Datasheet: Model 4200 Gas Vacuum Chemical Feeder

The JCS Industries Model 4200 Gas Vacuum Chemcial Feeder mixes and feeds gaseous chemicals commonly used for water and wastewater disinfection accurately, reliably and safely. The system is comprised of a vacuum injector to safely introduce the gas into the feed-water stream, a reversing servo motor coupled with a V-notch valve to regulate the chemical flow rate, a calibrated rotameter to visually indicate the flow rate, and a control module for complete electronic control and communications.

Control Modes

Flow Proportional Control — An external 4-20mA DC signal is connected to the feeder. Chemical feed is controlled at a rate that is proportional to the incoming signal. Dosage control is available to adjust the feeder output 0.2 to 4.0 ratio.

Residual Control — An external 4-20mA DC signal from a residual analyzer is connected to the feeder. Chemical feed is controlled via the setup menu in the residual mode. Parameters, such as sample lag and target residual, are entered in the controller for responsive control.

Compound Loop Control — External 4-20mA DC signals from both flow meter and residual analyzer are connected to the feeder. Chemical feed is controlled via the setup menu in the compound loop mode. Parameters such as sample lag, target residual, and flow over-ride are entered in the Model 4200 Controller for responsive control.
