Commercial Water Softening Systems
Connection Size: 2" (50 mm)
Flow Rates: Up to 119 gpm (450 lpm)
Watts CWS200 water softening systems are highly efficient cation
exchange type water softeners. They are suitable for commercial
applications ranging from 60,000 to 600,000 grains of hardness
removal and flow rates up to 119 gallons per minute. Regeneration
is meter demand initiated. All cycles of regeneration are fully automatic and do not require manual actuation.
Watts CWS200 water softeners are designed for point of use or
point of entry applications where the benefits of softened water
are required. These systems exchange scale forming calcium and
magnesium ions with non-scale forming sodium ions to create soft
water for a variety of applications. Steam boiler make up water,
water heater pretreatment, reverse osmosis pretreatment, sterilizer
make up water, washing, and process water are all common applications for the Watts CWS200 water softeners.
Softened water provides a wide variety of benefits from not introducing scale into pipes, valves, water heating equipment, heat
exchangers, and cooling towers to reducing mineral build up in
areas that see excessive splashing such as food preparation counters and sink areas. Softened water also conserves soaps and
cleaning agents by eliminating the formation of soap curd, so your
cleaners can work on cleaning not reacting with the hardness in
your water.

Specifications
A Watts CWS200 water softening system shall be installed on
the building’s main water line just after it enters the building. The
installation point shall be after any backflow prevention or pressure
regulating valves. Other installation options are to install a system
just before the water heater or other types of equipment needing
the protection of softened water. In installations where dedicated
cold water make up to a water heater is the installation point, a
backflow preventer and a thermal expansion tank must be installed
as well. The system shall be installed with a bypass valve to allow
for the shut down and removal of the unit without interrupting the
water supply to the building. The water softener shall be a down
flow regenerated, metered demand, sodium cycle cation exchange
type system with all components necessary for proper operation. Electrical requirements are 120 volt 60 hertz. A local drain is
required to accept drain water from the system. The feed water
pressure must not fall below 25psi or exceed 125psi. Water tem-
perature must not fall below 34°F or exceed 110°F (1 - 43°C). The
system shall provide softened water measuring less than one grain
per gallon of hardness as Calcium Carbonate when operated within
the resin manufacturer’s operational specifications.
Note: Do not use with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or after the
system.
Watts product specifications in U.S. customary units and metric are approximate and are provided for reference only. For precise measurements,

Note: Capacities are based on resin manufacturer’s data and are dependent upon influent water TDS, temperature, bed depth, and
flow rates. Feed water must be free of oil and color. Pipe size, tank size, and space requirements are in inches. Capacities and flow rates
expressed above are per tank. Flow rates listed at 25psi drops are for intermittent peak flow rates and are not to be used as continuous flows.
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 proved adequately softened water. System selection should be based on resin quantity, capacity required, feed water analysis, and application requirements.
