The standard features of this product include a removable 6-1/2" long extended load/unload area, analog controls for conveyor belt speed and top and bottom heat, and a removable countertop oven crumb tray for easy clean-up. The compact design allows for stacking two (2) high with the 210HX and 214HX models, or three (3) high with the 314HX model using the optional stacking kit. The product entry and exit openings are adjustable from 1-1/2" to 3" for the 210HX and 214HX models, and from 1-1/2" to 4" for the 314HX model. The high-power quartz infrared elements are located above and below the conveyor belt, ensuring precise and even heating of products. The convection system keeps the conveyor oven cool-to-the-touch and extends the life of critical components, while also increasing productivity by circulating preheated air into the toasting chamber. Please note that there are more restaurant equipment, cooking equipment, and commercial ovens available. Additionally, a stacking kit is available as an option and accessory.
