The S10k™ chlorinator is a vacuum operated, sonically
regulated unit. Direct cylinder mounting puts the
vacuum-regulating valve right at the source, reducing
gas pressure to a vacuum immediately. It provides
for economic low capacity gas feed applications for
municipal and industrial water and wastewater treatment
and disinfection, swimming pools and industrial process
water. Its ability to handle all water treatment gases as
well as its flexible mounting configurations for cylinders,
manifolds or ton containers provides versatility for all
installations. Two basic arrangements are available in
capacities of 4 and 10 kilograms per hour / 200 and 500
pounds per day (PPD) of chlorine gas. With fewer internal
parts, you can be confident that the S10k™ will provide
reliable, dependable service.
Technical Data
Easy to Install, Operate and Maintain.
The S10k™ chlorinator is simple in design,
compact and easy to handle. Injector
installation only requires connecting
to a water supply and running plastic
tubing to a main or open channel. A knob
adjustment on the flowmeter changes gas
feed rate, which is indicated on a high
resolution 75 or 125 mm/3” or 5” scale.
Accuracy
Gas feed is ± 4% of the indicated flow.
Operating Range
Manual 20:1 for any flowmeter.
Automatic 10:1.
Distance, Supply to the Control Unit
For flexibility, it is not necessary to install
the vacuum regulating valve close to
the control unit. It can be up to several
hundred feet from the gas control unit,
depending on maximum feed rate, the
diameter of the connecting pipe or tubing
and system performance requirements.
Injector Operating Water
Injector operating water must be
reasonably clean. Injectors are fixedthroat
differential type. Maximum inlet
pressure is 20 bar/300 psi to a maximum
of 38°C/100ºF; 10 bar/150 psi to a
maximum of 54.4°C/130ºF.
Pressure at Application Point
Maximum pressure wi th hose or
polyethylene tubing is 5 bar/75 psi.
High pressure hose or rigid pipe will
allow application against back pressure
to 10.7 bar/160 psi.
A solution pump after the injector will allow
application against higher pressure.
Swimming Pools
For non-residential swimming pool
applications a unique package is
available.
Control Methods
Feed rate of any S10k™ gas feeder is
controlled by either one or both of these
methods: interrupting the injectorwater
supply to shut off the gas feeder’s
operating vacuum or changing V-Notch
orifice area (by positioning the v-grooved
plug in its ring) while holding vacuum
differential across the orifice constant.
Manual Control
Manual control by changing orifice area
(V-Notch plug position) via an adjustment
knob on chlorinator.
Start-Stop or Program Control
This type of control is achieved with simple
implementation. Operating vacuum is
started and stopped by interrupting the
injector water supply.
Automatic Control
The S10k™ can be provided with
automatic feed rate control ranging from
simple to complex control schemes. The
control system can consist of a simple
direct mA control V-Notch actuator or a
more sophisticated control including an
actuator and a controller (choice of either
a Multifunction Controller (MFC), a Signal
Conditioning Unit (SCU) or a Process
Control Unit (PCU).
