Ed. Note: In this video Thomas Kasten, Product Marketing Manager for Systems+Solutions, explains the features of the explosion protection type flameproof Ex d. With Ex d, potential ignition sources are contained inside a sturdy enclosure, so the surrounding environment is never in danger. Just about anything can be installed in this type of enclosure. However, the cost of medium to large Ex d enclosures can be very expensive. The solution: a combination of an Ex de enclosure with an Ex e termination and control unit. This helps eliminate the need for a large Ex d enclosure, which drastically cuts down the cost of the solution. It also saves time and money during maintenance, installation, and any future modifications to system. The other benefits of these Ex de solutions are demonstrated in the video.
