Purge And Pressurization System Operates In Highly Corrosive Environments

Dec. 17, 2010
The 5000Q purge and pressurization system also allows the direct connection of PT100 RTD temperature sensors, which provide alarm contact outputs for user configurable set points.

Pepperl+Fuchs introduces the 5000Q purge and pressurization system, the latest addition to the company's family of purge and pressurization products. With a robust display screen and intuitive menus, the field-configurable 5000Q system was designed to facilitate simple installation and safe, seamless operation of general-purpose equipment mounted in certified enclosures within Zone 2  or  Zone 22 hazardous areas.
 
The 5000Q comes in a compact size at 122 mm x 120 mm x 90 mm and components designed to mount easily to existing enclosures. It also comes equipped with an integral pressure sensor that enables automatic purging and pressurization through the digital solenoid valve.

The 5000Q purge and pressurization system also allows the direct connection of PT100 RTD temperature sensors, which provide alarm contact outputs for user configurable set points. Should the temperature exceed these set points, the digital valve will activate to automatically cool the enclosure's interior.


The principle behind a purge and pressurization system is to ensure that the inside of the enclosure is safe by keeping the corrosive, dusty, and potentially explosive atmosphere from penetrating the enclosure through an overpressure within the enclosure.
