Purge and Pressurization Systems to Prevent Dust Explosions from Pepperl+Fuchs

Purge and Pressurization Systems to Prevent Dust Explosions from Pepperl+Fuchs
Pepperl+Fuchs is launching 2 dust-certified purge and pressurization systems: the high-end 6000 series and the economical, compact 5000 Q

The 6000 series is certified for gas or dust atmospheres and holds Class I/II/Division 1, ATEX and IECEx certifications for zone 1/21. The new dust-certified enclosure of the 6000 series features a separate stainless steel enclosure to house the user interface, the I.S. terminal block and the optional temperature modules.

The IP66 enclosure is an accessory to the 6000 series component kit, which can be mounted and used in the dust zone. The component kit allows the 6000 series purge system to be installed very close to the equipment enclosure, avoiding the need to mount it externally. This addition to the component kit makes it easy to separate the enclosure to be purged from the user interface. The remote user interface can be mounted in a location that is more accessible to the user, while remaining in the hazardous area.

The 5000Q series is an exceptionally compact, economical and efficient purge and pressurization system, designed for both gas and dust atmospheres. It is economical because it allows users to save on cost and space thanks to a solution specially designed for ATEX zone 2/22 installations.

It is one of the simplest, most flexible and easiest-to-use purge and pressurization systems to date. The available programs allow the user to select a specific program to meet the different requirements of the application, with a pressure sensor that facilitates automatic purging and pressurization via a digital solenoid valve.
