With microcomputer controlling system in LED display, stainless steel shell, built-in 2 set pressure tanks, single stage RO system, 1 pump, portable TDS test pen and on-line conductivity monitor, Medium-RO series reverse osmosis water system is economic choice of RO water’s mass usage for general glassware washing.
With tap water inlet, its output ranges from 45 to 125 liters/hour. It can produce single stage RO water. The single stage RO water’s ion rejection rate is more than 97% (new RO membrane), organic rejection rate>99% (when mw>200 Dalton), particles and bacteria rejection rate>99%. It is suitable for glassware washing, feed of ultrapure water system, autoclave sterilizer, constant temperature and humidity chamber, salt spray test chamber, dampening machine and etc.

Models:
Medium-RO 300 / 400 / 600 / 800
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.
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 2 set 15 liters airtight plastic pressure water 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.
