An new electrostatic control technology developed by Meech International promises to enable customers to increase their process productivity and profitability significantly. The 977CM Pulsed DC controller is said to provide the first true closed loop static control system - and it incorporates a range of features that make it easier for the user to sustain optimum performance and extend the cleaning interval.
“The ionising bar is a key component in any static control system,” says international product manager David Rogers,. “However, it is the nature of such bars that they become contaminated during use and have to be cleaned regularly in order to remain efficient.
“The 977CM system has the ability to continuously monitor output from the ionising bars and will automatically adjust the input voltage to compensate for the adverse effects of contamination. When this has increased to a preset level (typically +25 per cent), further deterioration in bar performance will alert the operator, via local audible and visible warnings and remote alarm signals, to the need to clean the bars.”
The new system also features a fully automated closed-loop feedback system. A sensor bar detects residual voltages on web paths and rewinds and communicates with the 977CM unit to instruct it to tune its output to ensure the best possible charge neutralisation for the current operating conditions.
The 977CM is said to be straightforward to install and connect to existing Meech Pulsed DC static elimination systems.
