Émetteurs infrarouges RadiantLine™ – Chauffage radiant industriel

Q: How do you choose between short and medium waves?

The key difference is penetration. Short waves heat surface and core simultaneously : ideal for liquid paint, thick or translucent materials, and densities above 100 kW/m².Medium waves heat the surface homogeneously : powder coating, textiles, composites, paint on glass. When the choice is not obvious, we test your material in our laboratory. 80 years of activity, thousands of tests: we have very probably already encountered your case.

Q: Are your emitters available in custom dimensions?

The RadiantLine™ range is available in several standard formats, combinable and adaptable to fit your installation constraints. For specific needs outside the catalogue, our design office analyses every request. Contact us with your dimensional and power constraints.

Q: Can I combine different technologies on the same line?

Yes. We combine short and medium waves, electric and gas, on the same line when the process demands it. We also intervene for retrofit on existing hot-air lines by adding an infrared oven — often at the start of the line — which enables the entire installation to gain in productivity and performance while reducing overall footprint.

Q: How do you validate the right emitter before integrating it in series?

We have a testing laboratory where we test your real materials before any commitment. Equipment rental is also available for testing under industrial conditions.

Q: What is the service life of a Sopara emitter under continuous industrial conditions?

Our ribbon MIR emitters are designed for 5 to 10 years of continuous operation, or up to 70,000 hours. Frames and drawers are guaranteed against deformation and mechanical degradation. In the event of abnormal breakage within 2 years, we analyse the aggressive parameters together to enhance robustness.

Q: Can our existing emitters be replaced by Sopara emitters?

In most cases, yes. We carry out retrofit operations on existing installations, including on emitters not originally from Sopara. We analyse your installation, identify the emitters to be replaced and propose an adapted solution, often with significantly improved performance. We also provide maintenance on these installations. Contact us with the references of your current emitters.

Q: Up to what temperature can you heat?

Up to 500°C depending on the range. Our MIR HP emitters integrate high-resistance ceramic frames that enable these levels to be reached with inertia under 5 seconds.

Q: Can you work in all orientations?

Yes. Our emitters are designed to operate in all positions : horizontal, vertical, inclined — to adapt to all parts, your processes and space constraints.

Q: Can you process products containing solvents?

Yes. We precisely calculate the extraction flow rates required to maintain solvent concentration below one quarter of the Lower Explosive Limit — the threshold that allows operation outside ATEX classification.

Q: Can you intervene remotely on an installation?

Yes, via modem and VPN when an electrical cabinet is present. Remote diagnostics and adjustments without site visit.

The Best Emitters on the Market

If our RadiantLine™ emitters are so high-performing, it is because we are far more than manufacturers. Every emitter has been designed by engineers who are experts in thermal science and industrial processes. The only French manufacturer to master and produce all three infrared wavelengths (short, medium and long) — electric and gas — our emitters are developed under an ISO 9001 certified process that guarantees their quality.
For over 30 years, they have equipped the R&D laboratories and production lines of the largest OEMs in composites, paint and textiles.

Patent Filed — World Innovation

The Aero V5 Pushes the Limits of Infrared Heating

For 20 years, heating thermoplastic composites with complex shapes and variable thicknesses with perfect homogeneity was impossible. Conventional emitters generated peripheral cold zones, visible temperature gradients, out-of-tolerance parts. Unacceptable for aerospace.

5 years of iterative development with leading industrial manufacturers. The MIR HP Aero V5 is the result: a patented emitter that reaches 450°C with a precision of ±10°C and homogeneous heating across the entire surface, regardless of the shape or thickness of the part. A technological leap that can benefit every sector.
