MLT 2 / BINOS
Protective Gas
Air or inert gas used for purging and
maintaining an overpressure and, if
required, dilution.
Pre-Purging
The pre-purging phase serves to remove any
combustible gas out of the analyzer's
enclosure prior to switching on the analyzer.
Pressurization modes
„Continuous Flow"
In EEx p „continuous flow mode" the
protective gas flows with higher rates
through the enclosure. Flow rates are
calculated to hold an overpressure of > 1
mbar compared to atmospheric.
Flammable Gas(es)
Gases and gas mixtures are assigned to be
flammable if they might become ignitable
when in a mixture with air.

ATEX Instruction Manual
Dilution
The continuous supply of a protective gas,
after purging, at such a rate that the
concentration of a flammable mixture inside
the pressurized enclosure is maintained at
a value outside the explosive limits except
in a dilution area.
„Leakage Compensation"
In EEx p „leakage compensation mode" just
as much protective gas is used to hold the
required overpressure compared to
atmospheric.
