Wisconsin Oven is pleased to announce the shipment of one
(1) Electrically Heated Standard Draw Batch Oven (SDB Series) to a United States Military Base. This industrial oven will be used for heat treating various aerospace components.
This equipment is engineered to meet the critical safety requirements of the customer and stringent demands of aerospace heat treating. It has combination-style airflow (delivering both horizontal and vertical upward flow) to ensure optimal heating rates and consistent temperature distribution across the product. Uniformity has been verified through a Class 1 Temperature Uniformity Survey (TUS) conducted at Wisconsin Oven’s facility in accordance with pyrometry specification AMS 2750H. The system achieved temperature uniformity of ±5° F at 200° F, 700° F, and 1,200° F.
This SDB series oven is built with “CAN” style construction that includes a heavy plate exterior and 6” of high-temperature industrial insulation. This construction maximizes durability and thermal efficiency. A custom designed portable load/unload cart allows operators to precisely stage the load in front of the oven before heating and remove it post-cycle for cooling.
The oven’s control panel is UL508A certified and equipped with a Eurotherm 3504 programmable temperature controller with fast acting advanced auto-tune and ethernet communication capabilities. A high-limit instrument is also included to prevent over-temperature conditions during operation. Low voltage calibration TC Jack plugs, and a variable frequency drive (VFD) for the recirculation blower were additional features included.
“This draw batch oven was designed with additional safety features for operators, tight uniformity, and compliance standards required by the US Military. The temperature uniformity survey was performed prior to shipment to verify compliance with AMS 2750H Class 1 requirements.”
– Doug Christiansen, Senior Application Engineer
Unique features of this heat treat oven include:
- Temperature Uniformity of ±5°F at 200°F, 700°F, and 1,200°F (AMS 2750H Class 1 verified)
- Vertical lift pneumatically operated door with manual and automatically actuating door safety latches (to provide redundant vertical lift door safety features for personnel)
- Portable load/unload cart which is interlocked with the oven door to disable door actuation when the cart is being loaded or unloaded in front of the oven
- Eurotherm 3504 programmable temperature controller with Ethernet communication
- Motorized dampers on fresh air inlet and exhaust outlet to allow low temperature operation and faster cooling
- 15,000 CFM @ 10 HP recirculation system utilizing combination airflow and a VFD (for lowered noise level, and improved heat loss while the oven door is open)
- Low voltage calibration TC Jack plugs connected to all thermocouple inputs to allow personnel to calibrate the analog thermocouple inputs to alleviate the need for personnel to enter the high voltage main control panel where arc flash PPE would be required
This draw batch oven was fully factory tested and adjusted prior to shipment from the Wisconsin Oven 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 Exclusive and Unprecedented 3-Year WOW™ warranty.
