Section 10: 

maintenance schedule 

 

1.  Optical check of the silica gel for saturation

 

Check  

 The loading condition of the silica gel is to be determined by visual inspection of the 
adsorber. The colour orange indicates that the silica gel can still adsorb water and air is 
dehumidified. If the silica gel is completely saturated, the colour changes to green. 

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

   

Weekly 

Action 

 The silica gel is removed from the adsorber. New silica gel is refilled. With disposable 
adsorbers, the entire adsorber part is changed. 

 

2.  Check filter unit for impurities

 

Check 

 Remove

 

the lid from the adsorber part and remove the activated charcoal disc. Then 

empty the desiccant. The filter unit can then be removed. This must be checked for 
impurities and should be free of dirt for smooth operation.  

Cycle 

Half-yearly

 

Action

 

 

The filter unit is part of the spare parts package and should be replaced if there is 
contamination.

 

 

3.  Check prefilter disc for impurities

 

Check 

 The prefilter disc should be checked for impurities that may clog it and prevent free air 
entry. 

Cycle   

Half-yearly 

Action

   

Clean the prefilter disc with compressed air to remove dirt particles and dust.

 

 

4.  Check seals for wear

 

Check 

 

The

 seals and O-rings installed in the adsorber and in the valve part must be checked for 

their perfect condition. For this purpose, the flat seal in the cover, the O-rings of the filter 
unit, and the O-rings between the receiving and adsorber parts should be examined for 
brittleness. 

Cycle 

 

Yearly 

Action 

 In case of existing damage, the seals or O-rings should be replaced. These are part of the 
spare parts package.
