Pressure range of the system
The adsorber should not be exposed to positive or negative pressure above 1.0 bar, otherwise the
housing may be damaged.
Thread of the adsorber and accessories is damaged
When mounting the adsorber on the system, the threads must be
slightly moistened with oil. Failure to lubricate the threads can
lead to the thread rubbing and is not a reason for complaint.
Section 10: Maintenance plan
1. Check seals for wear
Check The flat gaskets and O-rings installed on the adsorber must be checked for perfect
condition. For this purpose the seals in the lid, on the filter and on the connection should
be checked for brittleness.
Cycle Half-yearly
Measures In case of existing damage, a new spare parts kit or a new adsorber should be used.
2. Check filter unit for impurities
Check Take off the lid and remove the activated carbon disc. Then empty the desiccant. The filter
unit can then be removed. This should be checked for contamination and should be free of
dirt for smooth operation.
Cycle Half-yearly
Measures The filter element is part of the spare parts kit and should be replaced if it is contaminated.
3. Visual inspection of the silica gel
Check The loading condition of the silica gel must be determined by visual inspection of the
adsorber. The colour orange indicates that the silica gel can still adsorb water and air is
dehumidified. When the silica gel is completely saturated, the colour changes to green or
colourless.
If there are oil particles on the silica gel, these close the pores and the adsorption capacity
is reduced. This causes the silica gel to discolour more slowly and unevenly.
Cycle Half-yearly
