GIEBEL Adsorber^®

Barrels & IBC

BARRELS & IBC

Fässer & IBC

In the storage and processing of substances in barrels and IBC containers moist air is attracted from the environment. This humidity contaminate the stored media. For example, it comes with isocyanate to crystallize, oils are saturated with water and biological fuels forming bacteria and mud. For the protection of hygroscopic substances in drums and IBC's various respiratory dryers GIEBEL can be used.

Whether vertical or horizontal drums, whether plastic or stainless steel IBCs, whether container breathing or active substance removal, a rectly set Drum aeration filter ensures clean and dry air supply.

FORMATION OF WATER IN THE TANK

IBC WITHOUT Adsorber
-> Use of a ventilation filter without desiccant
Ambient air enriched with moisture
Removal of the substance from the container
Level drops
Pressure compensation by incoming air
-> Incoming air humidity corresponding to ambient air
Moisture contaminates substance

FUNCTIONAL BARRELS & IBC - HUMIDITY AND DEW POINT

Removal of the substance from the container

Entry of moist supply air into the container!
Absolute Humidity
Content of water vapor
Relative Humidity
Percentage to maximum humidity

Example
Temperature = 20°C
Air humidity = 80% rF

-> Water 13.8g/m³
-> Dew point 16,4°C

-> Permissible temperature range = 3,6°C

DAMAGE CAUSED BY WATER

SCHÄDEN DURCH WASSER

Crystallization and curing
Clogging of pipes and nozzles
High maintenance costs
High maintenance costs

AVOIDANCE OF WATER IN THE TANK

IBC WITH adsorber
-> Desiccant in use
Ambient air enriched with moisture
Inflowing air with humidity from the environment flows through the adsorber
-> Moisture remains in the desiccant
-> No water in the container
-> No loss of substance quality

Adsorber lowers the air humidity to below 2%RH
and the dew point to below -40°C
Humidity after Adsorber
average 10% rH
Content of water: 1,7 g/m³
Dew point: -12,5°C
