Desco Europe Overhead Ionisers

Ionisers are useful in preventing electrostatic charge generation, ElectroStatic Discharge, ElectroStatic Attraction, as well as preventing equipment latch-up.


"Ionizers are used when it is not possible to properly ground everything and as backup to other static control methods. In clean rooms, air ionization may be one of the few methods of static control available." (ESD Handbook ESD TR20.20 Ionization, section 5.3.6.1 Introduction and Purpose / General Information)


Overhead Ionisers produce extended ionisation coverage and are ideal for areas where bench space is limited.


Our Overhead Ionisers use steady state DC ionisation. Experience has found that steady state DC ionisers work effectively with a modest airflow suitable for sensitive items, soldering operations, and where operator comfort is a concern.




Chargebuster Overhead Ioniser The Chargebuster Overhead Ioniser is a steady-state DC ioniser for use in ESD sensitive work areas. The specially designed 3-speed fan modules create better coverage, consistent offset voltage and superior discharge times. The Ioniser is equipped with an Auto-Feedback system that continuously optimises the performance and will automatically shut down and alarm if the supply voltage should drop.
