A heavy-duty walk-in oven passed the temperature uniformity requirements to meet BAC 5621 Class 1 Furnaces and Instrumentation Type D specifications. Wisconsin Oven Corp. shipped the curing oven to a composite manufacturer.

Epcon Industrial Systems was selected to build an industrial oven with two combustion chambers located on top and three guillotine doors. The large unit, which will cure airplane parts, was funded by the United States government with a comprehensive site factory acceptance test (FAT) and on-site commissioning. 

In an interview with Editor Linda Becker, Wisconsin Oven’s Mike Grande shares further insights about ovens for curing composite materials.

Emerging developments in modern technologies — space exploration, high efficiency vehicles, aircraft manufacturing and wind power — are driving the demand for stronger and lighter materials. Composite materials are one of the best candidates to meet these “light weighting” needs.

Suitable for curing coatings, No. 865 has a 30" x 18' x 15" work zone and 90 KW (30 KW per zone) installed in Incoloy-sheathed tubular heating elements. 

An electrically heated walk-in oven will be used for composite curing small parts. It has the capability to heat 16,000 lb of a composite material from 70 to 350°F (21 to 177°C) within six to seven hours. The unit was shipped to a company in the technology industry.

When it comes to heating and drying needs on construction sites, a fuel-efficient system can significantly affect operating costs. The major types of heating systems are direct-fired open flame, indirect air and circulating water (hydronic). Hydronic heaters offer good fuel efficiency and do so while minimizing fire risk.

Infrared heaters are used to transfer heat through a process or to a product via radiation.

A major U.S. manufacturer of electronic components placed an order worth over $3 million with Despatch for inert atmosphere ovens. The PND oven is currently used by the manufacturer for critical thermal processing needed to cure electronic components.

Whenever infrared is used to heat, predry, dry or cure continuously traveling web material — or a continuous stream of flat materials supported on a conveyor — there is a risk of a natural phenomenon referred to as the edge-cooling effect. If the material exceeds 24” in the cross-machine direction (CMD) dimension, edge cooling will occur.
