1.2
Description of the pressure control panels of the BM and BE series
Spectron pressure control panels are available in BM and BE versions.
BM pressure control panels are suitable for combustible gases, non-combustible gases and oxygen up to
a purity grade of 6.0. BE pressure control panels are suitable, in addition, for use with corrosive gases.
In addition, there is a distinction between pressure control panels with single-stage pressure relief from the
inlet pressure to the desired outlet pressure (type code: 55) and two-stage pressure relief (type code: 56).
While two-stage pressure relief ensures an extremely constant outlet pressure throughout the entire inlet
pressure range (from "full" gas cylinder to almost "empty" gas cylinder), with single-stage pressure relief the
outlet pressure can vary within a certain range.
