DTI-1239 Inert Atmosphere Batch Oven
Description
The DTI-1239 inert batch oven is used to dry aluminum parts. The oven is a top load type oven and parts are placed in a basket for drying. The oven door is pneumatically actuated and opens and closes automatically.
The sequence of operation for the oven is as follows:
- The hinged door opens
- An automated transfer system places the basket of parts in the drying chamber
- The hinged door closes
- The high-flow nitrogen system purges the oven chamber based on a predetermined time.
- Once the chamber is purged to the correct atmosphere the nitrogen system changes to constant low-flow and maintains the chamber atmosphere for the duration of the drying cycle.
- The chamber is then heated to 150⁰F and the timed drying cycle will be completed.
- Upon completion of the drying cycle the heat is turned off and a cooling cycle begins. The nitrogen flow can be changed to high-flow during cooling to decrease the cooling cycle.
- Upon completion of the cooling cycle the nitrogen flow is stopped and the chamber is purged to remove the nitrogen.
- The door opens and the basket of parts is removed by the automated transfer system.
- The process is then repeated.
