8 Zones Nitrogen SMT Reflow Oven KTR 800-N

Features:

1. Reinforced main hanging bracket to guarantee there is no deforming and board jamming occurred.

2. The dual-rails conveyor is able to improve the production efficiency as well as power & cost.

3. 15% heat transferring efficiency was improved to deal with the lead free process with more complicated and larger products.

4. New cooling configuration to make the filtered or reclaimed air back to oven chamber, it reduced the thermal loss as well as get better flux reclamation.

5. User the full protection of the sealed oven design to prevent N2 and O2 from losing effectively. So the lowest concentration of N2 and O2 can be reached to 150 PPM.

6. When Concentration of oxygen is 300-800 PPM, consumption is only 20-22M3/H.

7. 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.

8. The new two-stage flux recovery system, multi-point collection, fully improves recovery efficiency and reduces maintenance time and frequency for customers.
