Different types of Static eliminators
Static electricity can be troublesome in many production processes where non-conductive materials such as plastic, paper, wood and textile are processed. Specially during the winter months when outside humidity is low and inside the air is dry, static can cause many problems. In many processes like printing or a coating process static needs to be eliminated for safety and quality purpose. The removal of static can be of major importance if production processes work with isolated (non-conductive) materials.
(high) static charges can result in production problems like:
- Restriction in machine production speed
- Undesirable attraction of dust and particles
- Unwanted electrical shocks to production employees.
On the market are two ways to remove static electricity: the passive and the active method. If the static has to be removed in a professional and controlled manner modern industry is choosing nowadays for the active method. Active removal of static electricity is done with high voltage ionisation equipment. This equipment produces positive and/or negative ions to remove static electricity from your products. If your product is negatively static charged it will attract positive ions and when charged positively it will attract negative ions.
Simco-Ion Europe has been developing and producing this ionisation equipment for over 60 years now. In our products program you will find several product for the removal of static like: Ionisation-bars (AC and DC), -air nozzles, -air blowers, -air knives and -power units.
A static charge remover needs to be used to solve the problems. There are many different Static eliminators produced by Simco-Ion Europe differentiated by the different applications, the way to operate or the place where they can be mounted or put. Please click on the link of the different types to find the right type of static eliminator for your application.
Simco has developed different industrial in-line ionizers to neutralise static charges on materials in pneumatic conveying systems. When non-conductive materials are processed through an air operated tube system, they often contain a static charge due to earlier processes. As the material is transported through the tube, it will generate an even higher static charge. An in-line ionisation system prevents clinging and clogging of material in the tube systems because of this generated static electricity. Considerable costs and time are saved by preventing machines from stopping due to maintenance and cleaning tube systems.
Simco offers the Conveyostat in-line ionizer for larger diameter tubes. It is typically mounted vertically and at the input to a cyclone or collection vessel. The Conveyostat exists of a stainless steel tube with at least 2mm wall thickness. Depending on the diameter of the tube, multiple static eliminator bars are integrated in the tube and connected to a dual phase power supply. The conveyed materials are charged during transport in the tube, but then neutralized as they pass through the unit.
A second in-line ionisation solution from Simco is the compact Blowflex in-line ionizer. This is a static solution well suited for applications with limited space or when the material is difficult to access. The Blowflex in-line ionizer can be used in combination with multiple nozzles, tubes or air rings.
Each in-line ionization solution is custom made and created together with a static specialist. For more information on in-line ionizers or technical advice, please contact Simco-ION.
Long Range Static Elimination
Static elimination is the process of directing a flow of negative and positive particles towards a charged object. The polarized particle on the surface of the object recombines with the directed opposite particles. This reduces the static electricity on the object and so “eliminates” the static charge on the object. Normally static eliminators need to be close to the object in order not to lose efficiency. Efficiency is lost when travelling polarized particles recombine before reaching the object. Longer distances can be reached by means of specialized static eliminators or air-supported static eliminators. Long range static elimination can be achieved by means of the following products:
- DC Long Range Static Eliminator
- AC Long Range Static Eliminator
- Ionising Blowers
- Ionising Guns
- Ionising Airknives
Short Range Static Elimination
Short-range static elimination is the placement of a static eliminator very close to the material that needs to be neutralized. This normally is needed to keep external influence to a minimum. Also smaller machines have limited space to create negative and positive charged particles. The particles are directed and reach the object instantly for the process of neutralization. The static eliminators found here are normally very small in size and mostly powered by an external high-voltage power supply. Short Range static elimination can be done with the following equipment:
- DC short-range static eliminators
- AC Short-range static eliminators
- Ionising Blowers
- Ionising guns
- Ionising Air-knives
- Ionising nozzles
- Inline-Ionising equipment
- Table Top Ionisers
Static Neutralizing Systems
Static electricity is the presence of an electrical voltage in a non-conductive material. The charged particles therefore are not able to move. Normally in conductive materials Voltage differences will create a current to let access in charged particles flow to the earth when grounded. Static Electricity however can not flow to the ground since the molecules and ions can not move around in the material that they are present. Static electricity therefore can only be neutralized by a static neutralizing system. Static neutralizing systems send opposite charged particles to the object that needs to be neutralized. The charged particles will recombine with the charged object until there is no Voltage difference left. The object then will be neutralized. Static neutralizing systems can normally consist of different static eliminators.
