Expansion Tank CV-S

This Revit family expansion tank CV-S is a mechanical component designed for hydronic system pressure management in building models. The CV-S expansion tank is a compact, cylindrical pressure vessel featuring a horizontal orientation supported by two integrated vertical steel brackets. The design includes a top-mounted connection port and circular end caps, indicating a standard industrial build for thermal expansion control within closed-loop heating or cooling systems. The form is purely functional, prioritising clear geometric representation for BIM coordination. Its simple, robust construction allows for easy integration into mechanical room layouts, providing a clean visual reference for engineers and contractors during the design and documentation phases of complex building projects.

The download is a 246 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

Engineers can load this family directly into a Revit project to represent expansion tanks within mechanical plant rooms. The model includes standard connectors for piping, allowing for seamless integration into existing hydronic networks. Users should verify that the family parameters align with project-specific flow and pressure requirements. The simplified geometry ensures minimal impact on model file size, making it suitable for large-scale MEP coordination where performance and efficient data management are critical for project delivery.
