This company’s 6000 Type X/Ex pxb purge-and-pressurization system, used for explosion protection in electrical enclosures, has been updated with a high-current electronic processing control unit (EPCU). The latest enhancement introduces an upgraded contact rating for the 6000 EPCU’s enclosure contacts. Previously rated at 8 A, the two enclosure contacts on the newest 6000 Series now support up to 12 A per contact. This increase allows higher-current applications to be supported directly, reducing or eliminating the need for additional high-current contacts or breakers housed in explosion-proof enclosures and offering a significant project cost savings. The increased capacity allows the control unit to switch enclosure power directly within the system for a broader range of applications. As a result, higher-load applications, such as gas-analyzer systems or enclosures with integrated heating, can often be implemented without the need for additional Ex-rated contactors or breakers, resulting in cost savings. This supplement to the popular 6000 Series purge offering resulted from customer and sales feedback. Designed as the complete solution for Division 1 or Zone 1/21 hazardous operations to non-hazardous areas, the stainless steel unit contains the controller, pneumatics, electrical I/O, and programming interface in one sleek, fully automatic package. — Pepperl+Fuchs, Mannheim, Germany
