Static electricity can be troublesome in many production processes where non-conductive materials such as plastic, paper, wood and textile are processed.

How do you know if in your situation static electricity plays a role?

Most common problems are easy to recognise:

Sparks jump over – People get shocks – Materials cling together and are difficult to process – The process is disrupted – Your product attracts dust – Fire is caused (see images below)

What causes static charge?

Static charge is mainly caused by friction and separation of poorly conducting materials.

Static charge can be demonstrated by measuring with an electrostatic fieldmeter.

See the section measuring instruments for possibilities (Sensor IQ Easy, Electrostatic Fieldmeter FMX-004, Static system checker TensION)  or ask us for any further information or advice.

Which method is the most effective to reduce static charge?

Non-conductive materials (insulators) cannot be discharged by grounding.

The most effective and durable solution to reduce the static charge is by active

ionisation. Active ionisation is created by the use of air ionisers. These generate

large numbers of positive and negative ions in the surrounding atmosphere,

which serve as mobile carriers of charges in the air. As ions flow through the air,

they are attracted to oppositely charged particles and surfaces. Neutralization of

charged surfaces is rapidly achieved through this process

What do ionisers looks like and which one is right for my application?

Ionisers are available in different sizes and shapes. The choice depends on the application and a number of distinguishing features:

+ Technology (external power supply, or integrated high voltage 24V)

+ Working distance

+ Material velocity

+ Object to be neutralized, 3D product or flat material web

+ Environmental conditions, temperature, humidity, Atex zone

+ Inspections

Typical applications examples:

Various ionisers:

– Anti-static bars

– Ionising airblowers

– Typhoon

– Ionising airguns

– Ionising nozzles

– Power Units

– Inline ioniser
