What are the application areas for EX db IIC and EX db IIB explosion-proof lights?
What are the application areas for EX D IIC and EX D IIB explosion-proof lights?
  1. IIC explosion-proof lights are mainly used in production and storage areas for flammable and explosive gases such as hydrogen, ethane, and carbon dioxide. They are small in size but have a high explosive force. For highly hazardous flammable gases, choosing IIC-level lights is always a good choice.
  2. IIB explosion-proof lights are mainly used in petrochemical, ethylene, pharmaceutical, and paint spraying production and storage areas. IIB explosion-proof lights can withstand these common flammable gases.
  3. In summary: IIC explosion-proof lights cover the application areas of IIB explosion-proof lights, but IIC explosion-proof lights are more expensive than IIB explosion-proof lights. If you are unsure which to choose, please consult me.
