Middleby Marshall Oven PS528E User Manual

PS528E

Electric 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.

General Information

The PS528 conveyor oven is ideally suited for Kiosk and
express-style locations where smaller ovens are required.
