Pan Coater Control Systems

BRAND NEW FULLY AUTOMATED CONTROL SYSTEM FOR 48" and 60" PAN COATERS
GENERAL DESIGN:
The ASC Coater Control System is designed for aqueous film coating. The system is composed of two basic panels: a power panel, and an operator panel, or HMI (Human Machine Interface). The power panel is typically remotely mounted in an accessible equipment room, while the HMI is typically mounted near, or on the coating pans itself. The system can control all functions associated with pan coating including airflow, temperature, differential pressures, dust collectors, air handling units, and spraying systems.
The companion spraying system consists of a separate stand-alone unit That uses a single Ethernet cable for robust interoperability. This provides for start, stop, clearing, and solution recirculation to all be controlled from the coating pan userer operator panel. The airflows through the spray guns are measured by atomization airflow displays (Flow Balancer®). And those values are passed to the user operator panel for streamlined gun setup.
EASY ACCESS AND MAINTENANCE:
Both the power panel and the HMI panel are equipped with hinged doors for easy maintenance access. The system includes an upgrade to the coating pan drive system which includes a new Inverter duty gear motor and a state of the art belt drive and pulley configuration. This new drive system greatly improves reliability, reduces noise and reduces maintenance intervals and costs.
USER FRIENDLY:
Our control and HMI user interface are designed from the ground up to be as flexible and more user friendly than any system in the industry. The controls include optional features for just about any process variable that needs to be controlled for pan coating. Manufacturers can choose the type of variables the system needs to control, and ASC will activate those options required to meet the end user needs. All this in a single set of controls that can be delivered now, and reconfigured later as needs might progress. Provisions have been made in the hardware and software design to accommodate expansion of features. These options can be activated as a Professional Service, rather than having to have a new set of controls built and delivered. Most features and functions can be optionally monitored via a network connection for convenience.
CONTROL SYSTEM DESIGN:
The design is based on fiercely reliable Rockwell / Allen Bradley components. The color touchscreen control system provides automated process control, recipe development, maintenance mode, and “log-in” security screens. A POS 2” printer is provided and is easily accessible by system operators. The printer allows process parameters to recorded at interval for post-process data analysis. The printer also records process elapsed times as well as recording alarm and fault If 21 CFR Part 11 compliance is required, the control system can be upgraded to the ASC Coater Control E model, Automation Sciences Corporation’s most robust and complete control system. The Coater Control E automated control system offers automated process control and electronic data management that is consistent with 21 CFR Part 11.
