The program allows performing the calculation of surfaces of ducts and their components,
determining the quantity of flanges, and generating a duct specification.

The results of the program are especially in demand for:

  • Production halls (the results will be used as the terms of reference for the manufacture of ducts).
  • Estimate departments (the results will be used for cost-determination).
  • Installation teams (the results will be used as detailed specifications for systems installation).

Browser support: Chrome, Opera, Firefox, Edge, Safari, Internet Explorer 10+.

  • Get the most up-to-date version of the program.
  • Use the program at any PC at any time.
  • Obtain specifications of ducts, duct fittings and flanges.
  • Obtain duct surfaces and material thickness values.
  • Obtain a summary surface table across all systems and material thickness values.
  • Use a wide range of settings.
  • Add, copy, change, delete, or move elements in a specification.
  • Copy, move, or delete a system directly with all embedded elements.
  • Combine all the systems into a single summary system.
  • Save specifications and summary surface tables as PDF file.
  • Save and load calculation results in a project file.
  • Use suitable system of units: imperial or metric.
  • Use the math calculator for additional calculations.
