Direct Gas Fired Conveyor Oven
PS224 Single Unit
PS224-D 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 that tend to insulate the product. This
process allows rapid baking without burning. All
Middleby ovens are designed to cook a multitude of
products, including pizza, seafood, bagels, ethnic
foods and more.
General Information
PS224 conveyor ovens feature a 40.5" cooking
chamber, a 24" wide conveyor belt and the patented
“Jet Sweep” impingement 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 installation kit, restraining cable,
4' AGA flex hose and brushed steel legs. Heating is
controlled in 8" adjustable zones. Top and bottom
heating is independently adjustable. The conveyor
drive is reversible and provides automatic delivery
when product is finished. Front loading window with
cool handle design allows products with different bake
times to be cooked consistently regardless of loading.
Special Features
PS224 units are stackable two high, and split belt
option is available upon request.
Conserves Energy
Middleby ovens provide efficient heat transfer to
product. Energy is conserved as air is recycled from
heater to product with minimum flue or vent loss.
Cleanability
PS224 ovens are designed for easy cleaning.
Removable parts include crumb pans, end panels, air
fingers and a folding conveyor belt assembly for easy
removal.
Easily Serviced
Control compartment is designed for quick and easy
access. All electrical controls are door-mounted.
Warranty
All PS224 models have a one year parts and labor
warranty. Oven start-up and demonstration are
included at no additional charge (USA only).
Ventilation
For installation under a ventilation hood only.
