Electrical explosion protection class in the hydrogenation workshop
Thread Content
For procurement, only the explosion-proof tee of type EXDIIBT4 was bought. Will this work? Do I need to repurchase the EXDIICT6 tee?
In hazardous areas containing hydrogen, products of IIC explosion-proof category should be used as specified by the standards; no strict requirements are imposed on the temperature group, and any temperature group is acceptable.
According to the specifications, a CT1 level is sufficient for explosion protection in hydrogenation workshops; however, in practice, CT4 is the standard used for procurement； The CT6 is too high; it’s not necessary. The BT4 clearly does not meet the specifications. . .
