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.

Flexible 7 or 12 day time clock or meter initiated regeneration
Fully adjustable, 5-cycle control delivers upflow back wash, downflow brining, slow rinse, rapid rinse and down flow service
Designed for single tank or multi-tank systems, alternating or interlocking
Continuous flow rate of 250 GPM

Salt and water savings by using 100% capacity of the tank in service before switching to the second tank
Regenerates immediately when needed for continuous soft water
Corrosion-free fiber-reinforced polymer valve body

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

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.


Measure range :TUR-6101 (0~5NTU) ;TUR-6102 (0~100NTU)

“One Dynamic and Two Static” Double Static Ceramics Plates Multi-port Valve is on behalf of another beginning in the field of water treatment control, which can overcome many disadvantages of traditional products in installation.

Applicable to all kinds of small and medium-sized single-stage, double-stage reverse osmosis control system. With simple operation, complete measurement and configuration, highly integrated system
