| Lyra Series Professional Nitrogen Reflow Oven


As one of the most experienced nitrogen reflow oven manufacturers in China, I.C.T launches the Lyra series Nitrogen Reflow Oven – the ultimate Nitrogen Reflow Soldering Oven and reflow oven machine for high-reliability SMT lines. Fully sealed chamber with intelligent nitrogen recycling maintains ultra-low oxygen from preheat to cooling zone while consuming the least nitrogen worldwide – real factory data proves zero change after years of continuous running. Widely used in automotive, medical, 5G, aerospace and smart electronics, the Lyra Nitrogen Reflow Oven is the perfect Nitrogen Reflow Oven for SMT Line that delivers shiny, void-free solder joints and maximum yield at minimum operating cost.


| SMT Reflow Oven Features


Unbeatable Nitrogen Protection System

Feature Reflow Oven 01


The Lyra Nitrogen Reflow Oven adopts completely sealed furnace body with minimum openings and smart nitrogen recycling at inlet/outlet. Oxygen concentration stays below 500ppm throughout preheating, soldering and cooling zones with the lowest nitrogen consumption among all nitrogen reflow oven manufacturers – performance remains identical even after 3–5 years of 24/7 production, making it the top choice for oxidation-sensitive Nitrogen Reflow Oven for SMT Line applications.


Premium Heating & Thermal Precision

Feature Reflow Oven 02


High-grade German heating modules and independently controlled hot-air circulation achieve temperature difference ≤ ±1.5℃ and thermal stability >99.99%. Siemens PLC plus industrial PC supports any complex profile with perfect repeatability, turning this Nitrogen Reflow Soldering Oven into essential reflow oven machine for high-density, mixed-technology and heavy boards.


Reliable Transmission & Smart Operation

Feature Reflow Oven 03


Heavy-duty parallel rails with optional central support, wear-resistant chains and closed-loop speed control ensure ultra-stable PCB transport for single-lane or dual-lane production up to 450mm width. The user-friendly Windows software provides bilingual operation, real-time curve monitoring, automatic fault diagnosis, process report generation and maintenance reminders – operators quickly master this Nitrogen Reflow Oven and maintain peak efficiency every shift.
