VariTrane Duct Designer streamlines duct design and improves
calculation precision, letting you optimize your designs while
obtaining a minimum pressure system. VariTrane Duct Designer enables
you to organize the layout structure of your duct system and provides
detailed engineering information on a section-by-section basis making
revisions and updates easier.
The software is based on engineering data and procedures
outlined in the ASHRAE Fundamentals Handbook. It includes
tested data from ASHRAE Fitting database and from United McGill to
provide the most accurate modeling possible.
