Wisconsin Oven Corp. (East Troy, Wis.) has 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°F (80°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 that maximizes heating rates and temperature uniformity of the product. Per the manufacturer’s request, the ovens required a temperature uniformity of ±2°C, and they actually achieved ±1°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. In this case, we guaranteed a very tight temperature uniformity to help create consistent end results,” says Mike Grande, senior application engineer.

Unique features of this batch oven include:

  • Temperature uniformity of ±1°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” to provide clear width of 79” with the doors opening at 90°
  • An additional pushbutton station at the front of the oven for operator convenience
  • Increased heaters from 8kW to 12kW
