ROC-8221 Single Stage Double Channels RO Controller
ROC-8221 is a combined control instrument of a single-stage reverse osmosis controller and double-channel on-line conductivity instrument.

ROC-8221 is a combined control instrument of a single-stage reverse osmosis controller and double-channel on-line conductivity instrument.

On-line analysis and process control of the oil refining, metallurgy,chemical synthesis industry process;

High Cost-Effective ,widely used for chemical industry,paper making industry,industrial coating,pharmaceutical,food,beverage,municipal water,Environmental and so on.

Versatile top or side mount is suitable for commercial or industrial applications
Backwash capacity accommodates tanks up to 63″ diameter
Flexible 7 or 12 day time clock or meter initiated regeneration
Ideal for most filter applications up to 42″

RF double tank floating bed plane multi-way valve, realized tow tank softening at the same time and regenerating alternate, integrated with brine jet device and brine flow meter and brine electric valve, with soft water flow meter, guarantees the water softening , the water regenerating and water filling to salt box, Complete according to the set volume.as long as the factory according to the raw water hardness set corresponding operation parameters, can always guarantee the stable operation of the equipment, guarantee the softened water and salt consumption.

Widely used for electric power,electronics,metallurgy,petrochemical,pharmaceutical ,food and beverage,environmental protection field .


Meter, time clock dual mode. In flow mode, the internal flow transmitter realizes the function of setting water volume as required. After setting regeneration water volume and cleaning water volume of exchange tank, the period of softening water amount (ton) according to the hardness of the raw water, each station decreases to “0” according to the set value, and stops decreasing and maintains when the water is out of service or no water.

Single stage RO controller used for conductivity monitoring and process program control .
