An advanced sizing tool that helps users configure filter fans, cooling units, air and water heat exchangers, and heaters for electrical enclosures is downloadable directly from Lancaster, N.Y.-based Pfannenberg USA’s web site,

To achieve proper sizing for effective thermal management, the “Sizing Software” tool works for both indoor and outdoor applications. It can calculate the heat dissipation in a cabinet component-by-component as it guides users through the sizing process. The tool can be customized to specific applications by entering component and enclosure styles into a database that performs the calculations.

Available free from the web site, the software is compatible with all current Windows operating systems and offers a simple interface.
