What are the different uses of EX D IIC and EX D IIB?
IIC explosion-proof lamps are mainly used in the production and storage of flammable and explosive gases such as hydrogen, ethane, and carbon dioxide. They are small in size, have high explosive power, and pose a high risk to flammable gases. Choosing IIC grade lamps is definitely not wrong.
IIB explosion-proof lamps are mainly used in production and storage places such as petrochemical, ethylene, pharmaceutical, paint spraying, etc. IIB explosion-proof lamps can resist these common flammable gases.
3. Summary: The use of IIC explosion-proof lamps covers the use of IIB explosion-proof lamps, and the cost of IIC explosion-proof lamps is higher than that of IIB explosion-proof lamps. If you don't choose to consult me, then come and consult me
