Control Panel Heat Calculator
This calculator pertains to NEMA or IP rated control panels. These control panels may contain electrical terminations, start/stop controls, and at times more sophisticated control methods such as an HMI. Most industrial applications require sealed unvented control panels to protect the components housed inside.
To use this control panel heat calculator one must first quantify the amount of heat generated by components inside. With total heat calculated, the calculator determines the expected temperature rise based on the control panel size and type. The graph shows the expected temperature rise. Mitigation of the temperature rise occurs by venting or air conditioning, depending on the amount of heat that must be displaced and site-specific requirements.
