  • A balance section, which can calculate adjustments based on fluid type and has a report generator to aid balancing contractors, with preset and gauge data for circuit setter, large circuit setter and triple-duty valves.
  • Help in calculating system head loss.
  • A library of fittings, reducers and valves.
  • An NPSHa calculator with open- and closed-system support.
  • More fluid property information.
  • Lock icons to indicate what variable is to be solved.
  • Expanded pipe size calculations through 48 inches (dia.).
  • ASHRAE 90.1 pipe-sizing standards, in addition to estimated pump energy cost based on pipe sizes.
  • Support for PVC and HVAC pipe.
