Easy to install for indoor installation, each Series WP840 wall panel is factory tested and needs no field adjustment prior to start-up. Six different flowmeter capacities ranging from 10 to 500 PPD (200 g/h to 10 kg/h) provide versatility in meeting gas flow requirements.
Wall panel gas feeders consist of a wall panel, vacuum regulator and an ejector, or chemical induction unit. The wall panel includes Capital Controls® automatic valve, gas flowmeter, controller and differential pressure regulator mounted on the corrosion-resistant, heavy-duty panel. The controller receives signals from a water flow transmitter and/ or chlorine residual analyzer. The automatic valve responds to signals from the CAPTROL® controller. If multiple feed points are required, gauged meter assemblies and additional ejectors are provided. Automatic switchover is available to provide for uninterrupted service.
