Series 4200B floor mounted cabinet gas feeders are vacuum operated, solution feed, differential pressure regulated feeders available with either manual or automatic control.
The floor mounted gas feeder is enclosed in a corrosion-resistant Polystyrene cabinet. Five different flowmeter capacities ranging from 1000 to 8000 lb/day (20 kg/h to 150 kg/h) provide versatility in meeting gas flow requirements. Manual Series 4210B gas feed systems consist of a cabinet, vacuum regulator and an ejector, or chemical induction unit. When automatic control is required (Series 4240B), the CAPITAL CONTROLS® automatic valve responds to control signals from a flowmeter or PLC. If residual or flow plus residual control is needed, the CAPTROL® Model 1451 controller is used. This could be cabinet mounted or remote mounted. The controller receives signals from a water flow transmitter and/or chlorine residual analyzer. If multiple feed points are required, remote meter panels and additional ejectors are available. A vacuum switchover module is available to provide for uninterrupted service to 4000 lb/day (75 kg/h).
