Control Panels, Instrumentation & Controls

Powell Control Panels

Control Panels - Powell Fabrication & Manufacturing, Inc.

Powell Control Panels are fabricated and programmed on-site, using current Allen-Bradley control and communication technology. Enhancements available include the following: phone modems that allow for on-line programming enhancements and enable Powell personnel to provide technical assistance; paging capabilities that alert plant staff to critical after-hours alarms; and one-touch startup and color display screens for operator interface.

Tank Level
Management System

Tank Level Management System - Powell Fabrication & Manufacturing, Inc.

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.

Bleach Plant
Control Panel Upgrade

Bleach Plant Control Panel Upgrade
Powell has a variety of control panel options available to upgrade existing bleach plants and can supply a complete bleach plant control system that has been designed, assembled, programmed and tested for your bleach plant. 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.

Features & Benefits of Control Panels

Feature	Benefit
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 previous devices. 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 material consumption. Allows for tighter tolerances with regard to excess caustic. Track usage of process water, caustic and chlorine to allow for greater inventory accuracy. 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.
