Twin Electronic Volumetric Head F73
Runxin's F73 twin volumetric electronic head (valve) has a pulsating flowmeter (turbine type) and when the user-set liters (cubic degree base) are consumed, the first column resin regeneration process begins. At the same time, the valve turns on the second column and in this way ensures uninterrupted operation of softened water.
The regeneration process takes place in 4 cycles, all of which are configurable:
- Backwash : Resin preparation. The resin is rinsed in the maximum flow of water to prepare it for the next step. We usually set it from 3 to 8 minutes depending on the installation.
- Brine & Slow Rinse : In this stage the head draws the salt water (sodium chloride) from the brine tank and irrigates the resin with it. It is the longest stage and lasts at least 60 minutes.
- Brine Refill: The head refills the brine tank with water. This process takes from 3 to 10 minutes depending on the installation.
- Fast Rinse : The resin is rinsed at maximum flow to remove salt residue and return to its original state ready to deliver softened water again. This process takes from 5 to 10 minutes depending on the installation.
Dupont DOW DOWEX HCR-S/S Softening Resin
Dupont Dow Chemicals is the world's largest resin manufacturer. Based in USA, it counts over 600 resins specialized for hundreds of applications.
The resin we use DOWEX HCR-S/S is a strong cationic suitable for potable water softening applications. It is WQA certified to NSF/ANSI-61 and complies with the US FDA Regulation 21 CFR 173.25. The resin absorbs the Calcium Ca2+ and Magnesium Mg2+ ions, elements which make up the hardness of the water, the so-called salts. The resin is charged with Na+ ions and has a total capacity of 1.9 eq/L. Each time it becomes saturated it will need regeneration with >99.5% purity sodium chloride (salt).
