Commercial Heavy Duty  
Water Softener – CWS200H
CWS200H water softeners are suitable 
for commercial applications ranging from 
100,000 to 600,000 grains of hardness re-
moval 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 pe-
riod 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 specic settings. A turbine ow meter 
provides accurate ow measurement and allows for efcient 
operation. The H series controllers have the option of includ-
ing 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 hydrauli-
cally 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 corro-
sion 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, simplies 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.
