Recently we installed an instrument air compressor at our plant, the compressor is of type GA37+ and having a dryer Donalson Ultrafilters. The package was left idle for more than one year before being started where the humidity & moisture content is very high at this time of the year.
An alarm was observed during start-up indicating high dew point where the moisture analyser reads -33 C. we don't know whether th problem comes from the drayer prefilter or the desiccant of the adsorbers.
appreciate if any one can advise,,,,,,
