A New Purge Solution for Large Enclosures: Bebco EPS® 6100 Series


Bebco EPS® 6100 Series Purge and Pressurization System
The automatic 6100 series system can purge enclosures that are larger than 12.2 m³ (450 ft³)

Pepperl+Fuchs will introduce the latest addition to its market-leading portfolio of purge and pressurization solutions at this year's SPS fair in Nuremberg, November 26 – 28, Hall 7A, Booth 330. The Bebco EPS® 6100 series was specially designed for use with large motors, drives, compressors, and enclosures in ATEX/IECEx Zone 1 hazardous locations. The largest purge and pressurization system available from Pepperl+Fuchs to this day, the automatic 6100 series system can purge enclosures that are larger than 12.2 m³ (450 ft³). This new system is ideally suited for applications in the chemical, petrochemical, and oil and gas industries.

Versatility for Demanding Applications

The 6100 system consists of a control unit, enclosure protection vent, low pressure sensor, and optional temperature sensors. The configurable control unit features temperature and pressure compensation, an extra output for control or alarm, two selectable intrinsically safe inputs for various actions, and up to three temperature sensor inputs that can monitor various points within a motor housing. The intrinsically safe user-interface can also be mounted in a separate enclosure near operating personnel for quick access and easy system monitoring.

To meet any application requirement in large enclosures, enclosure protection vents are available with five flow rates to choose from (up to 14,000 l/min). The intrinsically safe low pressure sensor provides an accurate enclosure pressure reading for safe operation in hazardous locations. The pressure sensor, which can measure internal pressure from 0 to 25 mbar, can be remotely located at the motor’s low pressure section for correct, safe motor pressure readings.
