The "NANAO IP-ZERO Fe" is a cartridge exchange and regeneration type iron ion removal device for acidic plating solutions. It significantly improves the time until the plating solution needs to be replaced. After using the plating solution to a specified Fe concentration, you can choose to remove Fe ions in a separate process using this product. 【Features】 ■ Compact device that does not require much installation space ■ Continuous removal of Fe ions ■ Maintains low Fe concentration over a long period ■ Allows selection of the specified removal operation time to reduce Fe concentration below the reference value *For more details, please refer to the PDF document or feel free to contact us.

"NANAO IP-ZERO" is a device developed for the purpose of removing nickel ions, which are impurities in acidic gold plating solutions. When applying partial gold plating to nickel-plated materials, nickel dissolves in the gold plating solution, adversely affecting the properties of the gold plating layer. Researchers at Nanao Industry have established a technology that separates and removes not only nickel ions but also iron ions by combining multiple separation techniques. 【Features】 ○ Can remove 99% of nickel, which is mixed in as an impurity in acidic gold plating. ○ Gold compounds remaining in the device are cleaned and recovered to be returned to the gold plating tank. ○ The plating solution after removal has no impact on the plating process. → Tested in plating factories. ○ Significantly reduces the time required for plating solution regeneration. → Prevents funds from being frozen for a certain period, improving capital turnover efficiency.
