UNI-DUCT® Supply Program

UNI-DUCT software employs the static regain design method enhanced by the total pressure method to design efficient supply systems. It creates static regain designs, analyzes pressure requirements, and determines a system’s design leg or critical path (path of maximum static pressure requirement). Since nondesign legs and branches have excess static pressure, they need to be balanced. Unless a system is balanced, air will not be distributed properly. Some outlets will receive too much air, while others will not receive enough.

UNI-DUCT uses a complex iterative procedure to reduce duct and fitting sizes in the non-design legs so that the available total pressure balances the system. The program evaluates each fitting to determine whether it can be replaced with a less expensive fitting that will perform the same function. These new fittings will use additional available total pressure, further balancing the system. By reducing duct and fitting sizes to balance a system, UNI-DUCT provides duct system designs with low material costs.

UNI-DUCT also designs balanced duct systems for a preselected system target pressure. Once all data has been entered into the program, a duct system design is revised simply by changing the initial parameters. This makes it easy to redesign a duct system for the lowest operating costs over the system’s lifetime.
