About us

In the mid-1990s, Dipl.-Ing. Rolf H. Keidel developed a soft- ware for planning and calculation of Siphonic Roof Drainage, which was sold worldwide under the name DrainStar® Siphonic Calculator. Mainly tailor-made software packages were developed for manufacturers and design and build companies.

The manufacturers also sold the Keidel software under their own name. These individually developed software packages required a long development phase and constant adaptations and were therefore only reserved for large companies due to the relatively high costs. It is estimated that around 100 million square meters of roof surface have been successfully calculated with the DrainStar® Siphonic Calculator.

 

Siphonic Roof Drainage has now become the standard roof drainage system because of its ecological and economic advantages. Many small and medium-sized companies are entering this lucrative market.

 

In response to this rapid development, Dipl.-Ing. Rolf H. Keidel developed a compact software series from the proven DrainStar® Siphonic Calculator at a low price and brought it into new company KEIDEL DrainStar GmbH.

 

The focus of the compact software series is fast and safe dimensioning of the pipework with suitable pipe systems. Adjustments can be organised by our customers themselves using password-protected tools. As with its big brother DrainStar® Siphonic Calculator, various parts lists, hydraulic calculation, isometric drawing, and a list of pipework properties are available.
