Wisconsin Oven Corporation shipped 10 electrically heated enhanced duty walk-in series ovens, each a Model EWN. The ovens will be used for curing wind-turbine components.
The maximum temperature rating for all the ovens is 176 degrees F (80 degrees C). The chamber dimensions are 6’6” W x 4’0” L x 6’0” H.
The ovens have combination airflow which provides both horizontal and vertical upward airflow which maximizes heating rates and temperature uniformity of the product. Per the manufacturers request, the ovens required a temperature uniformity of ±2 degrees C, and they actually achieved ±1 degrees C in practice.
The ovens also include a Eurotherm Nanodac paperless digital recorder with 50 MB of flash memory. This feature allows the manufacturer to store three months of data at a time.
“We strive to design our equipment to provide the best quality part results for our customers,” said Mike Grande, senior application engineer. “In this case, we guaranteed a very tight temperature uniformity to help create consistent end results.”
Unique features of this batch oven include:
- Temperature uniformity of ±1 degrees C.
- Digital Eurotherm 3504 programmable temperature controller.
- Increased recirculation fan CFM and HP to achieve the guaranteed temperature uniformity.
- Additional thermocouple probes inside the ovens.
- Increased heating chamber width by 6 inches to provide clear width of 79 inches with the doors opening at 90 degrees.
- An additional pushbutton station at the front of the oven for operator convenience.
- Increased heaters from 8 kW to 12 kW.
The walk-in ovens were fully factory tested and adjusted prior to shipment from Wisconsin Oven’s 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. The industrial conveyor oven is backed by Wisconsin Oven’s 5-year warranty. This warranty covers all materials for all components (less wear items).
