1665/F63C3 ion exchange unit

Ion-exchange unit for water treatment: 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. When the media's exchange capacity is exhausted, the controls run a regeneration cycle and the unit returns to service.

Housings from 14 to 21 inches are rated for flow rates where household-size valves are no longer enough: the line adds 2-inch Runxin valves with capacity up to 10 m³/h, alongside 3/4 and 1-inch models. Valve mounting in this group is top. A larger housing holds more resin, so for the same raw water the unit runs longer between regenerations.

Design 1665/F63C3: housing 16×65″, automatic Runxin F63C3 valve with water meter, up to 4.5 m³/h, 1" connection, top mounting. The valve is designed for softening — regeneration of the ion-exchange load with reagent solution. Weight 35.384 kg.

Configuration within the line: vessel size 1665 (16×65″) with control valve Runxin F63C3. On the same vessel size 1665 (16×65″) the line also offers Runxin F82B3, Runxin F116Q3, Runxin F63G3, Runxin F63P3 and others. The same control valve Runxin F63C3 is fitted on 0835, 0844, 1044, 1035 and others.

On vessel size 1665 the closest alternatives to Runxin F63C3 are Runxin F82B3 (valve capacity up to 3.5 m³/h instead of up to 4.5 m³/h), Runxin F116Q3 (weight 35.324 kg instead of 35.384 kg) and Runxin F63G3 (valve capacity up to 4.0 m³/h instead of up to 4.5 m³/h).
