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.
