Commercial Water Softeners
swtwater.com Computer Controlled Softeners
SWT’s Computer 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!

    Operating Pressure: 25 to 150 psi (1.7 to 10.3 bar)
    Operating Temperature: 36 to 120ºF (2 to 48.9ºC)
      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.
Single tank or twin alternating systems available
100% corrosion proof plastic systems
Energy efficient, computerized controller monitors and adjusts to actual water usage
Saves up to 60% in salt cost and usage
All components NSF listed
All international voltages available
10 year warranty on tanks, 5 year warranty on valves

NOTES:
All softeners for municipal water systems come with an upper screen as standard equipment. Other installation fittings are available on request.

Resin ratings are as follows:

SWT RESIN CROSSLINK     CaCO3 CAPACITY
@ 15 LB/CU.FT.
ProSoft™ Gold 7%   32,600
ProSoft™ Premium 8%   34,400
ProSoft™ Fine Mesh 8%   34,400
ProSoft™ Heavy Duty 10%   38,800
ProSoft™ High Porosity 12%   30,000

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.
