Electrostatic Systems

Electrostatic systems - Static electricity examples

Whether too small to see or a bolt of lightning, the spark is a typical phenomenon that accompanies electrostatic discharges. Renmar has the know-how and the engineering skills to measure, control, eliminate and utilize these elemental forces.

Electrostatic systems

Eltex are not just the solution to the problems and risks of static electricity, but also offer immensely practical ways to overcome undesirable side-effects of a variety of manufacturing processes. Through the years, Eltex has continuously invested not only in applied research and development but in basic electrostatic energy research, as well. The functional and application knowledge thus gained is invested into the hardware and software that Eltex provides to its customers. The hardware is technology for measurement and control, charging and discharging. The software is complete electrostatic solutions.


The capability to accurately measure electrostatic charges (including high voltages, electric fields and high resistances associated with charge-carrying materials) provides information basic to eliminating disruptive, undesirable electrostatic energy.


Uncontrolled electrostatic discharges are a matter of great concern in many areas of production and transport, above all, in sectors where highly flammable materials are handled. Spontaneous discharges can cause explosions, deflagrations or fires.


In spite of grounded machine frames, contact and separation steps can still cause electrostatic charges which cannot leak off through grounding connections. For these cases Eltex has developed systems in which active and passive discharging are linked, guaranteeing the ultimate in safety and efficiency.


The same “clinging” attraction that is so undesirable when caused by spontaneous static charges, can become highly desirable when used in a controlled way. For instance, stacks of paper or plastic materials can be virtually “glued” together by including opposite charges. Electrostatic charging systems use this phenomenon to temporarily “bind,” block or tack certain materials electrostatically.

This type of temporary electrostatic bonding can be used with many different kinds of materials. There is no contact with the material and there is no residue. The grip of the bonding force is stable for the duration of a work cycle. Although the materials can be released at any time by specifically discharging them, the electrostatic charge will wear off on its own. In either case, the materials remain in perfect condition.
