Types of Explosion proof Certificates
includeOur company has deep cooperation with national explosion-proof laboratories to provide explosion-proof certificates for electrical equipment such as explosion-proof type (d), increased safety type (e), intrinsic safety type (i), positive pressure type (p), n-type (n), oil filled type (o), sand filled type (q), and sealed type (m). The certification is fast and affordable, and we help customers handle all explosion-proof related matters from product design to market sales. Our services cover various fields such as petroleum, chemical, coal mining, metallurgy, transportation, and military industry. Welcome to call us for further discussion.
