Microwave technology can be advantageous for industrial scale heating, provided the application benefits from the unique aspects of microwave heating outweigh those of conventional heating. However, setting up an efficient, cost-effective industrial-scale microwave heating system requires understanding application-specific processes and design constraints.

In this application note, we describe a set of relatively simple considerations that aid the non-specialists in assessing whether microwave technology may be advantageously employed in a particular heating application. We also review some of the primary factors that should be taken into consideration when designing an industrial scale microwave heating system.
