RO system uses air-cooling heat dissipation.
Advantages include:
- Lower maintenance requirements
- Improved system reliability
- Better heat management during high water production
This design makes the system suitable for continuous high-flow operation.
