There is not ONE single killer-product solving all the different electrostatic problems in the manufacturing processes. Within our carefully assembled prouct portfolio you will for sure find THE solution to your problem. We have categorised the products according to the following criteria:

  1. required residual charge
  2. area to be discharged
  3. air support/cleaning
  4. power supply, location of HV generation

Our domain experts are happy to analyse your specific problem on-site and advise you on possible solutions.

The work processes described in Your Problem often generate static charges of in average 30 KVolts and can range up to 50 kV depending on material(s) and procedure.

If only static sparking and/or impact on personnel (i.e. electric shock) shall be prevented, it may suffice to reduce the largest part of the charge through so-called passive ionisation – see graph. Passive systems lead the charge via grounded tips or fibres away, also contactless.

Although the attainable residual charges are for human-beings no more perceptible (app. still disrupt production processes through adhesion, blocking or dust attraction (from app. 1 kV), or can even damage electronic components (MOS/CMOS components from 50-80 V onwards) which is called ESD.

Attainable Residual Charges

Attainable Residual Charges

That is the reason why usually an active discharging with electrodes, ionising air nozzles or ionising air blowers is necessary: via high-voltage a specific “counter-charge” is generated, with the effect to ionise the air at the tips of the electrode and thus neutralise the charge at a distance of 30-1500mm to the object without direct contact. In this manner it is possible attain residual charges of +/- 10 V.
