Electric Medium-Wave IR Web Drying Oven – dries ink on a paper web that runs 1,450 FPM!!

Wisconsin Oven manufactures web ovens and strip cure ovens, where steel, aluminum, plastic, or paper is processed as a continuous web onto which a pretreatment, coating, or paint is applied. An oven, also known as a dryer, is used to cure the coating on the web using convection technology, where heat energy is transferred to the product through forced air. Infrared (IR) can also be a solution for some applications. Pressurized duct plenums are typically located above and below the web to direct heated air onto the web through regularly spaced louvers. Since the web hangs at a catenary as it travels through the oven, the ducts are designed to follow the shape of the catenary to optimize heat transfer. The ducts can also be vertically adjustable to allow final adjustments and fine tuning during commissioning of the equipment at final job site.

Wisconsin Oven web dryers utilize multiple zones of control, for both the recirculation and heat, for accurate temperature control under changing conditions. Each zone can be operated at different temperatures to provide optimum cure and maximize line speed. Each zone typically includes its own separate exhaust port, to insure complete dilution of all solvents and fumes that are released during the heating process.


A good example are these four (4) catenary-style web/strip cure ovens which are stacked vertically. There are a total of eleven (11) zones of control, and each heat zone includes a separate solvent monitor. The oven is over 24'0” high x 90' long and has a maximum operating temperature rating of 600°F. There are 120 access doors along the sidewall for ease of installation and maintenance. This strip cure oven is rated for a maximum rating of 12,400,000 total BTUH. The ductwork is arranged to provide airflow onto the web from both above and below. The supply ducts are contoured to follow the strip catenary and have removable access sheets for cleanout. This web oven was installed and commissioned by Wisconsin Oven Corporation.

The strip cure oven ductwork (as shown to the right) directs heated air onto a web of steel or aluminum traveling at 400 FPM. Air impinges from both the top
and bottom. The ductwork follows the catenary of the web and is vertically adjustable.

Since web processing typically involves material traveling at speeds of 400 FPM or more, there can be a high volume of solvents released, and the exhaust from the oven may need to be processed through a fume incinerator (thermal oxidizer) to eliminate the VOC’s. Solvent monitors (LEL detectors) are often used to reduce the risk of fire due to a solvent overload condition. Continuously monitoring the solvent level will provide a more fuel efficient operation, as the exhaust rate can be reduced without compromising safety.

Our strip curing equipment is completely factory assembled and tested. We can supply solvent detection, controls, fume incinerators, as well as a wide range of other optional items. We also can work closely with material handling suppliers of your choice for ease of installation.
