Humidity Control System

The purpose of the Humidity Control System (HCS) is to regulate the amount of water vapor within a controlled environment while in microgravity. The unique water collection system prevents air entry and allows the liquid water to be recycled for use elsewhere within the system. The system shown above was used to maintain humidity control within the BPS plant chambers. 
 

Size ..................................................................................................................................................................... 5.5" x 2.5" x 1.8"

Weight ................................................................................................................................................................................ 11 oz

Typical power .................................................................................................................................... 20 W (high humidity generation)

Typical control range ................................................................................................................................................. 60% - 95% RH

Actual power and control range are dependent on application, air flow rate, and humidity generation rate. 
 

• The HCS can be directly inserted into a variety of applications or customized to meet specific requirements and control ranges. Typical applications may include controlled environments for plants, animals, insects, small habitable volumes, and work stations.
