Software for Sprinkler Calculation

IDAT GmbH is the leading and long-standing supplier of software for the calculation of sprinkler systems in German-speaking countries – because we have been involved in software development for over 35 years. Our programs are also used by numerous customers in other European countries and beyond. The software is available in German, English and mostly in French.

With our sprinkler software you perform the hydraulic calculation for the following types of extinguishing systems:
– Sprinkler systems (incl. dry systems)
– Water spray extinguishing systems
– Foam extinguishing systems
– Water mist systems

Certification of sprinkler software

The VdS has issued the following confirmation: “The program meets the accuracy requirements of the calculation set out in the draft directive and can be used for the calculation of sprinkler systems according to VdS CEA 4001 as well as water spray extinguishing systems according to VdS 2109.” With high computational accuracy, the results are determined very quickly due to an optimized calculation method.

The calculation is also FM-Global and NFPA compliant.

Calculation options

By default, the pressure loss is calculated according to the Hazen-Williams formula. As an additional option we offer the calculation according to the Darcy-Weisbach formula (e.g. for foam or fine spray extinguishing systems).

Apart from sprinkler systems, spray water extinguishing systems can also be easily calculated.

General information

With WinSprink, a proven and successful program for the hydraulic calculation of sprinkler systems has been designed. The basis for the WinSprink program is its calculation kernel, which can be used to hydraulically calculate not only tree-like but also all types of meshed piping systems.
For each pipe section, the program outputs the following information after the calculation:

  • Number of the pipeline
  • start and end node number
  • Pressure at the beginning of the line section
  • For Sprinklers, the  K-Factor
  • the flow rate at the sprinkler
  • the amount of water in the pipe
  • Pipe diameter and length
  • fixtures (number of bends, angles, tees …)
  • the hydraulic length
  • Pressure loss due to friction
  • Height difference
  • the total pressure loss
  • the pressure at the end of the pipe
  • the flow rate in the pipe section

System requirements

Operating System: Windows 10 or higher, 64 bit

Sprinkler calculation with CAD support

In addition to the WinSprink program, we have developed the SpriCAD® program for various CAD systems. With CAD support sprinkler systems can be entered and calculated here. For this we offer attachments for AutoCAD, BricsCAD and Revit.

We also offer an interface to Microstation CAD system TriCAD MS by Venturis IT GmbH and CARF by LuArtX IT GmbH, both allowing the hydraulic calculation to be performed directly on a pipe network entered in TriCAD/CARF.

Sprinkler calculation with AutoCAD and BricsCAD

As an alternative to WinSprink, SpriCAD® calculates the sprinkler system in the CAD system AutoCAD or BricsCAD. The operation of SpriCAD® is straightforward and follows the usual AutoCAD commands.

Graphical inputs are made with the SpriCAD® tools in isometric 3D display with pipe and node numbers. You can also draw a sprinkler network into existing AutoCAD floor plans (e.g. architect’s plan).

Another advantage of the pipe network input with AutoCAD or BricsCAD is the further use of the geometry for e.g. building plans, architects’ floor plans, etc.

SpriCAD® for  AutoCAD/BricsCAD :
  • 3D-Single line method with SpriCAD®-Tools
  • Isometric display incl. pipe and node numbers
  • Visual result display for flow rate, flow velocity and pressure loss
  • Automatic distribution of sprinklers in a room
  • Creation of part list


Sprinkler calculation with Revit

The network is entered through Revit commands or other external programs supporting Revit. Configuration settings can be used to adapt to the sprinkler network entered.
Another benefit of using Revit pipe mesh is the potential reuse of the geometry e.g. for building plans, architectonic plans, etc., or linking or integration into BIM projects.
Revit itself again offers the possibility, e.g. also to create material lists.

SpriCAD® for Revit:
  • BIM-compliant 3D planning
  • Direct calculation from the model
  • Additional equivalent length in families
  • Calculation with individual diameter when using mixed pipe materials
  • Collision free planning
