nVent HOFFMAN has a new Cooling Selection Tool available at: coolingselection.nvent.com.

This tool will be turned off and will redirect to the new tool on September 1st, 2020. Until then you may continue to use this tool, but we will no longer be providing updates or support.

Welcome to the Hoffman cooling selection tool. Enter the requirements of your application. The software will suggest standard cooling solutions such as air conditioners, heat exchangers, and air movers. If you need a custom solution such as custom paint option, increased air flow, or unique dimensions, please contact your sales representative.

    Estimate Heat Load using Temperature

    Internal heat load can be deteremined by measuring the difference in temperatrues between the inside and outside of the sealed enclosure with no fans running and all components operating at full power. It is imperative that no ambient air is allowed to pass through the inside of the enclosure.

    Temperature in Degrees

    Estimate Heat Load Using Voltage and Amps

    Watts of heat load can be determined using the voltage, amps and efficiency of main components in the enclosure. If efficiency is unknown, enter 0%.

      Voltage Amps Efficiency Quantity
    Component A %
    Component B %
    Component C %
    Component D %
    Component E %

    Estimate Heat Load using Industrial Automation Components

    Watts of heat load can be determined from popular industrial automation components. enter below key components inside the cnclosure. Model assumes 97% efficiency for VFD and 95% efficiency for servo drive and transformer.
