Hydrogen Gas Connections
On the Desiccant cartridge holder, there are two ¼” compression fittings. The fitting on
the lower block is the inlet and receives gas from the hydrogen generator. The fitting on
the top block is the product out and is to be connected to the process or hydrogen
distribution system, see Figure 3.
Figure 3 Desiccant Holder Connections
If the GC4800 system is to be used in conjunction with a crossover manifold or any sort
of back-up supply for uninterrupted gas flow, a ASME stamped pressure relief valve set
to no greater than 275 psig must be installed in the line and properly vented to protect
against an over pressurization of the desiccant cartridge holder.
The HOGEN hydrogen generator has its own integrated ASME stamped pressure
relief device installed.
