FW LCU Ex d IIB Control Units: Reliable Control in Aluminum Enclosures

FW LCU Ex d IIB: Flameproof Aluminum Control Stations for IIB Gas Groups

The FW LCU (Flameproof Control Units) series from Pepperl+Fuchs represents highly durable control stations designed for safe operation in hazardous areas (Zone 1, Zone 2) involving Group IIB gases. These devices are an ideal solution for local equipment control and process monitoring in chemical plants, refineries, and facilities with gases such as Ethylene.

Utilizing the Flameproof Enclosure (Ex d) method and a sturdy aluminum construction, the FW LCU ensures maximum functionality and longevity.

Robust Ex d IIB Protection

The Ex d IIB protection provides a high level of safety for a wide range of industrial gases:

• Group IIB (Ethylene and Others): This key classification confirms that the enclosure is capable of preventing the propagation of an explosion from gases in this group. This makes the FW LCU a versatile solution for most industrial applications.

• Ex d Principle: The aluminum enclosure is constructed to contain an internal explosion and cool the combustion gases before they exit, ensuring the external explosive atmosphere is not ignited.

• Durability: The design provides a high degree of protection against dust and moisture (IP66), making the posts suitable for harsh field conditions.

Construction and Modularity

The FW LCU stations leverage the benefits of aluminum casting:

• Durable Aluminum Housing: Aluminum provides the necessary mechanical strength for the Ex d method while remaining lighter than steel counterparts, simplifying transport and installation.

• Ready-to-Use: The stations are supplied as fully assembled and certified control stations, including the necessary control and indication elements according to individual requirements.

• Flexible Outfitting: Capability to integrate pushbuttons, switches, indicators, and terminal connections in various configurations.
