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.


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.

CL-9500 residual chlorine controller is a new controller. This meter has a high degree of intelligence and flexibility. It can measure Residual chlorine value and temperature at the same time. It is widely used in urban sewage treatment plants, water supply and other industries and can continuously measure the Residual chlorine value of solution.


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

This series of brine valves have overcome the deficiency of the products existing in the market. It can not only protect water injection and check the air, but also can limit the extreme amount of water injection and filter the water running inside. If water injection is too fast, the liquid level inside the brine well will spill out quickly and the injection has to be shut down, which will result in the insufficiency of water inside the brine tank and have bad influence upon the outcome of recycling. This kind of brine valves depends on water pressure to work. It is reliable in working and valuable in extensive employment.

1) Working Position : Filter->Back Wash->Fast Rinse->Filter
2) Using ceramic moving valve disk , small rotation torque
3) Abrasion resistance of the sealing surface, outstanding and long-lived deal.
4) It could be operated with pressure directly.

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

Incorporates 2 time-tested, hydraulically-balanced pistons to independently pilot service flow and regeneration
For use with single or multiple tank systems
Backwashes softener tanks up to 36″ diameter
Continuous flow rate of 106 GPM

Widely used for online measurement of acid&alkali in low concentrations and the low viscosity single-phase fluid of non-trade settlement process.
