Laboratory Central Water Supply System University TypeUltrapure Water SystemFunctional Features

1. Adopting microcomputer fully automatic control design, LCD large screen Chinese LCD display, menu based operation mode;

2. It has functions such as power on self-test, water shortage protection alarm, automatic power outage reset, automatic shutdown when the water tank is full, and high/low voltage overload protection. RO membrane automatic flushing, automatic water production and shutdown, and has pure water preparation and standby functions, without the need for dedicated personnel supervision;

3. The equipment adopts fully automatic programming control, a 3.5-inch Chinese LCD display screen, a capacitive tempered glass touch button design, high sensitivity, durability, and no worries about button damage, highlighting beauty and atmosphere;

4. Adopting a built-in 20 inch three-level pretreatment system, it can effectively remove impurities and suspended particulate matter from raw water, reduce organic matter and residual chlorine pollutants in raw water; The high-pressure pump adopts a domestic manufacturer, and the pump body material is SUS304 stainless steel, with a flow rate of ≥ 2m3/h. The reverse osmosis system adopts reverse osmosis membrane elements;

5. Equipped with a built-in 735 large capacity tank type purification+ultra purification system, it has a longer service life and more stable water quality;

6. The system has two water intake ports, which can simultaneously access two types of water quality: pure water and ultrapure water. Dual channel dual display function, real-time monitoring and display of RO pure water conductivity, UP ultra pure water resistivity, and total organic carbon content (TOC). RO pure water measurement range 0-20 μ S/cm (online monitoring), UP ultra pure water measurement range 0-18.25M Ω. cm (online monitoring), resistance cell sensitivity constant ≤ 0.01cm-1, temperature sensitivity ≤ ± 0.1 ℃, automatic water temperature compensation function to improve water quality accuracy;

7. It has the ability to monitor the operating pressure of raw water and reverse osmosis membranes, and can observe the system's operating pressure and status at any time;

8. The system has the function of circulating ultrapure water that does not meet the standard, maintaining the low bacterial pollution requirements of the system; The loop function can be freely turned on and off, and the loop upper limit value can be freely set;

9. Equipped with UP ultra pure water over standard discharge setting function, human voice alarm and replacement prompt function for consumables failure (the upper limit value of consumables failure can be set according to customer requirements), automatic fault detection, providing safety guarantee;

10. The system has the function of timed and quantitative water intake from 0-9999ml;

11. Equipped with one built-in pure water tank with a capacity of 100 liters, made of food grade PE material. The water tank is equipped with three levels of liquid level control: high, medium, and low. The equipment connection between the host and the water tank not only realizes linkage, but also protects the conveying pump from damage due to idling;

12. The system has the function of storing and querying historical data, which can effectively and accurately record and query historical data such as water intake time (year/month/day/hour/minute), water intake volume (ml), and water intake quality;

13. The system has a timed power on/off function, allowing users to freely set the power on or off time. It also has the function of displaying the current date and clock, as well as setting the time;

14. The system is equipped with a second level PIN password protection, which can set a startup password and a user operation password. The device management and usage rights are separated to prevent unauthorized personnel from operating;

15. The host adopts a carbon steel spray painted integrated cabinet design, supported by universal balance wheels, and equipped with five side access doors for easy equipment maintenance. It has an exquisite appearance, compact structural layout, small footprint, and effectively saves space.
