The HAUTAU drive calculator ensures reliable planning when dimensioning drive solutions. This project planning tool can be used on any Internet browser, irrespective of the platform, and offers the perfect individual drive solution once specific information has been entered for the window concerned. A bill-of-quantities generator helps to produce professional bills of quantities for use as an integral part of RFP documents. Visitors can try out the project and design tools at a software workstation on the HAUTAU exhibition stand, where the new 2107 catalogue is also available for anyone who wishes to take a look at the whole range of HAUTAU building automation products. The print version is, of course, also available in addition to the app for Android and iOS.
