Middleby Marshall PS Series Conveyor ovens bake both
faster and at a lower temperature than other ovens. Patented 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. This gives very rapid baking
without burning. All PS670WOW ovens are designed to
cook pizza 30% faster than other conveyor ovens.
Cleanability
PS670 ovens are designed for easy cleaning. Removable
parts include: crumb pans, end panels, air fingers, and a
folding conveyor belt assembly.
Easily Serviced
Control compartment is designed for quick and easy access. All electrical controls are door-mounted.
Warranty
All PS670 models have a one year parts and labor warranty. Oven start-up and demonstration are included at
no additional charge (USA only).
