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. 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 water 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 at room temperature 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, with basic models at 10L/H or 20L/H, up to a maximum of 100L/H.
· Output water at room temperature requires no cooling and can be used directly, 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, significantly more energy-efficient compared to electric thermal distillers, which 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 water volume) for single distillation, more for double-distilled water; 1:4 (1 is output water 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 burning 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 preparing buffers and chemical reagents.
3. Water for preparing microbial culture media.
4. Pure water for hydrogen generators, indoor humidifiers, and high-pressure sterilizers.
5. Drinking water for laboratory animals, etc.
