Medium-R series is standard double stage reverse osmosis system. With 2 stage pump, 2 stage RO membrane and buffer tank, system achieves stable water quality, little drain, and low running cost.
Compared with single stage RO system, the quality of RO water is better, and the running cost is lower for less consumables replacement. Moreover, compared with simple 2nd stage RO system (1 pump, 2 RO membrane, without buffer tank), its system design is more rational, and the RO quality is more stable. Even though with the worse source water, the 2nd stage RO water’s conductivity also can stay 1-5µs/cm.
Medium-RRO series is 2nd stage RO water system, with LCD controlling system, 3 way water quality sensor, cartridge replacing alarm, timing and quality dispensing, stainless steel shell, built-in 2 set tanks (buffer tank and pressure tank). Its output ranges from 30 to 90 liters/hour. And the 2nd stage RO water’s conductivity can stay 1-5µs/cm, suitable for glassware washing and general grade experiments.

Models:
Medium-RRO 30 / 45 / 60 / 90
Features and Advantages
Automatic microcomputer controlling system, LED real-time animation mode display.
Running status is showed in the LED display, such as flushing, producing water, water full, water shortage, and check service.
Power on self-test, power reset, alarm when work more than 6 hours continuously, water shortage, leakage, low and high pressure.
With 2 pumps, 2 RO membranes and buffer tank, system assures 2nd stage RO water quality´s stability from different source water, and achieves little drain and low running cost.
3 procedure of the reverse osmosis membrane´s self-flushing: power on, water shortage reset and work more than 2 hours continuously, extend the life of RO membrane.
On-line conductivity monitor, with apheliotropic LCD display, to detect the quality of reverse osmosis water.
Attached portable TDS (total dissolved solid)/conductivity test pen, with dry cell design, to detect the quality of feed water and RO water.
High-capacity and independent cartridges design, with fast inserted adapters, easy to replace, and achieve running in the lowest cost.
Built-in 15 liters airtight plastic pressure water tank and buffer tank, save more lab space, easier for installation and maintenance.
Stainless steel shell with powder painting technics, achieve elegant appearance and meeting GLP standard.
External water tanks is optional to meet different need and assure ample water-supply.
Floor type with wheels on the bottom design, convenient to move.
3 door and easy-to-replacing cartridge design, convenient to maintain system and replace cartridges.
Tube and adapter with NSF authorization and top quality, reduce TOC level and assure water´s quality.
Long life and high-capacity pretreatment (including PP fiber, and active carbon cartridge), effectively protect RO membrane.
RO module with DOW´s membrane, ensure long life, stable operation and high desalinization rate.
