Recognizing and Mitigating Combustible Dust Hazards

Posted by Ryan Brownlee on Mon, Oct 15, 2018

Combustible Dusts are a known hazard in a number of industrial fields. Recognizing dust as a potential hazard and taking the steps to mitigate the risks present are critical to the safety of your facility. The recently updated NFPA® 652: Standard on the Fundamentals of Combustible Dust is a useful resource for addressing combustible dust hazards and conducting a dust hazard analysis (DHA) within your facility.

Bebco EPS® 4000 Series Purge and Pressurization System

Posted by Andre Clayton on Thu, Oct 04, 2018

The Pepperl+Fuchs Bebco EPS® 4000 series Type X purge and pressurization system, which is rated for Class I, Division 1 to non-hazardous area applications and UL, cUL, CE and EX, classified, is no longer in production. This system has been replaced by our 6000 series Type X system, an automatic purge and pressurization system that reduces the classification within an enclosure from Zone 1 and 21 to a non-hazardous area.

Its IP66-rated stainless steel casing conveniently contains the pneumatics, controller, electrical I/O, and programming interface. An easily accessible LCD screen allows easy programming and displays the pressure, flow, and system status.

The 6000 system is commonly used in applications that involve basic electronics, electrical equipment, motors, and switchgear. Bebco EPS products meet the demands of rack-mounted instrumentation, video displays, programmable controllers, computers, printers, recorders, measurement, gas analyzers, and calibration equipment.

How to Calculate the Maximum Enclosure Size for an Ex pz Purge and Pressurization System

Posted by Brent Dean on Fri, Sep 09, 2016

The maximum size of an Ex pz purge enclosure is determined by the pressure and flow that can be reached inside the enclosure. For this 'how to' post, I'll use our 5500 series purge system for the examples.

Depending on your application, there are three vent options that you can use with your system. The EPV-5500-…-01, EPV-5500-…-02, or EPV-5500-…-03. Each vent opens at a different back pressure and has different flow rates, which are listed below.
