DTI-1118 Inert Atmosphere Batch Oven
CUSTOMER DIRECTIVE
Our customer wanted to create an indexing single part flow inert atmosphere production furnace system to match, and seamlessly integrate into, the customer’s entire existing manufacturing process at a production rate of 45 seconds part to part. The customer’s then existing process included inefficient batch furnace staging of parts at this point in the process.
DESCRIPTION
The DTI-1118 inert atmosphere batch oven is used in the manufacturing of membranes that are used in blood purification processes.The oven can accommodate up to four (4) rolls of membrane in the oven per batch. A series of dampers allows the nitrogen atmosphere to circulate throughout the oven chamber, through the center of the membrane roll, or both. The purge cycle is automatic, and nitrogen is supplied to the chamber until the oxygen level has reached less than 1%.Once the oxygen level is below 1% the heat cycle begins.
The PLC control system allows the oven to accommodate multiple heating profiles for different products. The oven can run both non-nitrogen profiles and nitrogen atmosphere profiles.
