Full hot air lead-free reflow Oven with 7 heating-zones TN370C
Product instruction of TN370C:
Heating system: TN370C adopts high effective and energy-saving nickel-chromium heating tube. Advanced technology and Long life. And TORCH self-developed hot-air circling system features warm up quickly, which can make PCB component be heated evenly.
Protection system: TN370C uses SSR solid relay (450V) that has large power and pressure prevention to non-contact output, safe and reliable. It can monitor the change of temperature and heat number in furnace chamber with the functions fuzzy control and data collection. Then control the heating component with the least pulse and response quickly. TO keeps the Temperature control accuracy, but the equipment can not be damage for the high current and high voltage. And each room fits a safety pipe which is high temperature and high pressure resistant function so that the whole system can run safely and calmly.
Accuracy control by IPC and PID intelligent arithmetic. According to the PID intelligent calculation, heat output can be controlled accurately and response to the change of outside to balance the temperature. The whole system has a modularized design. It is convenient to maintenance and disassembles
Outer shell and furnace body of TN370C can be opened wholly and automatically. It is convenient to clean and maintain it.
Main features for TN370C:
1> Intuitional welding control: TN370C adopts advanced furnace temperature collection system. It can test temperature curve and temperature in furnace hearth. The temperature curve can be recorded or printed at the same time.
2> Smooth and safe transmission system: Drive system adopts a high quality conversion motor and conversion system. It also has a closed-loop governor and Turbine speed reducing box of 1: 100 to keep running smoothly
. Speed: 01600mm/min.
3> Stable and safe electric control system: Delay switch protection. After power off, temperature drops evenly so that can prevent damage to transmission component and heater.
4> Power-off protection: To keep PCB output normal. Windows operating platform has a strong functions and high stability.
5> Upper and lower heating zones are separately controlled. The circulation speed can also adjust separately. It is suitable for welding different PCB plates and components.
