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).

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.
