2.  Project Background  PDS Summary  Internal Search  External Search  Design Evaluation  Current Progress

3.  Objective: Produce a retrofit-able sealant oven capable of controlling humidity and temperature that allows for more efficient flow control  Current Methods: Large size - inefficient flow control Anchored to floor - Costly to move

4.  Performance RH 50 ± 5% @130 ± 5 o F Un-plumbed  Ergonomics < 35 lb supply

5.  Atomizing water Advantages ○ Inexpensive ○ Suitable for lower temperature and lower humidity Disadvantages ○ Droplet/moisture formation ○ Temperature change

6.  Steam injection Advantages ○ Higher RH (100%) ○ Dry process ○ No temperature change Disadvantages ○ Delay initial steam supply ○ More complex design ○ Expensive (steam generator)

7.  Boeing’s traditional humidity controlled oven Steam injection ○ Humidity control ○ Over sized-poor flow control ○ Plumbed system

8.  Green roof simulator Measures effective R value for green roofs Simulates environmental conditions Utilizes steam injection / RH controls
