Aluminum (EJB)

The EJB series comprises of 22 sizes of Ex d IIB+H2 and Ex tb certified enclosures made from copper-free aluminum. This material provides high corrosion resistance, and offers the most cost-efficient option for many industries including offshore and marine applications. The EJB enclosures have an external flange to provide an appropriate IIB flame path which ensures the maximum internal space for installation of components and instrumentation.

A comprehensive choice of certified operator elements such as switches and pushbuttons as well as monitoring devices allows the tailor-made design of control stations. In conjunction with non-Ex devices specified by the customer, from terminals to transformers or PLCs, which will be integrated into the enclosures, the Pepperl+Fuchs project engineers will design elaborate control and distribution panels as efficient solutions to any requirements.

Contact your Pepperl+Fuchs representative for a customized configuration of your EJB control solution and get advice on all available options for built-in instrumentation.
