Intended use

The intended use of the Pressure control panel SE45/55/125 is the expansion of a gas from a gas source and the distribution of the gas with adjustable outlet pressure.

The Pressure control panel SE40 and SE45 is fitted with a gas shut-off valve instead of a pressure regulator. This means that the pressure is not regulated. Instead the gas line is shut off and re-opened. This must be taken into consideration when reading the remainder of the text.

Pressure control panels of type SE45/55/125 are suitable for flammable gases, non-flammable gases, oxygen and additionally also for use with corrosive and toxic gases and gas mixtures up to gas quality 6.0.

Purge gas purging is recommended when using corrosive or toxic gases.

The permissible gas types and pressure ranges are each specified on the label (see "Identification / label").

The equipment versions of the Pressure control panels without electrical components may be used in an explosion hazard zone as they do not have separate ignition sources (ignition hazard assessment according to DIN EN ISO 80079-36).

Pressure control panels with electrical components that are suitable for use in an explosion hazard zone are marked on the label according to EU Directive 2014/34/EU.

To be able to use the Pressure control panels as intended, all persons working with them must comply with the specifications of the relevant user manual.

The area in which hazards can occur when used as intended is the area around the Pressure control panels. The danger zone changes depending on the system status and use.
