Walk-In Kit Ovens

7 Standard Sizes - Gas-Fired Heat

The KWN is a cost-effective alternative to our standard SWN walk-in batch oven line. It is designed and manufactured to be shipped as a kit, where the customer assembles the oven body and installs the main components at the final job site, which reduces the initial investment. The control panel and gas train, as well as the doors, are factory assembled prior to shipment. Each KWN batch oven features top-down air flow, with supply ducts located along each side of the chamber for air distribution along the entire length of the chamber.
