Powell Control Systems
Powell has a variety of control
panel options available to upgrade existing bleach plants
and can supply a complete control system that has been designed, assembled, programmed,
and tested for your system. Since the upgrade updates the original wiring to provide
complete PLC control, a new unit eliminates the need for controllers and panel-mounted
indicators. All control and final indication is done with a color screen mounted
on the front of the panel. Additional screen displays can also be included to provide
remote indication and/or control. The control panel can also include a phone modem
to allow remote access via phone line or a VPN connection to allow remote access
via the Internet. This remote access allows
Powell personnel to provide technical assistance and programming enhancements instantly.
Features & Benefits of Control Panels
Increased reliability of the control system
- Reduces downtime and emergency maintenance service calls.
- The modern control system is more compact, uses less power and operates cooler than
- The technology is less affected by temperature extremes, vibration and other elements
typically found in an industrial setting.
Remote dial in via phone modem in the control Panel
- Powell personnel can troubleshoot the system and download programming enhancements,
minimizing service calls and down time.
Operator friendly control system with one touch startup and color display screen
- Reduces training requirements for new operators.
- Displays all relevant data in real time such as set points, flow rates, pressures,
temperatures and other critical measurements in a single 14" screen that is
laid out using color graphics.
- Eliminates the need for an operator to know how to control several different instruments
mounted to the bleach plant.
- Permissive screen shows the status of each required element for bleach production.
If the bleach plant will not start, an operator can instantly identify the cause
and take corrective action.
- Screens are provided for viewing alarm history, adjusting alarm set points, and
other functions. These are password protected to prevent unauthorized access.
Increased accuracy of the instrumentation
- Improved control of final product specifications and repeatability can reduce raw
- Allows for tighter tolerances with regard to excess caustic.
- Track usage of process water, caustic and chlorine to allow for greater inventory
- Trend data to project future inventory needs.
Expandable control system architecture
- Supports future automation, such as tank farm level monitoring, tank farm valve
management, or gas detection systems.
Tank Level Management System
Powell can design and engineer a complete tank level management system package.
This engineered package includes the necessary control system and communication
hardware, programming and components to continuously monitor the level and operate
the filling valves of existing bleach storage tanks. Once installed, this system
can be easily expanded by adding instruments and blocks of programming for each
new tank in service.
