Ultrapure Water Purification System RUPC

A laboratory ultrapure water machine is a water purification device that removes all solid impurities, salt ions, bacteria, viruses, and other contaminants from water through methods such as filtration, reverse osmosis, electrodialysis, ion exchange, and ultraviolet sterilization.
Laboratory ultrapure water equipment is widely used in industries such as pharmaceuticals, electronics, chemicals, and biological and chemical laboratories. Laboratory ultrapure water machines typically produce two types of water: pure water and ultrapure water.
Working Principle of Laboratory Ultrapure Water Machines
The working principle of a laboratory ultrapure water machine involves pretreating tap water with precision filter cartridges and activated carbon cartridges to filter out particles like sediment and adsorb odors, making the tap water cleaner. The water then undergoes purification and desalination through a reverse osmosis device. The purified water is stored in a storage tank, meeting the national tertiary water standard, while the wastewater from the reverse osmosis process is discharged. Reverse osmosis purified water is further desalinated through purification columns to produce Grade 1 water or ultrapure water. If there are special requirements, ultraviolet sterilization or microfiltration/ultrafiltration devices are added after the ultrapure water stage to remove residual bacteria, particles, pyrogens, etc. Precision filter cartridges, activated carbon cartridges, reverse osmosis membranes, and purification columns are materials with limited lifespans. The precision filter and activated carbon cartridges primarily protect the reverse osmosis membrane.
Features of Xinrui Water Treatment Ultrapure Water Instruments
1. Equipped with a complete purification unit, it takes tap water as input and produces pure water and ultrapure water as output. It generates water of different standards to meet various laboratory water needs.
2. The new laboratory ultrapure water machine produces 40 times more ultrapure water per unit compared to similar imported products, with a water production cost one-fiftieth of other products.
3. If the source water quality is below 2000μs and hardness ≤450ppm, the output water quality can be stabilized below 5μs/cm, with a source water utilization rate of 60%-80%.
4. Users can quantitatively draw pure water and ultrapure water. By setting the desired volume, the ultrapure water machine automatically produces the appropriate amount of water. The draw volume can be freely set from 10 milliliters to 200 liters, with quantitative accuracy of ±2ml.
5. Users can store and query data in real-time through the fully intelligent monitoring system, enabling trend analysis. The system supports multiple languages, multiple users, and separate data recording.
6. Features a true-color LCD touchscreen with a graphical human-machine interface, allowing one-step operation and online information query. All monitoring data is collected in real-time and can be viewed online without external computer storage. Data storage capacity exceeds one year.
7. Consumables for the purification unit are reasonably placed, and components are plug-and-play, facilitating calibration, maintenance, cleaning, disinfection, and sampling during system validation.
Performance Features of the RUPC Series Ultrapure Water Machine
■ Large color touchscreen display and user-friendly interface enable full monitoring of the instrument's working status and real-time data.
■ Fully automatic control, low-pressure alarm shutdown protection, and automatic stop of water production when the tank is full.
■ Fully automatic microcomputer control system with multi-level menu operation. The controller uses a 32-bit low-power processor as the core, offering high computing speed and low power consumption. It integrates analog sensor inputs, switch signal inputs, control outputs, and online monitoring of water conductivity, resistivity, flow rate, pressure, and tank level.
■ Four-digit user password protection, which can be modified by the user.
■ Operates on low-voltage 24VDC power supply, complying with safety standards and suitable for humid environments without posing harm to users.
■ Features timed standby and automatic shutdown functions. After the shutdown time elapses, all outputs stop automatically, entering shutdown mode.
■ Comprehensive alarm提示功能, including low-pressure alarms, source water quality alarms, pure water quality alarms, ultrapure water quality alarms, and consumable expiration alarms. When an alarm occurs, the alarm menu interface automatically pops up, displaying current alarm information.
■ Simultaneously monitors three water quality parameters online,实时监测 source water, RO water, and ultrapure water quality.
■ Fully automatic RO membrane anti-scaling rinse program to extend the RO membrane's lifespan.
■ Ultrapure water circulation system that can be freely activated or deactivated to maintain low bacterial contamination levels.
■ Integrated water circulation mode allows users to set water quality standards. Water that does not meet requirements enters circulation mode until it meets standards.
■ Automatic event recording and statistics功能, including the status and data at the time of the event. After the event is resolved, the controller records the data in memory for future review.
■ Special timed water drawing and quantitative water drawing functions.
■ Multiple storage tank specifications available to meet different needs.
■ Users can choose between constant-pressure tank storage or tankless water drawing.
■ Ergonomically designed chassis compliant with GLP standards.
■ All pipelines are NSF-certified, with new quick-connect fittings for easier filter column replacement and maintenance.
■ Imported nuclear-grade resin and fully descending flow ultrapurification column design ensure consistent water quality.
□ Equipped with USB HOST interface and micro-printer interface for real-time storage and printing of historical data.
□ Dual-wavelength (185nm & 254nm) imported UV lamp effectively sterilizes, reduces TOC, and expands system applicability (optional).
□ Imported 0.45µm PES polyethersulfone composite membrane terminal sterilizing filter ensures sterile water quality (optional).
