Global Filtration Systems, Inc.
Backflushing and Disposable Filtration Technologies, Carbon Treatment, & Oil Extraction Units
|FULL AUTOMATION PACKAGES|
All the cost saving and safety features found on the manual AF Series units can be fully automated with the AF Series Automation Package. It provides complete, unattended filtration operation by utilizing a programmable logic controller (PLC) which automates the normal operating functions of the control unit. It monitors the filter to determine when it needs to be backflushed, controls the backflush operation, and monitors each operation performed while providing an alarm if a failure should occur. It also provides test and diagnostic routines to ease maintenance. The filter utilizes electrically actuated valves available in a range of duty cycles, with pneumatic actuation optional. Its backflushing operation provides cleaning flow to each individual filter sleeve.
Sensors monitor flow or pressure at the filter inlet, and can provide pump protection. Adjustable sensors are designed to send a signal to the PLC, which in turn initiates the back-flushing cycle. A backflush can also be initiated through a direct pushbutton interface and our backflush interval timer. A visible backflush counter is also mounted on the front panel and indicates the total number of backflush cycles.
AF Series automation systems can be easily configured to
operate in conjunction with automated processes and other automated
equipment. Filter status information is available at all times, and the
system will shut down (pump off, all valves closed) in response to any alarm
condition. The alarm will be initiated if any of the following systems
malfunction, and will immediately shut down and close all valves: valve and
valve position indication failure; improper pump flow; purge
malfunction/timeout; high or low level in processing tank. The system status
lights at the time of the malfunction will stay on, indicating in what mode
the failure occurred.
A NEMA-4X enclosure protects
the electronics, and the system uses sealed cable connections. It displays
illuminated valve and pump indication, along with all operating controls,
system status, and alarm lights. An audible alarm is provided on the
controller. An optional remote alarm is available.
