An improved paint bake oven (10) of a modular construction is disclosed as including a convection heating module (12), exhaust modules (64), and a radiant drying module (80). The heating module (12) includes outer and inner housings (14) and (16) as well as an upper central supply plenum (20) and a central upper return plenum (28) that cooperate to provide efficient gas flow to painted products being baked upon passage through the heating module. Each exhaust module (64) is connected to an associated heating module so as to receive and exhaust gas therefrom to the environment. The radiant drying module (80) is located upstream from the heating module (12) and includes an outer insulated housing (84), an inner housing (86) having side passages (92) located on opposite sides of a product passage of the drying module (80), and a heater (96) that supplied heated gas to the side passages (92) to provide radiant heating that initially dries the painted products.

A paint bake oven of a modular construction including a heating module comprising: an outer insulated housing; an inner housing received within the outer housing and defining a product passage through which products are passed; an upper central supply plenum located above the inner housing within the outer housing; said inner housing having perforated lateral side walls defining a bifurcated gas flow path from the supply plenum to the product passage; a central upper return plenum located above product passage and below the supply plenum; the inner housing having a perforated top wall through which gas flows from the product passage to the return plenum, and removable baffles that can be selectively attached to and removed from said perforated lateral side walls to cover and prevent flow through selected groups of said perforations for shutting off or controlling the amount of flow into said product passage from the space between said perforated side walls and said outer housing, and for directing and selectively concentrating the flow through selected portions of said perforated side walls into said product passage.
