Item No.:

PS220-R68 Double Unit

Principle

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 Middleby ovens are designed to cook a multitude of products, including pizza, seafood, bagels, Mexican, etc.

Double Models Direct Gas Fired

Conveyor Oven

General Information

PS220 conveyor ovens feature a 40.5" cooking chamber, and a patented “Jet Sweep” convection process that delivers constant heat to the chamber. All ovens feature microprocessor controlled bake time/conveyor speed. Six adjustable jet fingers and front-loading window are standard. Ovens have stainless steel front, sides and top. All ovens include extra fan belt, installation kit, restraining cable, and 4' AGA flex hose. Heating is controlled in 8" adjustable zones. Top and bottom are independently adjustable. The conveyor drive is reversible. Conveyor belt provides automatic delivery when product is finished. Front loading window with cool handle design allows product with different bake times to be cooked consistently regardless of loading.

Special Features

PS220 Units are stackable two high, with tandem options available. Split belt option and left hand controls are also available upon request.

Conserves Energy

Middleby ovens provide very efficient heat transfer to product. Energy is conserved as air is recycled from heater to product, with minimum flue or vent loss.
