Sizing in three steps

Welcome to a quick instructional guide on how to use the Noren Products Heat Exchanger Sizing Program. This guide is designed to be short and sweet - of course feel free to post questions you may have and the Noren Products Webmaster will address then as soon as possible.

What you'll need:

  • Cabinet dimensions
  • Internal temperature, or wattage of internal components
  • Number of sides the cabinet has exposed 

Ready, set, go: norenproducts.com/sizing

  • Step One: Choose your cooler category
    • Air to air (heat measured by temperature)
    • Air to air (heat measured by watts)
    • Air to water (heat measured by temperature)
    • Air to water (heat measured by watts)
  • Step Two: Choose how many heat exchangers will be required
    • Enter 1 if your enclosure is not in an extreme heat location
    • Enter 2 if your enclosure is in an extreme heat location such as a desert or tropical environment
  • Step three: Specify Cabinet Parameters:
    • Enter the Height, Width, Depth of your enclosure
    • Enter internal temperature in farenheit as well as your external temperature (also indicate water temperature when choosing an air to water unit in Step One
    • Indicate number of exposed surfaces
  • Run Program: click the "Run Program" button at the end of the form.
  • Results are presented in the table on the right hand side of the screen
  • Use this table to choose a heat exchanger that best meets your cooling needs
    • All unit model numbers are linked to the corrasponding product page or pdf document wiht more information about that particular unit
