As we all know by now, working under Zone Classifications is a bit of a challenge for those of us who have been using the Division System. We not only have to retrain ourselves to the new Ex methodology, but we now have to contend with the regulations of the EU and the ATEX Directive if we ship anything to the EU member countries. As cumbersome as this may seem to be, the Zone system provides you and your customer with an overall savings that the Division System could not.
The advantages of the Zone system far outweigh the Division in that the enclosures are lighter and smaller which lessens mounting problems. There is less maintenance time and they are aesthetically more attractive.
This is where we, at Rose+Bopla, can help. Rose+Bopla carries over 130 Ex/ATEX enclosures, up to and including hand held enclosures. They are available in carbon-loaded, fiberglass-reinforced polyester (Polyglas®), aluminum and stainless steel... complete with custom
terminal configurations. Rose+Bopla enclosures are manufactured to close tolerances and our workmanship is unsurpassed.

We provide a complete range of added value secondary services including drilling, tapping, machining, painting, powder-coating, engraving, silk-screening, milling,
irriditing, chromating and anodizing.The global economy has changed, allowing world trade to expand greatly. This, in short, creates a larger market for all our products. This also means that we, who work in and around hazardous locations (hazloc), are all required to familiarize ourselves with many more codes in relation to our fields of practice. In the electric/electronics field we must adhere to ATEX from the European Norm (EN),
the Canadian Standards Association (CSA), the National Electric Code (NEC), and others from several countries. The majority of the countries specify that
components in the electric/electronics field must be tested and approved by that country’s independent testing agencies. Those could be UL (United States), PTB
(Germany), CEPEL (Brazil), SIPAI (China) and many more. Although this may seem to cause more paper work
than we really need, the service provided by these agencies saves many dollars in equipment from being destroyed |

(due to hazardous location
accidents), not to mention the human factor. Rose+Bopla enclosures have been tested and approved in most of these countries. Rose+Bopla has offices in forty-two countries. Rose+Bopla will provide the utmost care in preparing the enclosures
for your use, in the U.S. or any other country; after all, we’ve been serving the European community for quite a while.
NOTE: In reference to the European community and the codes that influence the electric/electrical design there, one should take notice of Article 505 - Class I, Zone 0, 1, and 2 Locations in the National Electric Code 2005. Article 505 is the new article that allows for the zone classifications and thus the use of “Increased Safety” type design. Within that article, as in several other articles of the NEC, references are made to other publications from other agencies. In article 505, there is a direct correlation to the IEC 79. In reference to Article 505-4(f) “Increased Safety” “e”, the NEC states that for information see the ISA S12.16.01-1996 and IEC 97-7. |
