High Purity Water Treatment Equipment RS-II

Xinrui Laboratory's high-purity water analysis instruments can almost completely remove conductive media from water, as well as reduce non-dissociating colloidal substances, gases, and organic matter to very low levels. The resistivity exceeds the limit of 10–18.3 MΩ·cm. Ultrapure water is a standard that is difficult to achieve with ordinary pure water equipment. It is typically produced using industrial high-purity water equipment through four major steps: pretreatment, reverse osmosis technology, high-purity treatment, and post-treatment. Multiple filtration methods, high-performance ion exchange (polishing), ultrafiltration filters, UV lamps, TOC removal devices, and other treatment methods are employed to achieve a resistivity of up to 18.25 MΩ·cm.
Detailed Introduction
Xinrui Laboratory's high-purity water analysis instruments are commonly used equipment in scientific laboratories, meeting the technical requirements for purified water in experiments.
Xinrui high-purity water analysis instruments are designed with different pretreatment functions, configured with various filtration units tailored to different water qualities, such as softening and strong activated carbon adsorption units for high hardness and high turbidity.
Small microcomputer control function: Operated by a small microcomputer, the machine automatically shuts down in cases of water shortage or full water levels and runs an automatic rinsing function upon each startup.
Compared to traditional electric thermal water distillers, it offers higher purity and stability in water output; simple operation without the need for dedicated personnel; no electric heating tubes, no scaling issues, and high safety.
Features of Xinrui Laboratory High-Purity Water Analysis Instrument System:
· Uses silent pumps, ensuring no vibration, noise, or electromagnetic radiation during operation, with no impact on the working environment.
· Employs reverse osmosis membranes, ensuring stable performance, high desalination rate, and long lifespan.
· Utilizes exchange resin for (ultra) purification columns, providing high exchange capacity and superior water quality.
· Features an all-metal chassis with electrostatic spray painting, effectively preventing corrosion from moisture.
· Separated water and electrical circuits, avoiding the impact of humid environments on electrical systems.

Product Features
1. Equipped with power indicator, pump operation indicator, low-pressure indicator, and system rinsing indicator functions.
2. Uses imported ion filtration membranes and high-pressure, silent pure water pumps, ensuring more reliable operation and broader applicability to water qualities.
3. Features a system rinsing function: Before water production upon startup, the system automatically rinses for 18 seconds before beginning water production.
4. Includes system protection function: The equipment automatically shuts down when water pressure is too low or there is no water, and automatically restarts when water supply resumes.
5. High output, low energy consumption, and electricity savings: Output of 20L/h with power consumption of only 25W, which is 1/300 of similar products.
6. Employs advanced water treatment processes, with a high-purity water output ratio of about 40% and low water consumption.
7. No electric heating tubes, no scaling issues, and no need for cleaning.
8. No heat loss; output water is at room temperature and requires no 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 output upgrades. 12. The RS-II series, in addition to the features and functions of the RS series high-purity water machines, also includes water quality monitoring, enabling real-time monitoring of output water conductivity and temperature.
Why Use High-Purity Water Machines
· Stable water quality output, simple testing methods, no need for repeated experiments.
· High water output, with basic models at 10L/H or 20L/H, up to 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 analytical experiment efficiency.
· Most importantly, the instrument operates at only 25 watts, significantly more energy-efficient compared to electric thermal water distillers, which typically consume 7–8 kW, commonly 10 kW, or even 15 kW, reducing daily operating costs.
