Order of spare parts
For constant operational readiness of the adsorber and thus of the hydraulic unit or transmission, make
sure that there is always a spare parts package or a spare adsorber part in stock.
The time to complete saturation of the activated carbon by the adsorption of oil mist and thus also the
service life of the adsorber depends on various factors:
- Number and duration of flow and loading intervals.
- Amount of oil particles and mists emitted.
Storage of adsorbers
All assemblies filled with desiccant are packed airtight. To avoid damage to the desiccant, it must also be
stored in dark and dry rooms at -10°C to +30°C.

Section 8: disposal
regeneration
In practice, the most common regeneration method used is temperature increase. When desorbing water
vapour from silica gel, the temperature shall be above 100°C. A regeneration temperature between
150°C and 175°C is recommended. However, it should be noted that a color indicator applied to the
silica gel will be damaged at these temperatures. Therefore a regeneration temperature of 120°C is
indicated for silica gel with colour indicator and should not exceed 140°C.
disposal
At the end of its useful life, the device must be disposed of in accordance with the relevant legal
regulations. Metal and plastic parts should be separated according to type and disposed of. The loaded
drying agent Silicagel Orange can be disposed of in household waste. Silicagel Orange is not classified
as a hazardous substance according to European Union legislation (Regulation EC No. 1272/2008).
According to the EC Directive (67/548/EEC or 1999/45/EC) it is not subject to labelling. Silicagel Orange
is not a hazardous substance for health or the environment.
The desiccant Silicagel Blue is mixed with cobalt(II) chloride hexahydrate and is classified as a
substance requiring labelling according to the EC Directive (1999/45/EC). This desiccant is one of the
substances hazardous to health and the environment. National regulations must be observed for
disposal.

Section 9: Risk and hazard analysis
1 Positive or negative pressure builds up in the system
1.1Valves are jammed / blocked
The functionality may be impaired by impurities.
→See maintenance plan point 5
1. 2Air flow rate too high
If the air flow rate is too high, overpressure or underpressure in the system can be
to build.
1.3Filter contaminated
The filter unit can be clogged by dirt particles.
→See maintenance plan point 2
1.4Prefilter disc contaminated
The prefilter disc can be clogged with dirt particles.
→See maintenance plan point 3
1.5 Oil film on the desiccant
Oil particles collect in the pores of the silica gel. Dirt particles can accumulate on the oil
film and thus hinder the supply or exhaust air.
→See maintenance plan point 1
2 Humid air flows into the system
2.1Porous seals
Moist air can flow into the adsorber at the porous points. This means that complete drying
is not possible and moist air enters the system.
→See maintenance plan point 4
2.2Saturated desiccant
If the desiccant is saturated, it cannot absorb any more moisture. This allows moist air to
enter the system.
→See maintenance plan point 1
2. 3Air flow rate too high
If the air flow rate is too high, the contact time between moist air and desiccant is too
short. This allows moist air to flow into the system.
2.4 Oil film on the desiccant
If oil particles get into the adsorber, the oil particles close the pores of the desiccant and
thus prevent the adsorption capability.
→See maintenance plan point 1
2.5 Ambient temperature too high
If the ambient temperature exceeds 80°C, the incoming ambient air is only dried to a
limited extent.
3 Adsorber housing is damaged
3.1Material resistance
When selecting an adsorber, the ambient and operating conditions should be taken into
account.
→See maintenance plan point 6
3.2Vibrations of the system
Strong vibrations of the system can damage the adsorber.
→See maintenance plan point 6

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.
Action:
The silica gel is removed from the adsorber. New silica gel is refilled. With
disposable adsorbers, the entire adsorber part is changed.
Proceed as described in "Part 6 Maintenance".
Weekly
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.
Action:
The filter unit is part of the spare parts package and should be replaced if
there is contamination.
Proceed as described in "Part 6 Maintenance".
Half-yearly
3. Check prefilter disc for impurities
Check:
The prefilter disc should be checked for impurities that may clog it and
prevent free air entry.
Action:
Clean the prefilter disc with compressed air to remove dirt particles and
dust.
Half-yearly
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.
Action:In
case of existing damage, the seals or O-rings should be replaced. These
are part of the spare parts package.
Proceed as described in "Part 6 Maintenance".
Yearly

5. Check valves for jamming
Check:
The valve part must be visually inspected for impurities and damage. In
order to ensure long-term functionality, the valves of the valve section
should be checked. To do this, remove the adsorber part from the valve
part and check the functionality of the valves.
Measure:
If the valves do not open and close, replace the valve part with a new one
to ensure full functionality.
Biennial
6. Optical control of the adsorber
Check:
The adsorber (valve part and adsorber part) must be visually checked for
damage. Damage can occur due to various environmental or operating
conditions.
Action:
If the adsorber is damaged, replace the damaged part to ensure full
functionality.
Weekly
7. Replacing wear parts
Check:
The wear parts of the adsorber and the valve part must be checked for
their condition.
Measure:
Regardless of the result of the test, it is recommended to replace the
wearing parts by using the spare parts package or a new adsorber part to
ensure smooth operation.
