A large analysis equipment manufacturer based in the USA wants to design a standard solution for its portfolio that allows end customers to measure the purity of hydrogen directly at refueling facilities. To achieve this, the company’s own hydrogen analysis equipment—which did not have Ex certification—needed to be used in hazardous areas. Pepperl+Fuchs was commissioned to provide a suitable type of protection for the components to enable the solution to be used in Zone 1/21 and Zone 2/22 environments.
The three necessary analysis devices are housed in an enclosure equipped with a purge and pressurization system. In addition, many other useful features are added. For example, special piping is laid to the analyzers, door handles are installed, and special air holes are drilled in specific locations to ensure that the purging process clears all areas of the explosive atmosphere. To compensate the high power dissipation and to keep the heat development under control, an air conditioner is installed on the outside of the enclosure.
Bebco EPS® purge and pressurization systems are used in hazardous areas in the process automation industry. Continuous monitoring of conditions inside the enclosure provides reliable explosion protection for a wide variety of applications. The comprehensive portfolio of globally certified purge and pressurization systems makes it easy to specify and select the right solution for your process.
