Charge wire
Luma tungsten wire is used as charge wire in several different application areas. Supplying high quality wire made by different raw materials and with different surface finishes, Luma is a highly appreciated supplier to manufacturers working within this application area.
As the charge wire is exposed to high voltage and expected to give precise results for repetitive cycles; Luma tungsten wire is a popular material due to their high strength and durability.
A charge wire is used to create a field of positive and negative charges. These charges create an electrostatic field used in for example digital printers, air cleaners and electrostatic separators.
Luma tungsten wire
Depending on type of application the choice between raw materials, for example Luma tungsten wire differs. But also the surface finish, such as clean, oxidized or gold plated.
Below are some examples of application areas using Luma wire as charge wire.
Luma supplies wire which is used as corona wire, generating fields of positive charges in large digital printers. Tungsten wire is a reliable and cost-effective alternative for repetitive cycles of charge and discharge. The tungsten wire is exposed to a high voltage which puts high demands on its durability and strength. Mostly Luma gold plated tungsten wire is used. But also cleaned and oxidized wire is supplied for this application area. Luma tungsten wire with a gold plated surface is the most common alternative. The gold coated surface reduces defects and enhances the print quality as well as lifetime. The gold coat also prevents corrosion.
Air ionizers / Negative ion generator
Luma supplies wires to manufacturers of air ionizers. An air ionizer or negative ion generator is a device that improves the quality of the air in its environment. By using high voltage to charge air molecules it attracts airborne particles. The most common design generates negative ions. The positively charge particles are attracted to the ions similar to static electricity and then passed through a filter. Besides the usage for example in hospitals where the air environment is of most importance. Ion generators are also used in manufacturing facilities to minimize static electricity or contamination of dust particles.
