SECTION 1
1.4.5 Transport
After the adsorption dryer has been delivered, it must be checked for damage that may
have occurred during transport. If necessary, the Transport company must be informed
to register the damage.
* Advices
For transport within the company, only the skid of the adsorption dryers
SD-820 – SD-1710 may be used.
1.4.6 Storage
If the adsorption dryer is to be stored for a longer period of time, its place of storage
must be dry and free of dust. There has to be a min. ambient temp. of +1°C (33°F).
1.4.7 Use of a pre and after filter
In order to prevent droplets of condensate, oil and dirt from getting into the desiccant,
a pre-filter is installed in front of the adsorption dryer, since an oil film on the desiccant
reduces the drying capacity and the dewpoint. In order to prevent breakdowns in
downstream consumers caused by material that has been abraded from the desiccant
bed, an after-filter is mounted behind the adsorption dryer. Since no condensate
accumulates in the after-filter, this filter is always equipped with a manual valve.
Both filters are equipped with a differential pressure gauge (standard) as this ensures
an indirect display of the degree of contamination of the filter elements.
