Program Improvements

  • Default  Drive Loss - All belt drive fan models now default to “Low” drive loss or 3% allows for proper motor sizing.
  • Revit® Drawings  - We have doubled the amount of dynamic Revit® Content since our last release.  Most models will generate specific dynamic Revit drawings to match your product selection in CAPS. This is not a "generic" drawing but a true representation of the product and options you select for your specific application.
