How to choose a static control device
There are many factors to consider when choosing a static eliminator. Here are a few of them:
Distance from the material:
Some static eliminators are designed for short range operation, others for longer range. As a general rule choose a short range static eliminator if your application allows this. Short range static eliminators are lower in cost and usually more effective.
There has been a revolution in the performance of static control equipment. It started in about 2004 with the launch of the Fraser Ionstorm long range static eliminators. Since then advances have been rapid. The modern DC powered static eliminator is many times better than older equipment with separate high voltage transformers. Older designs still may be adequate for many applications, but it is unwise to base a purchase just on cost. Modern DC static eliminators may be 10% more expensive, but they provide up to 100% more power, with many other advantages.
Some static control solutions cost more than others, while some deliver greater value in multi bar applications. There are passive static control solutions which cost far less than powered static eliminators however they are not suitable for a large number of applications. It is tempting to try and save money by extending the range of an ioniser by incorporating air to push the stream of ions further, and while this works well in certain situations it is not as effective as a powerful purpose built long range static eliminator.
A good rule of thumb when considering the true cost of static control systems is to also consider the substantial savings achieved by faster production speed, less product rejection, improved safety and overall quality gains.
