The 5500 Series purge and pressurization system, part of the Bebco EPS line of proven purge solutions from Pepperl+Fuchs, brings a modern approach to the safe and economical Ex p protection method. This Type Z / Ex pz purge system delivers a fully automatic solution in a compact, 316L stainless steel design. This, combined with other best-in-class features, makes it a top choice for applications in hazardous environments, and offers a safe and economical approach to installing electrical equipment in demanding applications.
Features and benefits
The 5500 is an all-in-one solution for Div. 2 / Zone 2 applications. Its key features include:
- A compact control unit with menu-driven programming. This unit can be internally or externally mounted and provides an easy-to-use interface, enabling users to select from a list of custom programs that fits the exact needs of the application. Users can also define temperature ranges to control and alarm critical temperatures within the purge enclosure. When a critical temperature is reached, a solenoid displaces air or initiates heating or cooling functions within the enclosure. If a drop in pressure is detected, the unit automatically compensates to ensure that pressure within the enclosure does not fall below the minimum value.
- EPV vent. The EPV-5500 vent functions as a pressure relief device, enabling the purge gas to exit the enclosure while providing a seal when the enclosure is pressurized and operating. The vent’s mechanical construction supports universal mounting to easily fit in cabinet or machine housing designs.
- Third-party approvals. The 5500 Series has third-party worldwide approvals for NEC, CEC, IEC Standards, and CE Directives for Class I,II,III/ Division 2 and Zone 2/22 environments.
These features help to create a safe area inside a standard enclosure, allowing general-purpose equipment to be used in hazardous areas.
