| SWT’s Electronic Time Clock Controlled Commercial Water Softeners are built
utilizing our ProSoft™ resin as the primary
layer. This is the same resin SWT used to treat the water servicing the Capitol Building in Washington DC! |
| |
 |
SWT Water Softeners available
with Logix Series Valves (left)
or Tech Series Valves (right) |
|
|
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 float for 16 inch or larger systems, and an anthracite underbedding for less channeling.

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.
