Gas Feeders, Vacuum
Series WP840LX Automatic Gas Feeder upto 10 Kg/hr.
- Worldwide standard for gas feeder technology
- Space saving wall panel design
- Variable capacities up to 500 PPD (10 kg/h)
- Microprocessor based automatic controls
- Remote vacuum regulator mounting
- Automatic switchover gives uninterrupted service.
WP840LX Gas Feeders are wall panel mounted and vacuum operated.
Best in class indoor installation, each Series WP840LX wall panel is factory tested and needs no field adjustment prior to start-up. Seven different flowmeter capacities ranging from 10 to 500 PPD (200 g/h to I 0 kg/h) provide versatility in meeting gas flow requirements.
Wall panel gas feeders consist of a wall panel, vacuum regulator and an ejector. The wall panel includes an 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 controller. If multiple feed points are required, remote meter panels and additional ejectors are provided.
DESIGN FEATURES
- Flow: Proportioning valve position to process flow.
- Residual: Single, integral action, opening valve based on residual set point.
- Compound Loop: Simultaneous proportioning valve position to a combination of flow proportioning and residual control. If one signal is lost, the controller automatically proportions based on remaining signal.
- Feed Forward: Valve position control directly proportional to flow signal multiplied by residual signal, provided by built-in multiplier Automatic wall panel units include: – Controller, automatic linear gas feeder control valve with electronic manual adjustment switch, flowmeter and differential pressure regulator.
APPLICATIONS
For process water, waste treatment and water treatment in the municipal or industrial marketplace.
- Disinfection: Potable water, municipal wastewater.
- Slime and algae control: Irrigation system, cooling towers
- Process water: Chemical and pharmaceutical manufacture, food (wash down, canning, bleaching, taste and odor control)
- Technologically Advanced: Capco Water controller provides microprocessor-based control, fully field configurable with gas flow output signal. The controller accepts a signal from the flow sensor and/or residual analyzer. An automatic linearized gas feeder control valve is provided for reliable control.
