E3633 Reactive Antistatic Power-Bar
The ultimate Power Pack on the market for very demanding distances.
Operating range: 250 – 1000 mm Best use where large distances (up to 1,5 meters!) and strong discharge performance without air supply are required (e.g. large winders, turret winders, large objects on conveyor belts etc). With 33 kilovolts output under load, the E3633 is the strongest and most efficient wide-range antistatic bar in the market. Furthermore, it intelligently adapts itself to the load via built-in determination of the electric field.Application

Electrostatics
Electrostatics in Industry
How it is generated and what you can do about it
Below we describe how the charge is generated. It explains the way that occurs most often in industry: electron displacement by contact and separation. There are other possibilities such as strong radiation, influenza etc. We will not go into this.
Almost all substances have electron shells at the extreme atomic and molecular level, which have a relative electron excess or shortage.
Thus, when surfaces touch, an automatic electron transfer takes place to the electrostatic equilibrium.
During the separation process, depending on the (separation) speed, electrons cannot return but are “torn away”.
As a result, an electron is missing in one place, while it is too much in the overall balance at the new place: positive AND negative charge islands arise, regardless of whether a substance is conductive or not.
An insulator is neither through the material…
…nor dissipative on / over the surface i.e. the charge does not flow off and remains.
The electrical charge remains in place, i.e. is static -> electrostatic
Grounding is useless.
As with all materials, also with conductive and grounded materials an electron transfer to electrostatic equilibrium takes place at the contact surfaces.
Depending on the speed, electrons are also left behind during the separation process.
While an insulator (upside) remains charged, the conductive body (below) e.g. metal roller can simply discharge towards earth.
But electrostatic charge at the insulator (top) e.g. plastic foil is not avoided -> dissipative and grounded machine parts do not prevent electrostatic charge on the material!
Air molecules are charged with antistatic bars: high voltage is applied to sharp tips, which ionises the air, i.e. the air picks up the charge.
The ions are attracted by the opposite charge on the material surface and migrate there (up to 1500mm without additional air support).
The air exchanges the charge on the surface and neutralises the surface almost completely.
The ionization takes place in a pulsed manner – plus and minus are never generated simultaneously, but are clocked.
No surface is really smooth, but the air molecules reach “mountain and valley”.
In passive systems like antistatic brushes, many mandatory grounded fiber tips are brought very close to the material and also work with ionised air.
The passive ionisers discharge the material through a very narrow air gap due to the electric field, which builds up naturally against earth.
However, this physical effect breaks off at a certain field strength, as a consequence a passive ionizer does not reach a low residual charge, we are not talking about neutralisation here. The discharge is just enough to avoid sparks and shocks to operators, but rarely to avoid adhesion (e.g. dirt, other materials etc.) or repulsion (e.g. ink droplet misprinting or telescoping of foil).
Intelligent Antistatic Bars
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:

24VDC Technology
24 VDC Technology explained
In mechanical engineering, 24 V DC has become the de facto standard in measurement and control technology and other components for decades. So it was only natural to look for ways to develop ionizers that can be connected to the almost always available 24 VDC supply.
Last generation ionisation systems get the required high voltage by transforming the 230 V AC and 50 Hz mains voltage.
What is new?
- Antistatic bars have the highvoltage generation integrated
- Later is integrated in a very compact way directly into the bars casing
- The bar is directly fed with 24 V DC (direct current)
- The bars supply can be taken from the machines 24VDC net
- Each ioniser informs about its operation and shows an alarm when it is contaminated
- They all have a simple interface for communicating with controls
The following advantages result
The size of the corresponding standard AC bar is identical with the DC bar
- take old AC bar out, put new DC bar in
Rigid and fragile highvoltage cables are no longer required
- Lightweight DC cables suitable for drag chains
- Trouble-free connections
Neutralising over distances greater than 100 mm have not been possible without air support, since you are no longer tied to the 50 / 60Hz of the power grid.
A separate high-voltage power supply is no longer required
- the space for the extra case is obsolete
- the limitation with cable length per power supply unit no longer applies
Easy and comfortable supply with 24 VDC
- almost every machine offers 24 VDC
- International kein Problem mit V/Hz da DC und Beinahe-Standard 24V
The performance is in average 20% higher
- 7,5kV or more instead of 5,5kV
- no sinus- but square-shaped highvoltage curves
Iontis and Fraser are among the pioneers in 24VDC technology. We offer since 2009 24 VDC ionisers with integrated highvoltage generation and do have today the most comprehensive portfolio and the most sophisticated products
