Web Dryers & Strip Cure Ovens

Product details

Wisconsin Oven manufactures industrial web dryers and strip cure ovens for processing steel, aluminum, plastic, or paper as a continuous web after a pretreatment, coating, or paint is applied. An industrial 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 high velocity forced air. Pressurized duct plenums are typically located above and below the web to direct heated air onto the web through regularly spaced louvers. If the material hangs at a catenary as it travels through the dryer, the ducts are designed to follow 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 the 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 dilution of all solvents and fumes released during the heating process.

Since web processing often 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, by minimizing the exhaust rate without compromising safety.

NOTE: Wisconsin Oven does not manufacture flotation ovens.
