Patented Innovative Insulation System: Adopt imported dual-layer insulation materials, to ensure the shell’s temperature of reflow oven is not higher than the indoor temperature in normal usage, greatly improving the reflow oven’s heating utilization ratio, power saving 40% than the same type of reflow oven, extremely reducing the electricity cost of reflow oven. Adopt precise PLC + industrial PC control, operating stably to ensure the controlling system zero failure rate. Multi-point air injection principle, the whole micro-circulation structure, up and down heating method, short runofthewind in the heating zones, high heating efficiency.
