2472/F77A3 ion exchange unit

Industrial-size ion-exchange unit: water passes through a housing filled with ion-exchange resin, and the ions dissolved in it are replaced by an equivalent amount of ions released by the media. Resin selection sets the specific task — softening, alkalinity reduction (decarbonization), partial or full desalination, nitrate or boron removal. Once the exchange capacity is exhausted, the controls run a regeneration cycle and return the unit to service.

Housings from 24 inches up are fitted with the larger Runxin valves — 2 and 3-inch connections, capacity from 10 to 50 m³/h. This group introduces side-mounted valves: they are set into the housing wall, which simplifies piping for tall columns and servicing from above. Such units are assembled for the specific flow rate and raw water quality, so housing, valve, and media volume are selected together.

Design 2472/F77A3: housing 24×72″, automatic Runxin F77A3 valve with water meter, up to 18.0 m³/h, top mounting. The valve is designed for softening — regeneration of the ion-exchange load with reagent solution. Weight 104.85 kg.

Configuration within the line: vessel size 2472 (24×72″) with control valve Runxin F77A3. On the same vessel size 2472 (24×72″) the line also offers Runxin F74Q3 and Runxin F74A3. The same control valve Runxin F77A3 is fitted on 3672, 4872, 3072 and 4272.

On vessel size 2472 the closest alternatives to Runxin F77A3 are Runxin F74Q3 (valve capacity up to 10 m³/h instead of up to 18.0 m³/h, weight 88.35 kg instead of 104.85 kg) and Runxin F74A3 (valve capacity up to 10 m³/h instead of up to 18.0 m³/h, weight 88.85 kg instead of 104.85 kg).
