We constantly develop ASTM Type I ultrapure water system, lab reverse osmosis equipment, lab double ro water deionizer of different grades and prices to meet the needs of buyers with different demands. We actively expand domestic and international markets, and dig deeper into internal potential. Looking forward to the future, we are united and determined to carry forward the successful experience in the progress and promote the enterprise spirit of cooperation, enterprising, rigorous and innovative. In every stage of design, production and inspection, we have adopted advanced equipment and mature technical personnel. We introduce high-tech talents from multiple levels, angles and aspects, and focus on establishing an efficient talent selection mechanism.
Medium-1600 series is nearly the smallest water system, with the same output-250 liters/hour. It meets the requirements of water for production and central water supply.
Medium-1600RO is single stage RO water system, with LCD controlling system, 3 way water quality sensor, timing and quality dispensing, stainless steel shell. 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 and general grade experiments.

Medium-1600RO
Features and Advantages
Medium-1600 | Competitive product |
The voltage is only DC24V, lower than human safe voltage (DC36V) | The voltage is above of AC380V/220V, dangerous for operator |
2 sets 800 GPD pure water system, independent operation. If one was broken, the other also runs. | Only one system work. If going wrong, the machine could not work anymore. |
Working pressure of RO membrane<70PSI (4.9kgf/cm2), assure safety. | Working pressure of RO membrane >225PSI (15kgf/cm2), dangerous for operator |
Floor space is only 0.5m2, save more room for laboratory | The floor space is very large, waste the room of laboratory |
