Active ionizers

Product catalog summary
Introduction to Electrostatic Charges: The document begins by explaining the origin of electrostatic charges, traditionally attributed to friction (tribo-electricity), but now understood through semiconductor physics. When two materials come into contact, electron migration occurs due to differing electron work functions, creating a voltage at the Helmholtz double layer.
Ionizers and Static Electricity: Ionizers are devices used to manage static electricity, which can occur in both insulators and ungrounded conductors. Static electricity is common in nature and industrial processes, such as in the textile and plastics industries, where it can cause operational issues.
Functioning of Active Ionizers: Active ionizers, particularly those using alternating current, are described. These devices generate ions to neutralize static charges on materials. HAUG ionizers are noted for their safety features, such as galvanic separation of pins from high voltage.
Interference from Electrostatic Charges: The document details the problems caused by electrostatic charges in the textile industry, including thread breakage and fabric handling issues, and how ionizers can mitigate these problems.
Types of Ionizers: Both passive and active ionizers are discussed. Passive ionizers use metallic tips to induce corona discharge, while active ionizers use high voltage to generate ions. Air-assisted ionizers extend the range of ionization by using compressed air to transport ions.
Measuring Static Electricity: Methods for measuring static electricity are outlined, including the use of field strength meters and modulation measuring units, which operate without contact to assess the electrical field's magnitude and polarity.
Applications and Products: HAUG offers a variety of ionization systems, including air-assisted ionizers and web cleaning systems, which are crucial for maintaining material cleanliness in industries like paper and textiles.
Conclusion: The document concludes with a brief overview of HAUG's product offerings and contact information for their global offices.
