Product Features
1. Equipped with power indicator, pump operation indicator, low-pressure indicator, and system flushing indicator functions.
2. Uses imported ion filtration membranes and high-pressure, silent pure water pumps for more reliable operation and broader water quality applicability.
3. Features a system flushing function: before each startup for water production, the system automatically flushes for 18 seconds before starting water production.
4. Equipped with a system protection function: the device automatically shuts down when water pressure is too low or there is no water, and automatically starts up when water supply resumes.
5. High output, low energy consumption, and power savings: water output of 20L/h, power consumption of only 25W, which is 1/300 of similar products.
6. Uses advanced water treatment technology, with a high-purity water output ratio of about 40% and low water consumption.
7. No electric heating tube required, no scaling issues, and no need for cleaning.
8. No heat loss, room-temperature output water requires no cooling and can be directly used for experiments.
9. Simple operation, easy maintenance, and low operating costs.
10. Equipped with a two-stage RO pre-desalination system (optional for high salinity water quality).
11. Capable of water quality and output upgrades.
12. The RS-I series, in addition to the features and functions of the RS series high-purity water machines, also includes water quality monitoring, allowing real-time monitoring of output water conductivity and temperature.
Why Use a High-Purity Water Machine
· Stable water quality output, simple testing methods, no need for repeated experiments.
· High water output, with base models at 10L/H or 20L/H, and up to 100L/H maximum.
· Output water at room temperature, requires no cooling, can be used directly, reducing experimental analysis time and avoiding secondary contamination during cooling.
· Water production on demand, avoiding time wasted during transportation and speeding up analytical experiment efficiency.
· Most importantly, the instrument operates at only 25 watts, compared to electric thermal water distillers which typically consume 7-8 kW, commonly 10 kW, or even 15 kW, making it more energy-efficient and reducing daily operating costs.
· For more comparisons with traditional electric thermal water distillers, see the next section.
Comparison Advantages Over Traditional Electric Thermal Water Distillers
Power Consumption High energy consumption: 380V/7500W, 15000W Low energy consumption: 220V/25W, 50W
Water Purity 5 μS/cm   (25°C) 0.2 μS/cm  (25°C)
Water Standard   (GB6682-2008) Laboratory Grade 3 Water Better than Laboratory Grade 2 Water
Wastewater Ratio 1:20 (1 is water output) Single distillation, more for double-distilled water 1:4 (1 is water output)
Water Stability Low and unstable water purity output High and stable water purity output
Operability Inconvenient operation, requires dedicated personnel Simple operation, no need for dedicated personnel
Safety Risks of dry burning, tube explosion, etc. No electric heating tube, no scaling issues, high safety

Main Uses of High-Purity Water:
1. Final rinsing of laboratory glassware.
2. Water for preparing buffers and chemical reagents.
3. Water for preparing microbiological culture media.
4. Pure water for hydrogen generators, indoor humidifiers, and high-pressure sterilizers.
5. Drinking water for laboratory animals, etc.
