3. Brief History
Cargocaire (CEC) was founded in 1939 by Commander Colvin to protect cargo aboard merchant and naval vessels.
Munters Corporation was founded by Carl Munters in The two companies merged to create Munters Cargocaire.
Nick Des Champs develops air-to-air counter flow heat exchanger in 1973 for cooling jet fighter cockpits. Des Champs Laboratories incorporated in 1974.
Munters acquires Des Champs Technologies in 2007.

14. Humidity and Dew Point Control
Spray Drying
No clogs in product collectors (increases throughput)
Allows smaller spray towers, fluid beds and heaters
Improves product quality

15. Spray Drying Process

16. Spray Tower Problems Production rate varies by season
Drying time too long
Inconsistent quality of the powder
Production stops
Product scrap
Lack of flexibility

17. Typical Production Losses Related to Moisture in the Air

18. Munters Approach
Using desiccant technology to dry the outside air required for the process (GTR).
Provide a consistent low dew point (winter time conditions year round).
Desiccant wheel removes moisture while also heating the process air (energy savings).

20. Cooling-Based Dehumidification
Air is circulated across a cold coil and cooled to saturation
Further cooling condenses moisture from the air stream
Dewpoint reduction is limited by minimum practical coil temperatures
Air is delivered at saturated conditions

33. Summary If the customer currently has no humidity control:
Desiccant Dehumidification will supply winter time humidity conditions year round.
If the customer already uses cooling for humidity control
Desiccant Dehumidification will provide better humidity control for less energy.
If the customer already uses a competitors desiccant system:
Munters GTR wheel will provide better performance for less energy
