Series DCTE Photohelic® Switch/Gage On-Demand Cleaning Controller

Reverse Pulse-Jet Cleaning Initiated by Differential Pressure

The Photohelic® Pressure Switch/Gages On-Demand Cleaning Controller provides a simple, complete dust collection control all in one enclosure. The Photohelic® controller combined with the DCT500DC Timer Control provides a timed energization of solenoid valves when the differential pressure indicates filter cleaning is necessary. The operator can easily set the cleaning initiation and duration by adjusting the 2 set point knobs on the front face of the Photohelic® controller. Solenoid valve sequencing is also easily set via two potentiometers inside the enclosure on the timer board. A three position switch on the front of the enclosure offers cleaning versatility by allowing the user to select between on demand or continuous manual cleaning. The Photohelic® controller is pneumatically connected with tubing to fittings on the enclosure. All that is required for start-up is connection of tubing from the process to the external fittings on the enclosure, and wiring the solenoid valves to the timer board.
