Commercial Heavy Duty
Water Softener – CWS200H

CWS200H water softeners are suitable

for commercial applications ranging from
100,000 to 600,000 grains of hardness re­moval capacity at ow rates up to 126 gpm.

Operation of the Softener - Hard water contains dissolved

minerals in the form of Calcium (Ca), Magnesium (Mg), and
Iron (Fe). An ion exchange process accomplishes removal of
these minerals. As water ows through the mineral tank, the
dissolved minerals become attached to the resin. Over a pe­riod of time the resin will become exhausted, and the softener
will regenerate using a brine solution.

Softening Media - The exchange media is a high quality

strong acid softener (Cation) resin with high whole bead count,
no color throw, and is chlorine resistant. The media combines
high operating capacity with excellent chemical and physical
stability for a long dependable life.

Regeneration Controller – These softeners feature the Watts

Enhanced Electronic controller. It combines simplicity with
exibility in a user-friendly package that is easy to setup and
operate. . Fully adjustable cycle times with 6-cycle control
allows for application specic settings. A turbine ow meter
provides accurate ow measurement and allows for efcient
operation. The H series controllers have the option of includ­ing the auxiliary system circuit board which allows up to four

units to be connected together for multiple tank applications.

Control Valve - The Watts 2.0” Heavy Duty control valve

operates on command from the valve controller. A hydrauli­cally balanced piston glides effortlessly along non-corrosive
spacers and seals to precise positions. The reliable and
proven DC drive performs in the toughest applications. The
lead free brass valve body is covered with an electro-statically
applied NSF/ FDA approved epoxy coating that resists corro­sion and maintains a quality appearance over time. The 2.0” H
valves include a built in turbine meter for ow monitoring. This
feature reduces the cost, simplies the installation, and saves
space.

Resin Tanks – All models feature non-corrosive berglass

tanks, with a one-piece thermoplastic inner liner. The tanks
are approved by NSF, UL, FDA, and meet WQA standard
S-100.

Brine System – The brine tank is made of tough, high-density

polyethylene. Brine tanks 24” in diameter and smaller feature
a grid plate for maximum saturation of brine. A high quality air
check prevents air from entering the system.

Note: Flow rates listed above are based on pressure drop only. Selecting a system based on pressure drop alone does not guarantee that the system
will provide adequately softened water. System selection should be based on resin quantity, capacity required, feed water analysis, and application
requirements.
