Abstract
An oven having one or more independently adjusted radiant heaters that can be dynamically adjusted before and during a curing or heating process to account for the shape and size of an object being cured or heated, further comprising a means for dynamically controlling the level of heat output from the radiant heaters. The oven preferably has radiant heaters positioned on opposing sides of the object and one or more back panels positioned behind the radiant heaters to absorb any radiant heat that misses the object. The oven of the present invention also has a turbulent fan and a means for deflecting the air flow of the convection heat throughout the internal oven chamber and toward the object. In addition, the oven has an exhaust fan that can discharge the exhaust either outside of the oven or redirect the exhaust back into the oven chamber to raise the ambient temperature, depending on the application for which the oven is being used. A computer system uses one or more object sensors and ambient sensors to control the radiant heaters (both position and level of heat output), the turbulent fan, the exhaust fan, and water flow to the object sensor. The oven of the present invention …
