Maintenance

Adsorbers of the VV-D series are not serviced, but completely replaced.

Maintenance

Maintenance

0% -> 100%

If the colour of the silica gel has completely changed according to the colour indicator used, the adsorber must be replaced.

    1. Unscrew the adsorber from the system and dispose of it.

    2. Screw a new adsorber onto the system.

 


Spare parts and storage

If the disposable adsorber is completely saturated, it must be replaced by a new adsorber.

Adsorber VV-D      Adsorber
- Silica gel
- Activated carbon
- Filter element
- Seal

Pre-assembled in the housing and packed airtight.

 

Order of spare parts

For a constant operational readiness of the adsorber and thus of the plant, make sure that a replacement adsorber is always in stock.
The time until the complete colour change and thus the service life of the adsorber depends on various factors:

  • Number and duration of flow and loading intervals.
  • Air flow volume and flow velocity, relative humidity of ambient air.
  • Temperature of the ambient air and the medium to be ventilated.

 

Storage of adsorbers

All articles filled with desiccant are packed airtight. In order to avoid damage to the desiccant, they must also be stored in dark and dry rooms at -10°C to +30°C.

 


Disposal

At the end of its useful life, the device must be disposed of in accordance with the relevant legal regulations.
The fully loaded adsorber can be disposed of in household waste.
Silicagel Orange is not classified as a hazardous substance under European Union legislation (Regulation EC No 1272/2008). It is not subject to compulsory labelling according to EC Directive (67/548/EEC or 1999/45/EC). Silicagel Orange is not classified as a substance hazardous to health or the environment.

 


Risk and hazard analysis

1. Moist air flows into the system
Porous seals
Moist air can flow into the adsorber or into the plant at the porous points. As a result, complete drying is not possible and moist air enters the system.

Saturated drying agent
When the desiccant is saturated, it can no longer absorb moisture. This allows moist air to enter the system.

Air 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.

Oil on the drying agent
If too many oil particles enter the adsorber, the oil particles close the pores of the desiccant and thus prevent adsorption.

Ambient temperature too high
If the ambient temperature exceeds 80°C, the binding forces in the desiccant decrease. As a result, the incoming ambient air is only dried to a limited extent.

2. Positive or negative pressure builds up in the system
Air flow rate too high
Too high an air flow rate can cause over- or underpressure in the system.

Contaminated filter element
The filter unit can be clogged by dirt particles and can therefore build up pressure in the system.

Oil on the drying agent
If oil particles get into the adsorber, the spaces in the fill can be filled with oil and the fill will stick together. This can cause pressure to build up in the system.

3. Adsorber is damaged
Material resistance
When selecting the adsorber, the ambient and operating conditions should be considered. An aggressive environment or liquid in the container can damage the adsorber.

Temperature range
The ambient and operating temperatures should not exceed or fall below the specified range, otherwise the adsorber may be damaged.

Improper handling
Incorrect or improper handling can damage the adsorber. Please pay attention to the recommended installation.

Strong vibrations
Strong vibrations of the plant can damage the adsorber.

Pressure range of the system
The adsorber should not be exposed to a positive or negative pressure above 0.5 bar, otherwise the housing may be damaged.

Cleaning of the adsorber
For external cleaning of the adsorber, the use of a mild soap in combination with water is recommended. The use of brake cleaner will damage the adsorber and is no reason for complaint.

 


Maintenance plan

1. Check seals for wear

Check    The O-ring installed on the adsorber must be checked for perfect condition. For this purpose, the seal at the connection should be checked for brittleness.
Cycle    Half-yearly
Measures    In case of existing damage, a new O-ring or a new adsorber should be used.

2. 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. If 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
Measures    If the silica gel is loaded or damaged by oil, a new adsorber with fresh silica gel should be used.

3. Visual inspection of the adsorber

Check    The adsorber, including the connection, must be visually checked for damage. Damage can occur due to various environmental or operating conditions.
Cycle    Yearly
Measures    If the adsorber is damaged, it must be completely replaced to ensure full functionality.

Disposal

Regeneration

In practice, the most common regeneration method used is the temperature increase. When desorbing water vapour from silica gel, the temperature must be above 100°C. For silica gel with colour indicators, a regeneration temperature of 120°C should be maintained in order not to damage the colour indicator applied.
It is nevertheless recommended to use fresh silica gel.

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 and disposed of separately. The loaded desiccant Silicagel Orange can be disposed of in household waste.
Silicagel Orange is not classified as a hazardous substance under European Union legislation (Regulation EC No 1272/2008). It is not subject to compulsory labelling according to EC Directive (67/548/EEC or 1999/45/EC). Silicagel Orange is not classified as a substance hazardous to health or the environment.

Order of spare parts

For a constant operational readiness of the adsorber and thus of the plant, make sure that a replacement adsorber is always in stock.
The time until the activated carbon is fully loaded and the colour change from colourless to brown and thus the service life of the adsorber depends on various factors:

  • Number and duration of flow and loading intervals.
  • Quantity of oil particles and mists emitted.

 

Storage of adsorbers

All articles filled with activated carbon are packed airtight. To avoid damage to the activated carbon, it must be stored in dark and dry rooms at -10°C to +30°C.

 


Disposal

At the end of its useful life, the device must be disposed of in accordance with the relevant legal regulations.
The loaded activated carbon must be disposed of according to the absorbed substance (e.g. hydraulic or gear oil).
Activated carbon and silica gel are not classified as hazardous substances under European Union legislation (Regulation EC No 1272/2008). It is not subject to compulsory labelling according to EC Directive (67/548/EEC or 1999/45/EC). Activated carbon and silica gel are not classified as substances hazardous to health or the environment.

 


Risk and hazard analysis

1. Oil flows out of the plant
Porous seals
Air containing oil can flow from the adsorber into the environment at the porous points. This means that no protection against oil mist in the air is possible.

Saturated activated carbon
When the activated carbon is saturated, it can no longer absorb oil. As a result, oil particles from the system are released into the air.

Air flow rate too high

2. Positive or negative pressure builds up in the system
Air flow rate too high
Too high an air flow rate can cause over- or underpressure in the system.

Contaminated filter element
The filter unit can be clogged by dirt particles and can therefore build up pressure in the system.

Activated carbon saturated
Once the activated carbon is completely saturated, oil can deposit and clog the adsorber.

3. Adsorber is damaged
Material resistance
When selecting the adsorber, the ambient and operating conditions should be considered. An aggressive environment or liquid in the container can damage the adsorber.

Temperature range
The ambient and operating temperatures should not exceed or fall below the specified range, otherwise the adsorber may be damaged.

Improper handling
Incorrect or improper handling can damage the adsorber. The recommended installation must be observed.

Strong vibrations
Strong vibrations of the plant can damage the adsorber.

Pressure range of the system
The adsorber should not be exposed to a positive or negative pressure above 0.5 bar, otherwise the housing may be damaged.

Cycle    Half-yearly
Measures    With loaded activated carbon, a new adsorber with fresh activated carbon should be used.

3. Visual inspection of the adsorber

Check    The adsorber, including the connection, must be visually checked for damage. Damage can occur due to various environmental or operating conditions.

Assembly and commissioning

Assembly and commissioning

1. If it is a metal connection, the thread must be slightly oiled before screwing in.

2. Screw the adsorber together with the valve section (ready for installation) onto the system.
If the valve part has been unscrewed, make sure that the O-rings (highlighted blue in the picture) are in the correct position.
The outer O-ring must be in the groove of the valve part and the inner O-ring in the groove below the thread.
Screw tightly by hand.
Adsorbers of the series VV-DV 1M, or VV-DV 1L do not have a valve part, since the valves are already installed in the cartridge.

Assembly and commissioning Assembly and commissioning

 


Maintenance

In adsorbers of the VV-DV series, the cartridge is replaced by a new one after a full load.

Maintenance

Maintenance

0% -> 100%

When the colour of the silica gel has completely changed according to the colour indicator used, the cartridge must be replaced.

If it is an adsorber of the VV-DV 1M or VV-DV 1L series, the entire adsorber is replaced by a new one.

Maintenance     

    1. Unscrew the adsorber section (cartridge) from the valve section and dispose of

    2. Remove the protective plug of the new cartridge.

    3. Make sure that the O-ring of the valve part sits in the groove and then screw the new cartridge tightly onto the valve part.

 

 

 


Spare parts and storage

If the adsorber is completely saturated, the cartridge must be replaced with a new one.

Adsorbers of the VV-DV 1M and VV-DV 1L series are excluded. These are replaced by a new adsorber.

Order of spare parts

For a constant operational readiness of the adsorber and thus of the plant, make sure that a replacement cartridge or a replacement adsorber is always in stock.
The time until the complete colour change and thus the service life of the adsorber depends on various factors:

  • Number and duration of flow and loading intervals.
  • Air flow volume and flow velocity, relative humidity of ambient air.
  • Temperature of the ambient air and the medium to be ventilated.

 

Storage of adsorbers

All articles filled with desiccant are packed airtight. To avoid damage to the desiccant, they must be stored in dark and dry rooms at -10°C to +30°C.

 


Disposal

At the end of its useful life, the device must be disposed of in accordance with the relevant legal regulations.
The fully loaded cartridge can be disposed of in household waste.
This also applies to the entire adsorber.
Silicagel Orange is not classified as a hazardous substance under European Union legislation (Regulation EC No 1272/2008). It is not subject to compulsory labelling according to EC Directive (67/548/EEC or 1999/45/EC). Silicagel Orange is not classified as a substance hazardous to health or the environment.

 


Risk and hazard analysis

1. Moist air flows into the system
Porous seals
Moist air can flow into the adsorber or into the plant at the porous points. This means that complete drying is not possible and moist air enters the system.

Cartridge or O-ring does not fit properly on the valve part
If the cartridge is not seated firmly enough (well hand tight) on the valve part, or if the outer O-ring of the valve part is not seated in the groove, moist air can enter the system at the leakage points.
Adsorbers of the VV-DV 1M and VV-DV 1L series are excluded

Saturated drying agent
When the desiccant is saturated, it can no longer absorb moisture. This allows moist air to enter the system.

Air 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.

Oil on the drying agent
If too many oil particles enter the adsorber, the oil particles close the pores of the desiccant and thus prevent adsorption.

Ambient temperature too high
If the ambient temperature exceeds 80°C, the binding forces in the desiccant decrease. This means that the incoming ambient air is only dried to a limited extent.

2. Positive or negative pressure builds up in the system
Air flow rate too high
Too high an air flow rate can cause over- or underpressure in the system.

Contaminated filter element
The filter unit can be clogged by dirt particles and can therefore build up pressure in the system.

Oil on the drying agent
If oil particles get into the adsorber, the spaces in the fill can be filled with oil and the fill will stick together. This can cause pressure to build up in the system.

3. Adsorber is damaged
Material resistance
When selecting the adsorber, the ambient and operating conditions should be considered. An aggressive environment or liquid in the container can damage the adsorber.

Temperature range
The ambient and operating temperatures should not exceed or fall below the specified range, otherwise the adsorber may be damaged.

Improper handling
Incorrect or improper handling can damage the adsorber. Please pay attention to the recommended installation.

Strong vibrations
Strong vibrations of the plant can damage the adsorber.

Pressure range of the system
The adsorber should not be exposed to over- or underpressure above 0.5 bar, otherwise the housing may be damaged.

Cleaning of the adsorber
For external cleaning of the adsorber, the use of a mild soap in combination with water is recommended. The use of brake cleaner will damage the adsorber and is no reason for complaint.

Thread of the adsorber and accessories is damaged

Thread of the adsorber and accessories is damaged
When mounting the adsorber on the system, the threads must be slightly moistened with oil. If the threads are not oiled, this can lead to the individual thread rubbing and is not a reason for complaint.

 

 


Maintenance plan

1. Check seals for wear

Check    The O-rings installed on the adsorber must be checked for perfect condition. For this purpose the seals on the valve part (3 in number) should be checked for brittleness.
If it is an adsorber of the VV-DV 1M, or VV-DV 1L series, only the O-ring at the connection needs to be examined.
Cycle    Half-yearly
Measures    In case of existing damage, new O-rings or a new adsorber should be used.

2. 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. If 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
Measures    If the silica gel is loaded or damaged by oil, a new cartridge or a new adsorber with fresh silica gel should be used.

3. Visual inspection of the adsorber

Check    The adsorber, including the connection, must be visually checked for damage. Damage can occur due to various environmental or operating conditions.
Cycle    Annually
Measures    If the adsorber is damaged, it must be completely replaced to ensure full functionality.

Order of spare parts

For a constant operational readiness of the adsorber and thus of the plant, make sure that a spare parts kit is always in stock.
The time until the complete colour change from colourless to brown and thus the service life of the adsorber depends on various factors:

  • Number and duration of flow and loading intervals.
  • Quantity of oil particles and mists emitted.

 

Storage of adsorbers

All articles filled with activated carbon are packed airtight. To avoid damage to the activated carbon, it must be stored in dark and dry rooms at -10°C to +30°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 and disposed of separately.
The loaded activated carbon must be disposed of according to the absorbed substance (e.g. hydraulic or gear oil).
Activated carbon and silica gel are not classified as hazardous substances under European Union legislation (Regulation EC No 1272/2008). It is not subject to mandatory labelling according to EC Directive (67/548/EEC or 1999/45/EC). Activated carbon and silica gel are not classified as substances hazardous to health or the environment.

 


Risk and hazard analysis

1. Oil flows out of the plant
Porous seals
Air containing oil can flow from the adsorber into the environment at the porous points. This means that no protection against oil mist in the air is possible.

Saturated activated carbon
When the activated carbon is saturated, it can no longer absorb oil. As a result, oil particles from the system are released into the air.

Air flow rate too high
If the air flow is too high, the contact time between oil particles and activated carbon is too short. This allows oil to flow out of the system.

2. Positive or negative pressure builds up in the system
Air flow rate too high
Too high an air flow rate can cause over- or underpressure in the system.

Contaminated filter element
The filter unit can be clogged by dirt particles and can therefore build up pressure in the system.

Activated carbon saturated
Once the activated carbon is completely saturated, oil can deposit and clog the adsorber.

3. Adsorber is damaged
Material resistance
When selecting the adsorber, the ambient and operating conditions should be considered. An aggressive environment or liquid in the container can damage the adsorber.

Temperature range
The ambient and operating temperatures should not exceed or fall below the specified range, otherwise the adsorber may be damaged.

Maintenance plan

1. Check seals for wear

Check    The O-rings installed in the adsorber and the flat gasket must be checked for perfect condition. For this purpose, the seals in the cover, on the filter and on the connection should be checked and examined for brittleness.
Cycle    Half-yearly
Measures    In case of existing damage, a new spare parts kit or a new adsorber should be used.

2. Visual inspection of the activated carbon

Check    The loading condition of the activated carbon must be determined by visual inspection of the adsorber. The colour white indicates that the activated carbon can still adsorb oil and that air is cleaned. If the activated carbon is completely saturated, the colour changes from white to brown.
Cycle    Half-yearly
Measures    If the activated carbon is loaded, a new spare parts kit or a new adsorber with fresh activated carbon should be used.

3. Check filter unit for impurities

Check    Remove the cover and remove the foam disk. Then empty the activated carbon. The filter unit can then be removed. This should be checked for impurities 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.

4. Visual inspection of the adsorber

Check    The adsorber, including the connection, must be visually checked for damage. Damage can occur due to various environmental or operating conditions.
Cycle    Annually
Measures    If the adsorber is damaged, it must be completely replaced to ensure full functionality.

5. Replacing the wearing parts

Check    The wearing parts, in particular the seals, the activated carbon and the filter element, must be checked with regard to their condition.
Cycle    Every two years
Measures    Regardless of the result of the test, it is recommended to replace the wearing parts by using a spare parts kit or a new adsorber to ensure smooth operation.
