: 6500-01-*-PNO-LNO

The 6500 series purge and pressurization system consists of a control unit, an EPV-6500 enclosure protection vent, and a valve for pressurization, purging, and, with some models, dilution for analyzer applications.

The compact 6500 control unit features an LCD user interface with sealed capacitive touch buttons. LEDs provide quick indication of the system status. The control unit has an input for a 2-wire RTD for temperature control/monitoring. Models are available that allow the user interface to be panel mounted to an enclosure wall or mounted onto the exterior of the enclosure. A HART output allows the control unit to be connected to a PC using PACTware or the customer’s AMS for remote monitoring. An app for Android, BlackBerry, and Apple devices allows connectivity via Bluetooth®.
