Energy-Electric IR Drying Tunnel | Zone-Controlled Heating for Heat-Sensitive Substrates
Product Overview

This industrial infrared drying line uses medium-wave or short-wave IR emitters to rapidly transfer energy into coated or printed substrates without heating the surrounding air. Drying times are reduced by 50-80% compared to conventional hot air ovens. The modular design allows integration into existing printing, coating, or laminating lines. Customizable emitter type, zone length, lamp power density, and cooling method available for different substrates (paper, film, metal, wood, textile, or glass).

Applications
  • Printing industry - solvent-based, water-based, UV inks on paper, film, foil
  • Coating lines - varnish, lacquer, primer, adhesive on wood, metal, plastic
  • Textile drying - pigment printing, resin finishing, screen print curing
  • Electronics - solder mask drying, conformal coating curing
  • Packaging - lamination adhesive drying, carton coating
  • Automotive parts - primer flash-off, topcoat drying
  • Nonwovens & fiberglass - binder curing, moisture removal
  • Wood finishing - stain, sealer, topcoat drying on panels or profiles
Customization Options
  • IR wavelength selection - short-wave (fast heating, thick coatings) or medium-wave (gentle, deep penetration)
  • Zone length & number - from 0.5m touch-up dryers to 20m multi-zone tunnels
  • Emitter layout - horizontal (web), vertical (sheet), or angled (3D parts)
  • Cooling system - ambient, forced air, chill roll, or water jacket
  • Explosion-proof design - for solvent-rich environments (ATEX/CSA optional)
  • Air purge system - to prevent dust/condensation on emitters
  • Heat recovery unit - recirculates exhaust heat back to upstream processes
  • Profile control - edge-to-edge power zoning for uneven coating thickness
  • Integration - with printers, coaters, laminators, or slitters (customizable interface)
  • Substrate tracking - width & speed compensation (sensor feedback)
Key Features
✅ 50-80% faster drying vs. conventional convection ovens
✅ Energy efficient - energy directed to substrate, not ambient air (up to 50% savings)
✅ Compact footprint - 1/3 to 1/2 length of hot air tunnel
✅ Instant on/off - no warm-up or cool-down time
✅ No air turbulence - ideal for lightweight webs (film, tissue)
✅ Zone power independent control - perfect for variable coating weights
✅ No moving parts inside hot zone - low maintenance
✅ Suitable for heat-sensitive substrates - medium-wave IR with pyrometer feedback prevents burning
✅ Safe operation - lamp break detection, over-temperature cutout, fume extraction interlock
Support & Services

  • Port of shipment: Shanghai / Ningbo / Shenzhen (customizable)
Frequently Asked Questions
Q1: What is the difference between short-wave and medium-wave IR for drying?
A: Short-wave (0.8-1.4 μm) heats the surface instantly - ideal for thin coatings, high line speeds, and water-based systems. Medium-wave (1.4-3.0 μm) penetrates deeper - better for thick coatings, adhesives, and heat-sensitive substrates. The wavelength is customizable based on your material.
Q2: Can an IR dryer be added to my existing hot air drying line?
A: Yes. Many customers use IR as a pre-dryer (flash-off) before the hot air oven, reducing total length. Retrofitting is customizable - we provide mounting brackets and control integration.
Q3: How much energy can I save compared to my current gas hot air dryer?
A: Typically 30-50%. IR transfers energy directly to the substrate without heating large air volumes. A free test with your material gives exact savings.
