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-1600S is ultrapure water system, with LCD controlling system, 2 way water quality sensor, timing and quality dispensing, stainless steel shell. The single stage RO water’s ion rejection rate is more than 97%, and the ultrapure water’s resistivity absolutely reaches to 18.2MΩ.cm. It completely meets the highest grade I standard of ASTM, CAP, CLSI, EP and USP.

Medium-1600S
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 |
