PS528G
Direct Gas Fired Countertop Conveyor Oven
Principle
Middleby Marshall PS Series conveyor ovens bake both faster and at a lower temperature
than other ovens. Vertical columns of hot air move heat aerodynamically instead of using high
temperatures. The streams of hot air remove the boundary layers of cool heavy air which tend to
insulate the product. All Middleby ovens are designed to cook a multitude of products including
pizza, seafood, sandwiches, bagels, ethnic foods and more.
