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 applicability to water quality.
3. Features a system flushing function: Before each startup for water production, the system automatically flushes for 18 seconds before beginning water production.
4. Includes a system protection function: The equipment automatically shuts down when water pressure is too low or there is no water, and automatically starts up when the water source is available.
5. High output, low energy consumption, and power savings: Output water volume of 20L/h, power consumption only 25W, which is 1/300 of similar products.
6. Utilizes advanced water treatment processes, 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; output water is at room temperature and does not require cooling, making it directly usable 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 quantity 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 output quality, simple testing methods, no need for repeated experiments.
· High water output, with basic models at 10L/H or 20L/H, and maximum output up to 100L/H.
· Output water at room temperature, no cooling required, directly usable, reducing experiment 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, making it more energy-efficient compared to electric thermal distillers that typically consume 7-8 kW, commonly 10 kW, or even 15 kW, reducing daily operating costs.
· For more comparisons with traditional electric thermal distillers, see the next section.
Advantages Compared to Traditional Electric Thermal 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 output volume) Single distillation, more for double-distilled water 1:4 (1 is output volume)
Water Stability Low output water purity, unstable High output water purity, strong stability
Operability Inconvenient operation, requires dedicated personnel Simple operation, no need for dedicated personnel
Safety Risks of dry firing, tube explosions, etc. No electric heating tube, no scaling issues, good safety

Main Uses of High-Purity Water:
1. Final rinsing of laboratory glassware.
2. Water for buffer solutions and chemical reagent preparation.
3. Water for microbial culture medium preparation.
4. Pure water for hydrogen generators, indoor humidifiers, and high-pressure sterilizers.
5. Drinking water for laboratory animals, etc.
