The Middleby Series PS200-R68 Oven is a conveyorized
hot air oven employing vertical air streams (Figure1-3) to
give uniform and intensive heating. The columnated
vertical streams of hot air provide an exceptional heat
transfer rate and generally bake faster and at lower
temperatures than convection hot air or infrared heating
ovens.
