In the analysis cabin, the chromatography carrier gas is hydrogen – what is the explosion-proof rating of the air conditioning? Distance?
It's better to describe the problem clearly and accurately so that others can help you.
Is the poster asking about the explosion-proof category of hydrogen? IIC T!
Explosion protection rating: ExdIIBT4-ExdIICT6. The temperature depends on the temperature in your cabin; in the north, heating may be available in winter!
Don’t just focus on the fact that it’s hydrogen; its explosion-proof rating is relatively high. First, let’s see which district he is in It seems that in Zone 2, you need to consider various factors as a whole.
It mainly depends on whether the cabin is located in Zone 1 or Zone 2. The design institute will usually specify the explosion-proof rating for the electrical equipment used in the cabin; generally, ExdIIBT4 is used for Zone 2, while ExdIICT4 is used for Zone 1. As for air conditioners, there isn’t much difference in price between IIB and IIC ratings
The heating isn’t working, and the temperature can’t be controlled. The air conditioner is still more useful
This explosion protection rating is definitely sufficient, ExdIICT6; even experts can find no flaws with it
