A smarter way to handle sprinkler design and hydraulic calculations
The vCalc and vDesign package simplifies fire protection system design. It allows engineers, designers, and students to create complete systems, perform accurate hydraulic calculations, and visualize layouts in 3D. The suite is free, fully customizable, and provides easy access to the full Viking Revit library.
To access the vCalc tool, a licensing form will be sent once vDesign has been downloaded.
