Explosion proof grades BT4 and CT4

Explosion proof grades BT4 and CT4

The main differences between explosion-proof levels BT4 and CT4 are reflected in their explosion-proof capabilities, applicable gases, and protection levels，If the work environment involves high-risk gases such as acetylene and hydrogen, or requires a high level of protection, CT4 should be selected; If only conventional gases such as methane and ethane are processed and the temperature requirements are low, BT4 can be used.
