8 Zones Nitrogen SMT Reflow Oven KTE 800-N

Features:
1. Totally meet various requirements for the lead free processing.
2. WindowsXP operation system, Chinese/English can be swtiched online.
3. Standard air oven, Patent air system, using hot air convection conduction heat faster, more efficient compensation.
4. PLC+PID closed loop control to achieve high prectise temperature control and repeatable profiles.
5. Dual temperature sensors and dual safety control, system shall cut off the power while abnormal alarm.
6. Modular design to get quick and simple maintenance so that reducing the maintenance time & cost.
7. The temperature inspection instrument constantly monitors the temperature of each temperature zone, ultra-high temperature protection, and automatically switch off the heating power
8. Nitrogen quantification is controllable throughout the process, and each temperature zone is independently closed-loop controlled, which can make the nitrogen concentration range from 5-200ppm.
The new two-stage flux recovery system, multi-point collection, fully improves recovery efficiency and reduces maintenance time and frequency for customers.
