DTI-1123 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-1123 custom inert batch oven is used in the plastics industry for annealing product. Approximately 2,000 pounds of product (plastic rods) are loaded into the inert atmosphere oven via a custom product cart. The purge cycle is automatic, and nitrogen is supplied to the chamber on high flow until the oxygen analyzer reaches 5%. the nitrogen is then provided on low flow until the oxygen analyzer reaches 2% allowing the heating cycle to begin.
The oven ramps to 375°F in (4) hours. The product then soaks at 475°F to 500°F for (8) hours. At the completion of the heating cycle, the product is cooled down to approximately 150°F. Cooling is provided by a cooling jacket that utilizes ambient fresh air.
