Twin Water Softeners with Metered Valves
Ideal for situations where uninterrupted flow of soft water is a must, our twin softeners consist of two resin tanks. One resin tank is always in service, while the other tank is in standby. When the meter determines that the resin is near its capacity, it will switch the tank in standby to be in service, and the tank containing the exhausted resin switches into regeneration, and then into standby.

*5 gpm per sq.ft. of water softener media is the best design condition for filtration. For relatively clean water, you may go up to design criteria of 15 gpm per sq. ft. Backwash flow rate for water softener is based on 25 psi pressure drop.
***Please add the appropriate voltage code to the end of the water softener model number when ordering. Example: W-S940ST-116
110v/60Hz = 116 |
220v/60Hz = 216 |
220v/50Hz = 215 |
Notes:
- Twin systems are configured for alternate regeneration.
