The ERSA HOTFLOW 3/20 XL Reflow Soldering Oven is a high-performance convection reflow system specifically engineered for manufacturers processing large-format PCBs, high-density assemblies, and demanding lead-free soldering applications. As an advanced member of the renowned HOTFLOW series, the 3/20 XL combines intelligent thermal management, exceptional temperature uniformity, and high production efficiency to meet the requirements of today’s automotive, industrial, telecommunications, renewable energy, and power electronics industries.
Designed with 20 independently controlled heating zones and an extended heating chamber, the HOTFLOW 3/20 XL provides highly accurate thermal profiles for oversized circuit boards while maintaining outstanding solder joint consistency. Its optimized forced-convection technology ensures even airflow across the entire PCB surface, minimizing temperature deviation and significantly reducing soldering defects such as voids, tombstoning, insufficient wetting, and PCB warpage.
The XL platform is particularly suitable for manufacturing products that require larger PCB dimensions, including EV power modules, industrial controllers, communication backplanes, LED lighting systems, and energy storage electronics. Advanced process control software enables operators to create, store, and optimize multiple thermal recipes, ensuring fast product changeovers and highly repeatable production quality.
Energy efficiency remains a core advantage of the HOTFLOW 3/20 XL. Intelligent airflow management, premium insulation materials, and optimized heating modules help reduce electricity consumption while maintaining outstanding thermal stability. The system fully supports lead-free and conventional soldering processes, making it suitable for a wide range of global manufacturing standards.
Every refurbished ERSA HOTFLOW 3/20 XL supplied by Fuliu undergoes comprehensive refurbishment, including heating module inspection, blower balancing, conveyor alignment, thermal profile verification, electrical diagnostics, software testing, and full production simulation. Fuliu also offers turnkey SMT production line design, installation, commissioning, operator training, spare parts supply, preventive maintenance, and lifetime technical support, enabling manufacturers to maximize production reliability while minimizing capital investment.
