Application

Dilution extractive technology requires a con­stant low dew point clean air supply that
removes the concentrations well below the
lower detection limits (LDL) of the analyzers
used. This translates to low ppb concentra­tions in some cases.

With ever decreasing concentrations of mea­sured pollutants, an increased purity specifi­cation is required to maintain system repea­tability since simply changing dilution ratios
can cause serious complications

The air clean up supply BA-C has been deve­loped in order to achieve proper dilution air
for gas sample dilution probes (see data sheet
2-1.1.7), independent of gas cylinders.

The BA-C unit can also be used as a zero gas
generator when calibrating I.R.-analysers for
immission monitoring and for hydrocarbon
free burner air when measuring hydrocarbons
with a FID, FTIR and gas Chromatography also
need an ultra-pure reference as well as carrier
air supplies.

Description

The M&C-air clean up supply version BA-C has
been designed as compact, easy-to-use and
easy-to-service 19 inch and wall mounting
module.

With version BA-C compressed air is taken via
the rear-mounted air filter and is directed to
particle and condensate separation by means
of a high-performance filter (0.01 micron of
filter fineness) with an integrated, floating
condensate drainer.

There upon the compressed air is cleaned as
a result of low power catalytic oxidation by
means of a platinum/palladium catalyst of
hydrocarbon traces

(CnHm -> CO2 + 2H2O).

Drying the condensate-free compressed air
to <-100 °F dew point and removing NOx and
CO2 takes place in two mol sieve columns.
