Commercial Water Softening Systems

Connection Size: 1 Flow Rates: Up to 68 gpm (257 lpm)

Watts CWS150 water softening systems are highly efficient cation exchange type water softeners. They are suitable for commercial applications ranging from 40,000 to 300,000 grains of hardness removal and flow rates up to 68 (257 lpm) gallons per minute. Regeneration is meter demand initiated. All cycles of regeneration are fully automatic and do not require manual actuation.

Watts CWS150 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 CWS150 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 prepara-tion 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 CWS150 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, please contact Watts Technical Service. Watts reserves the right to change or modify product design, construction, specifications, or materials without prior notice and without incurring any obligation to make such changes and modifications on Watts products previously or subsequently sold.

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.
