Walk In Ovens and Truck In Ovens
What is the difference between a walk in and a truck in oven? One of the differences is size. Walk in ovens are usually smaller and require a smaller door. Truck in ovens may be larger in capacity and require a larger doors. Typically these ovens range from 170 to over 700 cubic feet in volume.

Walk in ovens often have racks on the side walls to accept shelving that can be manually placed. With truck in ovens, the material to be treated is placed on racks which are then brought into the oven by truck. Truck in ovens sometimes have doors on both ends allowing material to be moved on carts into the oven and after treatment out the other side while new material is moved into the oven
from the front.
Both ovens have a maximum operating temperature of 1200 F (650 C). They use either electric or gas to heat the oven.
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
