MaxiReflow process gas cleaning system for reflow ovens is equipped with cyclone technology. Extracts contaminated process gas from all heated zones, leads it through a cyclone and then directs the cleaned gas back to heating area. The temperature inside the cyclone is controlled. By injecting a small amount of water into the cyclone, both liquid and solid residues are washed off and led into an active carbon filter unit. Is configured as closed system.

Vision series convection reflow ovens have new cooling zone designs. Are effective for the homogenous cooling of large thermal mass PCBs. Cooling area in VisionXP is laid out in 2, 3 or 4 stages. Fans in the individual zones, available with separate speed/volume control, can cool Pb-free processed PCBAs to below 50°C. Bottom-side cooling configuration now available. The design is useful for uniformly processing thick PCBs, workpiece carriers, and PCBs with unevenly distributed copper innerlayers.
