Sistema de Purga e Pressurização tipo Z e Ex pzc Pepperl Fuchs 7500-01-AA-STD-UNV-PNO

Marca: Pepperl Fuchs

Modelo: 7500-01-AA-STD-UNV-PNO

Function

The 7500 series purge and pressurization system consists of a control unit, an enclosure protection vent, and a manual or automatic manifold.

The control unit’s menu-driven touch screen display makes it easy to select pre-programmed and user-selected variables.

The display has 4 LED indicators that allow users to determine system condition from a distance.

A digital manifold system such as the 5500-MAN-... can be used to make the 7500 a fully automatic system. Enclosure pressure and leakage

are monitored. If a loss in enclosure pressure occurs, the solenoid valve engages to restore the defined pressure settings and/or trigger a

pressure drop alarm.

The 7500 series system has NEC, CE Code, ATEX, CCC, and IECEx third-party certifications for Class I, II/Div. 2 Type Z and Zone 2/22 Ex Ppc.
