Ionisering
Ionizers should be considered as a method for charge neutralization in cases where grounding cannot be achieved. These may include localized (bench) ionized air blowers, compressed air ionizers, spot ionizers, tape dispenser ionizers and total room ionizers.
Air ionization can neutralize the static charge on insulated and isolated objects by producing separate charges in the molecules of the gases of the surrounding air. When a static charge is present on objects in the work environment, it will be neutralized by attracting opposite polarity charges from the ionized air.
Note that ionization systems should not be used as a primary means of charge control on conductors or people. As with all ionizers, periodic maintenance will be needed to provide optimum performance (EN 61340-5-2 paragraph 5.2.9).
"Various feedback and auto balance techniques are available to ensure ionizer performance. … Providing a sensor for each ionizing device can improve feedback control. Effective control can reduce the amount of necessary maintenance." (EN 61340-5-2 paragraph 5.2.9.2 Monitoring and feedback control)
