Efficient HVAC design relies heavily on accurately calculating pressure losses in ductwork systems. The is the industry-standard software tool used by mechanical engineers, HVAC designers, and estimators to determine the loss coefficients of various duct fittings.
Reduce energy consumption by designing systems with minimal aerodynamic resistance.
