Equivalent Pipe Length Adjustments

The piping layout captures length and number of bends. The app then calculates the equivalent pipe length and adjusts capacity. It won't accept an equivalent pipe length outside of the design range in order to prevent mistakes.

Altitude Adjustments

The app adjusts capacity based on altitude. Save your local altitude in settings. You can adjust for the working altitude of any job outside your local area.

Maximum Pipe Length Check

The app knows the maximum pipe length for all units; it checks so you don't exceed this on your layout. The app won't accept an equivalent pipe length (based on the number of bends) outside of the design range to prevent mistakes.

Ductless Layout

Layout view captures pipe length, bends, branch boxes, distribution pipe (joint), and IDU height above or below ODU.

Avoids Common Mistakes*

It won't let you enter an out-of-range value.
