Working Principle of Xinrui Laboratory Ultrapure Water Machine:
The working principle of the laboratory ultrapure water machine involves pretreatment of tap water through precision filter cartridges and activated carbon cartridges to filter out particles such as sediment and adsorb odors, making the tap water cleaner. It then undergoes water purification and desalination via 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 device is discharged. Reverse osmosis purified water undergoes deep desalination through a purification column to obtain Grade 1 water or ultrapure water. Finally, 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. The precision filter cartridges, activated carbon cartridges, reverse osmosis membrane, and purification column are all materials with relative lifespans, with the precision and activated carbon cartridges serving to protect the reverse osmosis membrane.
Features of Xinrui Laboratory Ultrapure Water Machine
1. Control Function: Fully automatic touchscreen display controller with animated flowcharts, real-time display and monitoring of the operational status of each water treatment unit.
2. Online Display of Operational Status and Parameters: Flow rate, pressure, source water quality, and product water quality are monitored and displayed digitally, providing real-time insight into equipment operation for easy monitoring and analysis.
3. Automatic Protection and Alarm Functions: Self-check on startup, low-water protection alarm, automatic reset after power failure, automatic shutdown and handling for high/low pressure, system interlocking. If a local issue occurs, the system automatically shuts down.
4. The reverse osmosis main unit features an anti-scaling program design for the RO membrane, with timed cyclic flushing of the RO membrane surface to effectively protect its operation.
5. Fully automatic control of all tank liquid levels: Intermediate tanks, pure water tanks, and device connections between tanks not only achieve interlocking but also protect each pump from running dry and getting damaged.
6. Online Monitoring of Product Water Quality and Recirculation Treatment for Non-Compliant Water: To ensure water quality meets requirements at the point of use, the main unit's product water quality is monitored in real-time, with a feedback device for recirculating and reprocessing non-compliant water.
7. Equipped with an automatic pipeline flushing function to periodically clean the pipes, maintaining internal cleanliness. During flushing, water can be directly discharged or recirculated back to the main unit for reuse, conserving water.
RUPC Series Ultrapure Water Machine Performance Characteristics
■ Large color touchscreen display with a user-friendly interface for complete monitoring of instrument status and real-time data.
■ Fully automatic control, low-pressure alarm shutdown protection, 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, featuring ultra-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, customizable by the user.
■ Operates on low-voltage 24V DC power, 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, entering shutdown mode.
■ The instrument includes comprehensive alarm提示 functions, 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.
■ Simultaneous online monitoring of three water quality parameters,实时监测 source water, RO water, and ultrapure water quality.
■ Fully automatic RO membrane anti-scaling flushing program to extend membrane lifespan.
■ Freely startable and closable ultrapure water circulation system to maintain low bacterial contamination levels.
■ Integrated water circulation mode allows users to set minimum water quality standards. Water that does not meet requirements enters circulation mode until it qualifies.
■ The instrument features automatic event recording and statistics, including status and data at the time of events. After recovery, the controller saves data to memory for future review.
■ Special timed water withdrawal and quantitative water withdrawal functions.
■ Multiple规格 water storage tanks available to meet different needs.
■ Users can choose between constant-pressure tank storage or tankless water withdrawal.
■ Ergonomic chassis design compliant with GLP standards.
■ All pipelines are NSF certified with new quick-connect fittings for easier filter column replacement and maintenance.
■ Original imported nuclear-grade resin and fully descending flow ultrapurification column design ensure top-tier water quality at all times.
