"For 4 years we have been using the DrainStar Siphonic Calculator for various well-known German manufacturers of vacuum drainage systems as well as specialist consultants and architects with great success. Since then a number of installations have been functioning satisfactorily without any problems whatsoever. With transposition of the standards and rules applicable in Europe, the DrainStar Siphonic Calculator allows drainage system for flat roofs to be calculated quickly and reliably for many different construction methods. In a nutshell, the DrainStar Siphonic Calculator is a reliable tool that is key to boosting functional and economic efficiency in flat roof drainage technology."
Engineer (Dipl. Ing. FH) Hans Georg Aufmhoff

"The experience we gained with this software is very positive. The clear graphic presentation allows an easy editing and handling of projects and enables the user to run pipe network calculations very quickly. Further program features such as automatic generation of material lists, simple hydraulic adjustments and the option to calculate changes within the pipe network are also highly appreciated by our employees. Another highlight ist the clear layout of the calculation results, making it a simple task to refine the data calculations."
Jürgen Frei, former managing director of Wavin GmbH Plastic Pipe Systems

"In order to extend our roofing expertise to roof drainage, we began to search for suitable software for roof drainage with pressure flow. Our choice was the German company Keidel.
Our requirements concerning localisation and technical adaption of the software were fulfilled completely by Keidel. We were most impressed by your specialist competence, professional customer care, punctuality and reliability. This experience is an excellent basis for good and long-term collaboration."
C.M. Lee, director/general manager of  Helmed Company Limited

"We were immediately impressed by the intuitive user-prompting system, which only produces a single result. After we had entered basic data such as the width and length of the roof, height and position of the drop point as well as the rainwater level, the program did the rest. The results included not only the bills of material but also an isometry which can be used in CAD applications. One could hardly design a more practical program. We should like to inform you that we are entirely satisfied with your program and wouldn't like to do without it. We hope this program will remain on the market for many years to come."
Engineer (Dipl.-Ing.) J. Elsner, engineering office for building services   

"We chose KEIDEL GmbH as partner and supplier for the software because of their knowledge and references in this segment. It has been a pleasure working with KEIDEL during the construction phase. They are always helpful and available for any questions."
