KMaximised flexibility and mini-
mised design effort for custo-
mers, because all radial fan
casings have identical dimen-
sions no matter what kind of
impeller geometry
Nicotra Gebhardt stands for:
KTop product quality and shor-
ter delivery times thanks to
state-of-the-art production
technology
KEnergy efficiency through com-
prehensive system know-how

A strong provider for many optimal solutions:
The Nicotra-Gebhardt portfolio
When it comes to radial fans, we are the first people you should talk to. From belt-driven radial fans to
plugfans, its all there in our product portfolio. We offer the largest, most comprehensive range of products
in this area and of course the matching services.
When everything fits:
100% compatible product series
Well designed, easy to install, economical
The compact base frame from Nicotra-Gebhardt
A system that saves space, time, and money in an
air handling unit or any other application: our com-pact base frame offers decisive advantages:
KThe frame lengths have been optimised and
adjusted for the casing position and motor
installation height to achieve the smallest possi-
ble overall height and length
KExact, optimised coordination of all components,
all the way through to installation, adjustment
and testing
KSuitable for all fans of the series ADH-E0, RDH-E0 and RZR-11 up to size 0500Greater system efficiency

To us, perfection in our product portfolio means that
all product series in the area of encased radial fans
are attuned to one another and are 100% compati-
ble in their dimensions.
How did we do it?
By using an identical design for the connection di-
mensions of every fan size in our newly developed
series ADH-E and RDH-E and carefully coordinating
our options and accessories.
In this way, we have standardised and harmonised
our product portfolio in all relevant areas.

proSELECTA II
proSELECTA IIis a technical selection program that allows you to configure your own individually de-
signed fan. It provides you with the opportunity to choose from the entire range of fan types and their
associated options.
Simple and reliable selectionThe result from proSELECTA IIis the provision of all the
technical data for your fan, including sound level data, dimen-
sion specifications and accessories. Apart from that, as a re-
gistered user, your purchase prices are provided. Additionally
fully dimensioned drawings in DXF format are available, which
can be downloaded and transferred straight into your CAD
system.
So that you can be sureModels and options that are technically not permissible, are automatically excluded in proSELECTA II. So
there is no chance that you will configure a wrong device option.
What else is important to you
During the fan selection process, you can choose any of the standardised ATEX options.
Free registration and many advantages
You can register as a proSELECTA II user with us, which enables us to offer you faster order processing.
What this means for you is:
KThe complete configuration of your fan with its
associated system accessories and belt drive
layout.
KThe possibility to produce fans that operate via a
frequency inverter.
KThe option of saving your own fan configuration
on our server.
KThe opportunity to modify your saved configu-
ration, even over the phone to your Nicotra-
Gebhardt representative.

Highest system performance and best energy efficiency:
Therotavent RZR series
It is not difficult to make a centrifugal fan for an air conditioning unit a few euros
cheaper.
But to construct it so that it saves valuable energy during operation is a real technolo-
gical challenge.
In this respect, therotaventfrom Nicotra Gebhardt continues to provide the technolo-
gy with the highest level of system performance and with that, the best solution where
energy efficiency counts.
rotavent the efficient fan technology with centrifugal impeller and airfoil blades.
Top quality for performance and a long service life!
The advantages:
Wide range of application even for high pressures
Easy adaption to changed operating conditions thanks to the belt drive
Easy and reliable layout, performance data complying with tolerance class 1
High degree of performance density at the best efficiency
Low level of noise thanks to the blade profile, a patented blade positioning and the
V-cut off
Easy selection via the proSELECTA II electronic catalogue
We do it very precisely!
Or
Why you should not compare apples with pears!
Nicotra-Gebhardt manufactures its centrifugal fansrotaventwith tolerance class1 in
compliance with DIN 24166.
This gives you the necessary degree of security that you need when designing and
planning ventilation installations. The tolerance class is also an important criterion for
the objective comparison of fans.
If you compare the price/performance ratio of two fans, you should also always take
the tolerance class of each into account, only then do you avoid comparing "apples
with pears"!
