Commercial Water Softening

Systems

Connection Size: 2" (50mm)

Flow Rates: Up to 105 gpm (397 lpm)

Watts Pure Water Series PWS20 and PWS20-2 water softening

systems are highly efficient conventional cation exchange type

water softeners. They are suitable for commercial applications

ranging from 90,000 to 600,000 grains of hardness removal

per tank and flow rates up to 105 gallons per minute (397 lpm).

Where continuous softened water is required PWS20-2 duplex

alternating systems can be specified for uninterrupted service.

Regeneration is meter demand initiated. All cycles of regenera-

tion are fully automatic and do not require manual actuation.

Watts Pure Water Series PWS20 and PWS20-2 water soften-

ers are designed for point of use or point of entry applications

where the benefits of softened water are required. These sys-

tems 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, cooling tower make up water,

sterilizer make up water, washing, and process water are all

common applications for the Watts Pure Water Series PWS20

and PWS20-2 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 Pure Water Series PWS20 and PWS20-2 water soft-

ening 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 with-

out 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 require-

ments 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 temperature must not

fall below 34°F or exceed 110°F (1°C - 43°C).

The system shall provide softened water measuring less than

one grain per gallon of hardness as Calcium Carbonate when

operated within the manufacturer’s operational specifications.
