Flow Rates: Up to 55 gpm (208 lpm)
Watts Pure Water Series PWS15T water softening systems are
highly efficient, twin alternating, conventional cation exchange
type water softeners. They are designed to supply continuous
softened water without interruption.
Series PWS15T water softeners are suitable for commercial
applications ranging from 60,000 to 300,000 grains of hardness
removal per tank and flow rates up to 55 gallons per minute
(208 lpm). Regeneration is meter demand initiated. All cycles
of regeneration are fully automatic and do not require manual
actuation.
Watts Pure Water Series PWS15T water softeners are designed
for point of use or point of entry applications where the benefits
of softened water are required and water demand is round the
clock. 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, cooling tower make up water, sterilizer
make up water, washing, and process water are all common
applications for the Watts Pure Water Series PWS15T 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
Watts Pure Water Series PWS15T 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 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° - 43°C).
The system shall provide softened water measuring less than
one grain per gallon of hardness as Calcium Carbonate when
operated within the manufacturers operational specifications.
