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

Typical applications • Widely used in thermal boiler deaerator water and large and medium-sized industrial boiler feed water; • Operational supervision of reactor Primary circuit, secondary circuit circuits and condensate system; • On-line analysis of dissolved oxygen in circulating water of heat exchange system; • Deaeration control of marine fresh water system, thermal system and…

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.

BSQ-MINI is widely used in metallurgical manufacturing, electric power, light industry, textile, water treatment equipment, tap water pipe network and scientific research and other industrial sectors.
