Product Features
1. Equipped with power indicator, pump operation indicator, low-pressure indicator, and system rinse 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 rinse function: before producing water each time the machine is turned on, it automatically rinses for 18 seconds before the system begins water production.
4. Includes a system protection function: when water pressure is too low or there is no water, the equipment automatically shuts down; when water supply resumes, the equipment automatically starts.
5. High output, low energy consumption, and power savings: water output of 20L/h with power consumption of 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, 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 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, basic models at 10L/H or 20L/H, up to a maximum of 100L/H.
· Output water at room temperature, requires no cooling, can be used directly, reducing experiment analysis time and avoiding secondary pollution during cooling.
· Water production on demand, avoiding time wasted during transportation and speeding up analysis 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.
Advantages Compared to 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 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 such as dry firing and tube explosion 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 microbiological culture medium preparation.
4. Pure water for hydrogen generators, indoor humidifiers, and high-pressure sterilizers.
5. Drinking water for laboratory animals, etc.
