Frequently asked questions about industrial microwave heating and our industrial ovens
Conventional heating relies on heat transfer from the surface to the core of the material, which can create temperature gradients and longer processing times.
Microwave heating is volumetric: energy is transferred directly into the product according to its dielectric properties. This enables faster heating, improved temperature uniformity and better control of thermal profiles.
Unlike conventional heating methods, microwave technology heats the material from within rather than relying only on external heat transfer.
This direct energy transfer reduces processing time, limits overheating risks and enables more precise control of heating conditions. The result is improved process efficiency, product quality and repeatability.
Microwave heating can achieve significantly higher energy efficiency than conventional thermal processes because energy is transferred directly into the product, reducing heat losses to the surrounding environment.
By optimizing microwave power delivery and applicator design, Sairem systems maximize energy absorption and reduce overall operating costs.
The InnoThermo ensures consistent and homogeneous heating through volumetric microwave heating: microwave energy penetrates directly into the product, reducing hot spots and thermal gradients.
Combined with Sairem expertise in applicator design, frequency selection and microwave energy control, each system is engineered to match the dielectric properties of the product, ensuring reliable and repeatable results.
Engineered to maximize energy absorption directly by the product, the InnoThermo benefits from Sairem’s more than 45 years of expertise in microwave and radio frequency technologies.
This experience is reflected in every system design, ensuring optimized energy efficiency, reduced operating costs, precise heating control and superior process performance.
Yes. The InnoThermo can be used as a standalone heating solution or integrated as a pre-heating or final heating stage within an existing industrial process.
Sairem designs customized solutions adapted to product properties, production requirements and process objectives.
Industrial microwave heating can be adapted to a wide range of high-value products and materials.
The InnoThermo is customized according to product composition, dielectric properties, moisture content and required temperature profile to achieve optimal heating performance.
Volumetric heating: fast and uniform energy transfer
Volumetric heating uses microwave energy to generate heat directly inside the product, enabling faster, more uniform and energy-efficient industrial processing.
