We use Industrial PLC technology for automation and CVD system. By employing an automatic MKS Throttle Valveand a MKS pressure controller which works in conjunction with a Pressure Baratron (pressure transmitter), and a Vacuum pump maintains the required low pressure or vacuum required for the CVD growth process of the material (Graphene in this particular case). With the integration of MKS Throttle Valve and a MKS pressure controller one could ensure stable pressure inside the reactor chamber and repeatability. A PALL filter employed with an activated charcoal chemical Scrubber removes all the harmful chemicals which is the biproduct of growth process.
