aquaTurm in Radolfzell on Lake Constance First zero-energy high-rise with CITEL surge protection
The review
It all started when Norman Räffle came to the second
Christmas Day 1998, the old water tower in Radolfzell on Lake Constance came to our attention. Still at the same
In the evening father and son looked at the condition of the building.
The concept for the aquaTurm changed from a
pure view café over a restaurant, an office and
residential buildings up to the design hotel with a view over the
Lake Constance, one of the most beautiful areas of Germany.
During the planning period it was decided
the tower of the world's first zero-energy high-rise
to design.
In eight years of construction time, a lot of own work was done in
different trades like civil engineering, demolition, carcass
and facades the construction progress is rapidly advanced.
Electrical engineering
During the electrical work the company ELBAG from Stockach was in the boat or in the tower. The managing director, Frank
Gora, managed the project itself and supervised the construction
the distribution cabinets, which are the heart of the electrical
Form power distribution. They also contain all safety-relevant components for the first zero-energy high-rise building worldwide.
We at CITEL supplied the products for protection against lightning
and overvoltages.
The lightning and surge protection
As a central protection was developed by the company ELBAG in
Feeding one lightning current combined lightning current arrester (type 1+2+3)
DS134VGS-230 from the company CITEL. Additionally, coordinated "Type 2" DS44-230 surge protection devices were installed in the sub-distribution boards.
The DS130VG series with 12.5 kA discharge capacity per pole is
a space-saving and inexpensive solution for buildings of
Lightning protection classes III+IV and fulfils the minimum requirements for type 1 lightning arresters according to VDE 0100-534
The DS130VGS combines the integrated CITEL VG technology
as combined arrester type 1+2+3 all three protection classes in
a device and thus offers a very good protection
against overvoltages for the downstream system. The
DS130VG also complies with the VDN guideline and can therefore
can be inserted in the pre-counter area into the feed-in.
The DS130VG series is therefore ideally suited for installation in
for private and commercial buildings.
The surge protection devices of the DS40x series are
as a type 2 arrester due to its surge current discharge capacity
and are mainly used in sub-distributions of electrical systems.
The protection circuit of the DS40x series consists of a
Combination of high power varistors with a thermal break device, fault indication and optional
with remote signalling. The DS40x series is designed for electrical
Systems with a wide range of operating voltages
and network forms available and for top hat rail mounting
suitable. The pluggable protection module allows quick and uncomplicated replacement in the event of a fault.
We attach great importance to comprehensive support for planning offices and installation companies. The technically experienced
Together with the processors, technical advisors seek the
technically optimal solution for the user, of course
from a commercial point of view.
