Walk In Oven

Compare WALK IN OVENS and TRUCK IN OVENS. A walk in oven is a large batch oven. The difference between the walk in ovens and the truck in ovens requires trucks to load the material while the walk in oven has shelves in place. These ovens range in size from 100 cubic feet (2800 liters) to over 700 cubic feet (20,000 liters). Walk in ovens and truck in ovens are used for aging, curing, heat shrinking, annealing, powder coating, and other thermal batch processes.

Walk in ovens and truck in ovens have a maximum operating temperature of 1200 F (650 C). They use either electric or gas to heat the oven. The temperature controls for walk in and truck in ovens come with set-point control as standard with digital and programmable controls are available as an option.

Typically, walk in ovens and truck in ovens have a pair of side swinging doors, although some ovens only have a single door. Some ovens, especially the truck in ovens, will have two sets of doors, one at either end of the oven. This arrangement allows a truck to be removed from the oven while another truck is being loaded into the oven at the same time. Shelves, mounting or hanging racks are available on most walk in ovens and flat bed and shelf trucks for truck in ovens. The interior of walk in and truck in ovens is either aluminized steel or stainless steel.

Walk in ovens and truck in ovens have either a natural convection or a forced air convection airflow. Either airflow can be horizontal or vertical. Natural convection, also known as gravity convection, uses an opening to allow the air to escape and set up an airflow. Forced air convection uses fans to create the airflow. Forced air convection can also be compound horizontal. The compound horizontal airflow has fans on both sides of the oven pushing the air toward each other causing an upward airflow in the center of the oven.
