Parameters shown are typical ranges and can be adjusted to your process. Lead time and custom options are confirmed in the technical agreement.

Product Overview

Infrared heating does not rely on air convection; energy reaches the workpiece as electromagnetic waves and converts to heat upon surface absorption. Medium-wave IR (1.4–3 μm) is strongly absorbed by water, coatings, and plastics, making it the common band for drying and softening.

The HYI module comprises a gold-plated or ceramic reflector, halogen or quartz tubes, and an aluminum-profile frame. The reflector bounces back radiation away from the workpiece, raising effective utilization above 70%. Tube surface temperature is 600–900°C and cold-start to full power takes only seconds—ideal for intermittent processes needing rapid switching.

Mounting distance is typically 150–400 mm; closer gives higher power density but poorer uniformity. Side-by-side modules are zoned by workpiece width with IR pyrometer or thermocouple feedback. Solvent-based coatings require exhaust to prevent vapor accumulation near the tubes.
