The DARC (Dark-Radiation-Curtain) system by SLF is an advanced inline curing solution for primed or top-coated steel. Unlike standard gas-fired ovens that rely on hot air, the DARC system uses long-wave infrared radiation. This energy is absorbed by the paint and the metal, resulting in ultra-fast "dust-dry" and "handling-dry" states. It is the perfect partner for an automated spray line.
Key Technical Specifications:
Technology: DARC (Dark-Radiation-Curtain) Long-wave Infrared.
Process: Continuous Pass-through (Integrated with roller conveyors).
Energy Source: High-efficiency Gas or Electric Infrared emitters.
Curing Speed: Up to 10x faster than air-drying; 3x faster than traditional convection.
Temperature Control: Precise PLC zoning to prevent over-curing or "burning" of thin sections.
Safety: Integrated solvent vapour extraction and explosion-proof monitoring.
Modularity: Expandable tunnel lengths to suit your specific line speed.
Top 5 "DARC Oven" Advantages:
Drastic Lead-Time Reduction: Go from "Wet" to "Ready-to-Ship" in minutes. This allows for a "Just-In-Time" manufacturing flow where steel goes from the paint booth straight to the semi-trailer.
Massive Energy Savings: Traditional ovens heat the whole room; DARC ovens heat the part. This targeted energy transfer can reduce your gas/electricity bills by up to 40% compared to convection booths.
Recover Your Floor Space: Because the steel dries nearly instantly, you no longer need hundreds of square meters of "drying floor" space. You can use that space for more fabrication or welding bays.
Superior Finish Quality: Fast curing in a controlled tunnel environment reduces the window of time where dust and contaminants can settle on the wet paint, ensuring a cleaner final finish.
Easy Line Integration: The DARC tunnel is designed to sit after your automatic spray booth. It’s a "Set-and-Forget" system that synchronises with your conveyor speed.
