Shell And Tube Heat Exchanger Revit Family Work Fixed (2025)

For a professional Revit family of a shell and tube heat exchanger, the documentation and parameters should focus on mechanical accuracy and BIM integration. Project Description / Overview

for the cylindrical body. Ensure you lock the ends of the extrusion to your length reference planes so the shell stretches when you change the parameter. Headers and Ends shell and tube heat exchanger revit family work

Step 4: The Saddles (Supports)

• Create an extrusion on the bottom of the shell.
• Parameter: Saddle_Height (From floor to shell bottom).
• Parameter: Saddle_Width.
• Use a formula to center the saddles: D1_Offset = Shell_Length * 0.2 (20% from each end).

| Parameter Name | Formula | Purpose | | :--- | :--- | :--- | | Total_Length | Shell_Length + (Channel_Length * 2) | Overall equipment length. | | Center_of_Gravity_X | (Shell_Length / 2) + Channel_Length | Rigging coordination. | | Tube_Pull_Area | if(Tube_Pull_Required, Shell_Length + 500mm, 0 mm) | Dynamic clearance. | | Nozzle_Projection | Flange_Thickness + Insulation_Thickness | Accurate outer envelope. | For a professional Revit family of a shell

• Shell body (host)
• Tube bundle (nested) — can be simplified as a cylinder with patterning omitted for performance
• Nozzles/flanges (nested) — place Revit Mechanical Connectors on these nested families if appropriate
• Supports (saddles/legs) as optional nested families switched by visibility parameter

Clearance Zones: Integrated 3D "Maintenance Clearance" nested family to ensure adequate space for tube bundle removal during spatial coordination. Technical Parameters Included Create an extrusion on the bottom of the shell

The Challenge of Shell and Tube Heat Exchangers in Revit

Shell and Tube heat exchangers present a unique challenge in BIM environments. Unlike compact plate heat exchangers, shell and tube units are linear, heavy, and often require specific maintenance clearances. Creating a Revit family for this equipment requires balancing mechanical detail with file performance, ensuring the model serves both coordination and facilities management needs.
