Lab/bench ovens are typically used in the industrial setting when small batches of product are needed or the size of the workspace is limited.  These ovens are often positioned on a table or bench, but can also be floor mounted depending on the setting.  They often use trays to bring the part being processed into the oven.

Cabinet ovens, also referred to as reach-in ovens, are recommended for use in an industrial setting when the product you are working with can be easily inserted into the oven by hand.
