Electrostatic surface charges are common in most coating and laminating operations where insulating (non-conductive) materials are processed at very high web speeds. The static charges cause a myriad of production problems ranging from:
The most dangerous situation arises when a spark from a static discharge occurs in the coating/laminating area, that is saturated with volatile vapors, and ignites a fire. ATEX approved static elimination equipment is required in these environments to neutralise static charges and thus prevent fires. Outside the hazardous area ionising bars and blowers can be used for unwind and rewind stations.
Manager IQ Easy Introducing a new level of static control; the heart of the new IQ Easy platform is the Manager IQ Easy. It comprises of a Control unit with a 7” LCD touch screen, provides information from all the connected devices and makes it easy to change and monitor status and parameters. Up to 6 IQ devices can be directly connected to the Manager IQ Easy. The 24V DC power distribution is routed via the Manager, so no extra cables! This makes the connection of a device even easier than connection to a single desktop power supply.
High performance combined with optimal static control. This is the new standard for antistatic bars. In combination with the Manager IQ Easy the Performax IQ Easy anti-static bar will ensure a very high efficiency of static neutralisation. Within the IQ Easy Platform up to thirty ionisation and charging devices can be connected in a network. Through the Manager IQ Easy it can be set up as a pro-active static neutraliser using the patented Up-stream static charge evaluation technique. Adding a Sensor IQ Easy to the system enhances the efficiency by measuring the downstream residual static charge and regulating the ionisation efficiency in real time to ensure a very low residual static charge. The glassﬁber reinforced proﬁle oﬀers a very rugged structure even up to 5 metres in length. The Performax IQ Easy has an integrated high voltage power supply and requires only a low voltage input of 24V DC. It is equipped with a standard M12 connector for the 24V DC input. Two 3 colour high brightness LED visualises bar ON (green), WARNING (orange) or bar ALARM (red). The Performax IQ Easy bar has light slanted ends and protection classiﬁcation IP66 which allows easy cleaning. Universal mounting brackets are supplied for various mounting options.
A sensor that measures the electrostatic charge of a web can be added to the IQ Easy platform. The Sensor IQ Easy is a bar type device that can hold op to 16 sensor heads. Each sensor head can be placed on a strategical position across the web to monitor the electrostatic charge. All data of each sensor head is communicated to the Manager IQ Easy and stored for process monitoring. For dirty environments or for precautionary protection of the sensor heads, the Sensor IQ Easy bar is equipped with a compressed air connection. Using only a very low pressure and air volume dirt entering the orifice of the sensors is prevented. Anti static bars or charging generators in the system can act on data received from a sensor. This makes it possible to control the static charge level on the web in real time using a closed loop feed back and correction routine. Data received from the Sensor heads can also be used for quality control and process monitoring. It can be retrieved from the Manager IQ Easy through the standard Ethernet port.
