A next-generation purge and pressurization system

By Chemical Engineering |

Pepperl+Fuchs

Designed for Class I or II/Div. 2 and Zone 2/22 locations, the 7500 series Ex pzc/Type Z purge and pressurization system purges a common enclosure of hazardous gas or dust to maintain positive pressure. With operations in fully automatic or manual modes, it effectively reduces the classification within the protected enclosure to a non-hazardous area. The 7500 carries ATEX and IECEx certifications and is UL listed. It operates within a very small footprint of 5.8 in. × 3.8 in. × 1.9 in. The 7500 Series includes intelligent automatic monitoring and control of enclosure pressure with dilution and continuous-flow functionality. The system makes automatic adjustments and provides an alarm output for reliable protection. It is designed in marine-grade chromate aluminum, making it rugged enough to withstand harsh conditions. — Pepperl+Fuchs GmbH, Mannheim, Germany
