IR & RF Dryers for industrial

Low-heat electrification using infrared (IR) and radio-frequency (RF) dryers can reduce drying energy and emissions by 40–70%, improve product quality, and reduce footprint—making them essential decarbonization tools in sectors like food, textiles, chemicals, and ceramics.

IR Dryers: Fast surface heating, compact, good for lower-moisture or surface drying tasks.

RF Dryers: Volumetric heating ideal for thick or moisture-heavy materials, offering high efficiency and quality retention.

Hybrid IR/RF/HA systems deliver the best energy and performance balance but require careful engineering.

Emissions & Efficiency

• IR dryers offer quick, direct heating with lower energy use versus convective methods.
• RF systems deliver up to 75% energy efficiency, versus ~15% near-IR or 5% hot-air efficiency in some coating processes.
• Combination approaches (hot-air + RF) can slash drying energy by >40% and reduce drying times by ~60%.

Supply Chain & Deployment Challenges

• System costs: Capital-intensive, especially RF; payback depends on downstream savings and product quality.
• Process integration: Requires custom electrode design for product shape, plus safety systems and control electronics.
• Hybrid complexity: Combining RF with hot-air or IR adds control complexity, but yields optimal performance.
