Wisconsin Oven has shipped one inert atmosphere batch oven with an atmosphere-to-water cooling system to a defense industry manufacturer. The oven will be used for processing stainless steel parts in a reduced oxygen environment to prevent scaling.
The maximum temperature rating of this oven is 1,250°F and it has the capacity to heat and cool approximately 6,000 pounds of steel per load in an inert atmosphere. The temperature is controlled by a Watlow F4T digital recorder/controller with Ethernet communication capabilities. Guaranteed temperature uniformity of +/- 10°F at 1,000°F and 1,200°F was verified with a nine-point profile test.
The batch oven is designed to use a nitrogen atmosphere system to reduce surface oxidation of the parts. The system includes a flow meter calibrated for nitrogen and controlled via a closed loop to maintain the reduced oxygen level. Oxygen and humidity sensors provide real-time monitoring, and a modulating valve is used for variable purge control.
The oven features a “CAN”-style construction with a heavy plate exterior, a total of 6 inches of insulation, and an 18 gauge 304 stainless steel interior. To maximize throughput and productivity, the oven is designed with a pneumatically operated vertical lift door and powered load/unload table capable of handling up to 6,000 pounds, along with a water cooling system to reduce the cooling time, to allow for faster production cycles.
“This inert atmosphere oven includes several state-of-the-art features that increase production throughput and provide reduced surface oxidation,” said Mike Grande, VP of sales. “These include water cooling to reduce the cooling time at the end of the cycle, closed-loop nitrogen control to prevent nitrogen overconsumption, oxygen and humidity sensors to provide real time data, and an industrial IoT system to connect the unit to the Wisconsin Oven aftermarket team for remote data monitoring and tech support.”
Unique features of this inert atmosphere batch oven include:
- Temperature uniformity of ±10°F at setpoints of 1,000°F and 1,200°F.
- Nitrogen atmosphere system.
- Water cooling system.
- Pneumatically operated vertical lift door.
- Powdered load/unload table.
- Data-Sense® IOT equipped for monitoring and real-time data.
- Supervised installation with start-up and training.
This atmosphere batch oven was fully factory tested and adjusted prior to shipment from our facility. All safety interlocks were checked for proper operation and the equipment was operated at the normal and maximum operating temperatures. An extensive quality assurance check list was completed to ensure the equipment met all Wisconsin Oven quality standards. This equipment is backed by Wisconsin Oven’s 3-Year WOW™ warranty (parts only).
