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.
