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). Direct 4-20mA input control (see WT.040.050.000.UA.PS) Direct 4-20mA input signal from an external control device Compact integral design Internal dosage capability MFC (see WT.050.580.000.US.PS) Direct flow proportional control or control adjustments Single feedback or direct residual closed-loop control Compound loop control Set point trim control Outputs: standard outputs of the MFC consists of four individual 0/4-20mA outputs, RS-485 digital communications SCU (see WT.040.100.000.UA.PS) Operating Modes: flow proportional, manual Inputs: 4-20mA DC (from flow transmitter) Outputs: Control out to actuator; also 4-20mA output for retransmission of gas feed rate (actuator position) Control Capability: Dosage and flow scaling PCU (see WT.040.200.000.UA.PS) Operating Modes: direct residual feed back, compound loop, feed forward, flow proportional, manual Ranges: Set points up to 50mg/L and center-zero capability for dechlorination Inputs: up to 3 analog (flow, residual, spare); 2 digital Outputs: Control out to actuator; plus user-configurable 4-20mA; RS-485 serial communications Control Logic: Proportional and integral with process time Alarms: Four user-configurable for 16 different conditions
