FRÄNKISCHE data sets and CAD libraries

To be used in the liNear Software Solutions, the FRÄNKISCHE alpex 50 PROFI press system was first detected. It is available as a free data set for both the potable water pipe network calculation (liNear Analyse Potable Water) and the heating pipe network calculation (liNear Analyse Heating).

The system is designed using the new alpex F50 PROFI fittings, which are available in dimensions of 16-32 mm. With a cross section surface 30 % larger than that of previous versions, these fittings are flow-optimized. The fitting thus has the largest inner diameter in the segment of radial compression fittings for multi-layer composite pipes in Germany. With optimized flow rates, they enable minimal and economical dimensioning for potable water and heating installations.

Ideal wall thicknesses of the pipes also guarantee a large inner diameter for all alpex multi-layer composite pipes. These go perfectly with the optimized fittings and qualify alpex F50 PROFI as a flow-optimized and future-proof all-in-one system - flexible, compliant with regulations and reliable in use.

The alpex F50 PROFI system data can be selected as usual in the liNear software solutions by displaying the pipe networks either in the schematic view, in the floor plan or in the isometry and their complete graphical recording as material basis.

The respective calculation program checks the drawing for possible implausibilities, e.g. in the context of standard conformity, and displays them already during the detection. Various visualization options make the calculation results clearly.

The calculation programs determine all components and materials of the considered system in a single step. When using manufacturer-specific data sets of  FRÄNKISCHE, the dimensioned products get the right article number to ensure that they have the right product descriptions when transferring them to quotation programs.

All known formats are available: Windows printout via integrated print masks, export of bill of quantities in ASCII format to word processing programs, transfer to Microsoft Excel, ASD interface export to the liNear tender document or output as a GAEB file for data exchange with programs for creating tender documents.

The data set is suitable for the following liNear software solutions:
