Hi,

>must have an Ex de certificate?

What are the details of the hazardous area the equipment is going >to be operating in?

What is the potentially explosive media? Gas? - What type of Gas?
Dust? - What type of dust?

What is the frequency of the presence of the potentially explosive media? is it there all the time, sometimes during operation, or infrequently?

If the potentially explosive media does occur - in what concentrations does it occur?

What potential heat sources are in the area?

Get a hazardous area evaluation by a CompEx trained engineer before moving forward.
If you do not do this then good luck to you - you'll need it.

Mr Sweeney.
 
The biggest advantage of Ex d protection is that you can install just about anything in that enclosure, from simple circuit breakers or transformers to complete plant control systems. These standard industry components are produced in high volumes and thus are less costly than the certified components.
