Intelligent Antistatic Bars
Antistatic bars adapting automatically to polarity, charge amount and distance of the material
In general, we always try to deliver a large excess of ions with the electrodes. We always have to take both possible polarities into account by changing several times per second the polarity of the ion emission. If you are able to be close to the material with the ioniser, standard bars can work efficiently in this manner.
However, there are applications where the distance and / or the material often change during use e.g. bulky parts on a conveyor belt, web on rollers and winders etc. There it can be beneficial to control and adjust the time allocation of positive and negative ion emission.
In the case of unwinders, for example, charge islands of both polarities form inhomogeneously on the material. Adjusting the ion output of the corresponding polarity can be advantageous here, also because the antistatic bars must act over a large distance range and are therefore also clocked more slowly.
Based on the current power requirement, our electrodes detect the current electric field and thus adjust the ion output to the corresponding opposite polarity fully automatically in order to adjust the discharge results. However, ions of the other polarity are always generated in order to neutralise charge islands of the other polarity as well.
We offer the following intelligent antistatic bars:
E5000 – The Swiss Army Knife
The E5000 was brought to the market in 2009 offering the following patented and clever control mechanism:
- Distance automation/frequency adjustment
- Automatic ion balance
- Contamination alarm
- Gradual display of contamination of conductive AND non-conductive contamination
E3633 – Reactive Power Bar
The E3633 was recently introduced to the market and is simply the strongest and most efficient bar. It offers the following sophisticated control:
- Automatic polarity adjustment
- Automatic ion balance for 4 ranges
- Contamination alarm
E3420/E3412 – Reactive Highperformance Bars
The wide-range bar E3420 and the midrange bar E3412-L as well as its sibling for fast web speed the E3412-F offer the floowing control mechanisms:
- Automatic polarity adjustment
- Automatic ion balance for 3 ranges
