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-220 /SD- 600 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.
