THE IMPORTANCE OF HUMIDITY CONTROL
The lack of humidity control affects:
• Comfort: Environmental Wellness
• Health: Respiratory diseases, viruses, bacteria, allergies, etc.
• Materials: Hygroscopic and corrosion.
• Static Electricity: Risk for materials and people. Discomfort.

• To reach dew points <10ºC
• To reach Absolute humidity points < 8,5 g/kg
• Desiccant dehumidification is more efficient at low relative humidity and temperature , and it’s cheaper than mechanical dehumidification a DBT<20ºC
• The best option and when both systems works better is by combining the mechanical (first step) and desiccant (second step)
• Most cases, the choice is not an easy decission. Energy cost will be the key factor

REQUIRED CONDITIONS: 22ºC, 30%HR, 4,9 g/kg
Why do we need DRY AIR?
• To avoid the product absorves humidity
• To avoid condensation and microbiological problems in the storage
• To Increase blistering speed (more production)
• To decrease the number of maintenance interruptions
• Direct dry air inside the blistering cabinet (smaller size of the dehumidifier)
Application: BLISTERING

Application: STERILE AREA
REQUIRED CONDITIONS: 22ºC, from 10% to 30%HR (1,6 - 4,9 g/kg)
Why do we need DRY AIR?
• To avoid the product absorves humidity
• To avoid microbiological growth when low humidity
• Dry air mixed before the AHU

Application: GELATINE CAPSULES
REQUIRED CONDITIONS: 22ºC, from 4% to 10%HR (0,6 - 1,6 g/kg)
Why do we need DRY AIR?
• To dry the gelatine capsules
• To decrease non-quality products
• Direct dry air inside the cabinet
• To Increase drying process,more production

Application: ACCELA COTA MACHINE
REQUIRED CONDITIONS: 22ºC, 4%HR (0,6 g/kg)
Why do we need DRY AIR?
• To help coating the product
• To increase speed of production
