Introducing the JTR Series Lead-Free Hot Air Reflow Oven, equipped with advanced features for enhanced efficiency and performance. The oven includes a reinforced main hanging bracket to prevent rail deformation and board jamming. Its multi-layer thermal insulation design reduces the oven body surface temperature by 10 to 20 degrees, effectively lowering the working environment temperature. A new cooling configuration redirects filtered or reclaimed air back into the oven chamber, reducing thermal loss and improving flux collection. Furthermore, the oven boasts a 15% improvement in heat transferring efficiency, specifically designed to handle lead-free processes and larger, more complex products. Its dual-rails conveyor system increases production efficiency, saves power, and reduces costs. With a sealed oven design, nitrogen loss is prevented, achieving oxygen concentrations as low as 150ppm. Optional nitrogen construction features a high-precision, reliable Oxygen analyzer and cooling water system, ensuring reduced solder, prevention of bridging, and high-quality welding.
The KT series high-end lead-free hot air reflow oven is designed for high-speed production and high-density PCBA technology. With a high capacity and a normal working conveyor speed of 160 cm/min, this oven ensures low energy consumption and cost efficiency. Its powerful temperature control maintains a setting and actual temperature difference within 1.0°C, and the load and unload temperature fluctuates within 1.5°C. Rapid temperature raising capability allows for a 100°C difference between neighboring zones. This oven employs the latest insulation techniques and chamber design, ensuring the surface temperature is only 5°C above room temperature. Nitrogen volume is controllable throughout the process, while oxygen density is independently controlled in a closed-loop system at 50-200 ppm in every zone. Advanced cooling technology, with optional double-sided multi-cooling zones and an effective cooling length of 1400 mm, ensures fast cooling of the product to the lowest output temperature. The KT series also features a new two-level flux separation system with multi-point collection, thoroughly separating flux and significantly reducing maintenance time and frequency. Its dual-line system operates at different speeds, offering double the capacity at one set cost and saving 65% on energy consumption.
