Series CWS200

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 auto-

matic 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 appli-

cations for the Watts CWS200 water softeners.

Softened water provides a wide variety of benefits from not intro-

ducing 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 coun-

ters 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 opera-

tion. 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.

Watts product specifications in U.S. customary units and metric are approximate and are provided for reference only. For precise measurements,

please contact Watts Technical Service. Watts reserves the right to change or modify product design, construction, specifications, or materials with-

out prior notice and without incurring any obligation to make such changes and modifications on Watts products previously or subsequently sold.

Note: Do not use with water that is microbiologically unsafe or of

unknown quality without adequate disinfection before or after the

system.
