TWINSBURG, OH – Pepperl+Fuchs’ popular Bebco EPS® 6000 Series Type X / Ex px Purge Pressurization System is now available with updated firmware and new hardware options that deliver application-specific operational enhancements that make implementing purge systems easier and less expensive than ever before.
Additionally, automatic temperature control is now possible with the 6000 Series Temperature Hub and Temperature Sensor, enabling users to sense the temperature of various surfaces inside or outside the enclosure. And with its updated programming menu, the 6000 series control unit allows users to set averaging or maximum temperature, and can be used to turn on the solenoid valve on the manifold, activate the auxiliary relays to a cool or heat the enclosure, or warn of temperature problems.
Overview of the new features:
• Automatic pressure control after purging
• New intrinsically safe temperature hub and sensors modules
• Additional system feedback and alarms
• I.S. inputs can be inverted for normally closed inputs
• Addition of Spanish, French and German programming menus for the global markets
The 6000 series comes with all Bebco family system features as standard, is user-configurable to satisfy particular applications, and can be used with enclosures up to 250 cu. ft. (7.1 cu.m.) of volume. Both the control unit and vent are universally mountable for all enclosure sizes. It is also universal certified to all applicable updated standards for both Gas and Dust hazardous atmospheres. It is IECEx, cULus and ATEX directive certified, and complies with Safety Integrity Level IEC 61508 SIL 2.
The 6000 series is a complete purging system that contains the controller, pneumatic, electrical I/O and programming interface housed in a durable type 4X, IP66-rated housing. Additionally, all exposed parts are 316L (UNS31603) stainless steel, making the 6000 series well suited for use in offshore, refinery and pharmaceutical applications where corrosive or potentially explosive environments exist. For users who wish to custom fit the new purge/pressurization system to their enclosure, the 6000 series is also available in a cost effective component-kit modular version. Universal mounting options facilitate easy integration into existing or customized systems, and enable the unit to be mounted to the enclosure in any vertical or horizontal orientation. The unit’s “smart vent” works on all enclosure sizes, and includes a gravity-free flapper and rotatable vent cap with spark arrestor that allows the vent to also be mounted in any orientation – even inside the enclosure.
A user-friendly interface with back-lit LCD and highly visible LEDs enables easy programming and operation to meet specific application requirements. This also eliminates the need for analog pressure gauges, as the screen displays information such as flow, pressure and system status, with pressure and flow feedback provided to the control unit by the vent. The interface also provides diagnostics for reviewing start-up and operating parameters, and can be rotated to any orientation required by the application. Additionally, the manifold has an automatic purging and pressurization feature that offers considerable cost savings on gas in applications using non-atmospheric air and allows the system to automatically purge and pressurize without an operator present.
Purge and pressurization protection is suitable for many applications, and is one of the most flexible Ex protection solutions. Bebco EPS systems from Pepperl+Fuchs provide the means to operate general purpose equipment in classified areas, or in environments that are highly corrosive or dusty. The principle behind purge and pressurization systems is to prevent a corrosive, dusty or potentially explosive atmosphere from penetrating a closed protective housing using a standard overpressure technology. These systems control and monitor compressed instrument air or inert gas through the protected enclosure(s) so as to remove and prevent the accumulation of flammable gas, vapors or dust, thus making the inside of the pressurized enclosure safe.
