FC LCU Control Units Ex d IIC: Aluminum Enclosures for the Most Dangerous Gases

FC LCU Ex d IIC: Flameproof Aluminum Control Stations for IIC Gas Groups

FC LCU (Flameproof Control Units) series from Pepperl+Fuchs is a specialized solution for local control in environments containing the most dangerous explosive gases, such as Hydrogen and Acetylene. These control stations provide the highest level of protection — Ex d IIC.

The use of a Flameproof Enclosure (Ex d) combined with a lightweight and durable aluminum construction makes the FC LCU an ideal choice for the chemical, oil and gas, and pharmaceutical industries where maximum safety is paramount.

Maximum Protection: Ex d and Group IIC

The Ex d IIC protection is the highest standard, ensuring safety in the most critical zones:

• Group IIC (Hydrogen and Acetylene): This classification means the enclosure is designed to prevent the propagation of an explosion from gases that have the lowest Minimum Ignition Energy (MIE), including IIC. This is a mandatory requirement for operation in specific manufacturing processes.

• Ex d Principle (Containment): The aluminum enclosure is constructed to reliably withstand an internal explosion without transferring heat or sparks to the surrounding atmosphere.

• Material — Aluminum: The use of aluminum ensures an excellent strength-to-weight ratio. This simplifies installation while maintaining the necessary enclosure integrity for Ex d protection.

Integrated Functional Capabilities

FC LCU stations are supplied as ready-to-use control stations that can be individually equipped with:

• Control Elements: START/STOP pushbuttons, switches, lockable Emergency Stop (E-Stop) buttons.

• Indication: Pilot lights that use safe components and provide visual monitoring.

• Flexibility: The modular design allows for the creation of posts with single, dual, or multiple functional sections according to local control requirements.

Why Choose FC LCU Ex d IIC?

These control stations are an investment in safety that eliminates the risk of ignition of the most explosive gas mixtures, thanks to ATEX and IECEx certification to the highest IIC group.
