Commercial Water Softeners
SWT™ Clock Controlled Water Softeners

Safe Water Technologies’ corrosion proof commercial water softeners are built utilizing SWT’s ProSoft™ Resin as the primary layer. These cationic ion exchange systems are designed to remove calcium and magnesium (hardness), and a host of other cations from the water. SWT takes care of the little extras such as: machined PVC distribution systems, oversized brine tanks, safety floats standard in 16” or larger systems, and an anthracite under-bedding for less channeling.
  • 100% corrosion proof plastic systems
  • All international voltages available
  • Adjustable 12 day clock controller
  • 10 year warranty on tank
  • Tanks feature 150 PSI operating pressure
  • Energy efficient controller uses less than $2.00 of electricity per year

In basic terms, crosslinkage refers to the resin beads physical strength or ability to withstand chemical attack from chlorine, resin bed cleaners, and caustics used in DI applications. To a lesser extent, a higher crosslink also gives resin slightly higher softening capacity and a better affinity for iron. Almost all standard softening resins in the market range from 6.5% to 8% crosslink. If the water softener is on a chlorinated system, or sitting outside where high temperatures can weaken resin, then lower crosslink resins have a tendency to breakdown, lose capacity, and turn mushy over time . Generally speaking, the higher the crosslink, the better (and more expensive) the resin. 10% crosslink resins are generally too expensive for residential use and are found in mostly DI and industrial applications.

Fine mesh resins, which are smaller than standard size resin beads, slightly increase the softeners capacity, speed up softening reaction time, and increases the ability to filter fine particles from the water supply. These are good for dual bed systems because they help retain the smaller, lighter anion resin beads on the top layer. They are also popular in cabinet style water softeners with shallower resin beds.
