Industrial Microwave Heating
Thermal processing
Thermal processing is widely used across industries but remains highly energy-intensive, especially with conventional furnace-based methods. As decarbonization becomes a strategic priority, manufacturers are shifting toward fully electric heating technologies — able to run on renewable energy and significantly reduce the carbon footprint of their thermal processes.
Thermal processing with microwave technology
Thermal processing with microwave technology delivers faster, more uniform heating, directly within the material. This technology improves superior process efficiency and reduces cycle times.
Key advantages of microwave heating
Decarbonized solution
Microwaves are fully electric and can use green electricity
Energy efficiency
Microwave heating reaches up to 80% energy efficiency — far above conventional thermal methods
Fast process
Energy penetrates directly into the product — power is absorbed by the material itself, ensuring fast process
Instant start
No warm-up needed. Flexible production with instant start capability
Selective heating
Microwaves allow the heating of the chosen material, depending on the dielectric properties of the product
Controlled heating
No risk of overheating, ensuring homogeneous and consistent heating throughout the material
Reliability
Consistent and repeatable results, every time
Pre-heating & heating
Use microwave as a boost stage — before or after conventional heating — to significantly reduce processing time
Products that can be processed
Microwave technology can heat any high-value product — provided its dielectric properties allow it. SAIREM supports you in implementing a tailored microwave solution, offering tests and simulations alongside our equipment to validate the relevance of microwave technology in your industrial process.
Material heating
Heating materials volumetrically, ensuring uniform temperature distribution while reducing processing time and minimizing thermal stress
Everything You Need to Know: How Microwave Can Be Used in an Industrial Thermal Process.
Yes. An industrial microwave system can be used as a standalone process or as a final heating step, seamlessly integrating into existing lines to reduce overall processing time and energy consumption.
Thanks to volumetric heating, energy is absorbed directly by the product — ensuring homogeneous heating without surface overheating.
