Siemens Maxum II Service Manual

4.7.2 Purged Methanator
Although the purged/pressurized methanator assembly is installed in the detector
compartment, it is installed inside a protective cover that limits air passage. The interior of the
assembly is connected to the EC using a pipe which contains the electrical wiring for the
methanator. This pipe and the protective cover over the assembly effectively make the interior
assembly part of the pressurized EC. As described in AUTOHOTSPOT of this manual, this
higher pressure area prevents flammable vapors and gases from entering the methanator.

The purged methanator was replaced by the explosion-proof methanator described in the
