The desired outcome is for the combination of pretreatment, application, and cure to produce a coating with specific physical and chemical properties. Understanding the operation of a convection oven requires the examination of the systems at work within the unit. There are five major components in an oven: the shell, the heater, the supply system, the circulation system and the exhaust system.

Each of these has an essential function, is comprised of several interlocking parts, and is subject to problems from bad adjustment and misapplication. When they work together properly, they produce the process necessary for the successful cure of a coating.

The oven tunnel is self-supporting construction. The insulation panels are manufactured as sheet metal cassettes with tongue and grove joints. The panel frames consist of sheet metal plates with slots arranged in opposite, in order to prevent heat losses by leaks. The panels are fitted together by means of tongue and grove joints with a sealing groove, no clamping devices or screws are required.

Solvent or humidified air is exhausted by exhaust fans.

Air ducts are designed as to match the requirements of the shape and type of the parts.
