Functionality

Removal of the substance from the container

Entry of moist

supply air into

the container!

Humidity

Absolute Humidity

Content of water vapor

Relative Humidity

Percentage to maximum

humidity

Content of water:

at 25°C and 90% rF → 20.7 g/m³

at 20°C and 80% rF → 13.8 g/m³

at 15°C and 60% rF → 7.7 g/m³

Temperature [°C]

T = 25°C Water 20.7g/m³

T = 20°C Water 13.8g/m³

T = 15°C Water 7.7g/m³

Operation Conditions

Environment with …

… high humidity > 70% rF

… high temperature > 25°C

Containers with …

… a hygroscopic substance

… a long storage time

Formation of Condensation 1

Ambient air enriched with

moisture

• Medium is removed from

the tank

• Level drops

• Pressure equalization by

incoming air

→ Inflowing air humidity

according to ambient air!

→ Moisture contaminates

substance

Damage as a result

• Crystallization and curing

• Clogging of pipes and

nozzles

• High maintenance costs

• Quality loss of the final

product

GIEBEL FilTec GmbH

Problem Solving Adsorber

Adsorption of water,

thereby lowering the

humidity and the dew

point.

→ Protection of the

substance contained!

Prevention of Condensation 1

Container WITH Adsorber

→ Use of an adsorber with

desiccant

Ambient air enriched with

moisture

→ No water in the

container!

→ No loss of quality of the

substance

Result

Humidity after Adsorber

average 10%rF

• Content of water: 1.7 g/m³

• Dew point: -12.5°C

GIEBEL FilTec GmbH

Adsorption

• Water molecules are bound in the pores

• Adsorption based on attractions (Van der Waals forces)

• Van der Waals forces are again soluble → Desorption

• Maximum load, until equilibrium!

Air Drying

Substance is removed:

Air is sucked in and flows through adsorber

→ absolutely dry air
