Ideal for simultaneously preparing multiple products, the Middleby Marshall PS638G-2 WOW! conveyor oven is designed with two separate baking chambers, each with a bake time range of 1 to 12 minutes. Each chamber’s temperature can be set as high as 600 degrees Fahrenheit, which users can adjust using electronic controls. To streamline cleaning in busy kitchens, this unit is equipped with a removable crumb pan.

To ensure corrosion resistance and strength, the top, sides, front, and interior of the Middleby Marshall PS638G-2 conveyor oven are constructed of stainless steel. For safe operation in fast-paced environments, the exterior remains comfortably cool to the touch when in use. Enabling users to wheel it between locations for service or cleaning, it comes with casters.
