* Calculate Watt Density - You can input the corona power (W, kW), the corona width (in, ft, cm, m) and the web speed (ft/min, m/min). Your watt density result can be in watts/sqft/min or watts/sqm/min. You can also forward or reverse calculate any of the input values. Just provide any three values and the fourth one will be calculated.
* General Info - General information on different types of corona treaters.
* Film Diagram - A graphic to label the basic parts of a corona treater.
