Software for Sprinkler Calculation

  2. 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. And also in other European countries and beyond our programs are used by numerous customers. The software is except in German also completely in English and largely available in French.

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.” Despite 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

As a rule, 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


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.

There is also a connection to VenturisIT’s TriCAD MicroStation CAD system so that hydraulic calculation can be performed directly on a pipe network entered in TriCAD.


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.

Inputs are graphical, either in plan view or in isometric view (you can switch between both views at any time). You can also draw a sprinkler network in existing AutoCAD floor plans (for example, an architect’s plan).

At the push of a button, SpriCAD® prepares documents for prefabrication; Cutting lists and a compilation of all required pipes are also generated automatically.

Another advantage of the pipe network input via AutoCAD or BricsCAD is the possible further use of the geometry for, for example, building plans, architect floor plans, etc.


SpriCAD® for   AutoCAD/BricsCAD   allows:

  • carrying out hydraulic calculations of sprinkler systems
  • the preparation of isometric views for testing by the VdS
  • Assistance in the preparation of construction site plans
  • the creation of parts lists
  • automatic positioning of the sprinklers
  • the preparation of documents for prefabrication


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 allows:

  • a selection of elements that are necessary for the calculation or omission of elements that are not necessary (for example, heating or water pipes).
  • assign an active area to each sprinkler.
  • carrying out hydraulic calculations of sprinkler systems
  • Coloured representation of the calculation results: flow rate of the water, pressure loss and flow velocity.
