Lead-free Nitrogen Reflow Sodering Machine

HW-800N is a lead-free nitrogen reflow oven, offering 8 heated zones (8 top & 8 bottom side) and 3 chilled air-cooling zones, can handle all high-volume manufacturing requirements. Backed by our 2 years warranty and high quality after sales service. It's the safe choice for customer requiring no compromise quality, reliability, and exceptional value for cost.

Lead-free Nitrogen Reflow Soldering Machine HW-800N/HW-800N-D(dual rail)

We have a full range of oven ranging from 8 to 12 zone, from nitrogen to hot air versions, please contact us to discuss your individual requirement.

95% of the material on the machine can be recycled.
Strengthen the main boom to ensure the guide rail lateral deformation, to eliminate the board jamming and dropping.
Multi-layer heat preservation furnace chamber design, effectively reducing the temperature by 10-20 degrees of the furnace surface temperature.
Option: dual rail. Dual-rail structure effectively improves production efficiency and saves energy and production cost.
15% improvement in heat transfer efficiency, to cope with more complex and large welding products lead-free process requirements.
New cooling structure design allows most of the exhaust gas to be filtered or recycled and returned to the furnace, which reduces heat loss and makes flux recovery more complete.
The nitrogen can be as low as 150PPM. Only 20-22m&sup3/H in 300-800ppm oxygen concentration environment.
Inline operation with SMEMA communication.
