1. It adopts imported thermostat control which owns fuzzy control and PID intelligent precision control system.It can fast
response the changes in external heat and ensure more temperature balanced by PID intelligent operation and automatic
control heating .
2. Using thermocouple imported from Taiwan by each temperature zone, it can fast and sensitive induct the changes in each
temperature zone, transfer and control timely, compensate the temperature balance in each zone.
3 .Special SSR solid state relay matched with dedicated radiator improve the heat efficiency greatly and prolong the lifetime
effectively. No contact output and fuzzy control function by thermostat, can monitoring the changes of outside temperature
and calorific value, controlling the heating device by minimum pulse, ensuring the high precision of the temperature control &
the uniform temperature in internal and the length ,direction, temperature distribution, all of these meet IPC standards .
4. Power is abundant, heat up fast, it’s only need 20 minutes from room temperature to constant temperature.
5 .Failure diagnosis and sound light alarm.
6. Delay shutdown production function, uniform cooling after the shutdown: prevent component deformation.
