Diesel driven units - whereelectric power supply doesn‘t exist…
In the early 90's Bock became a solution provider for Diesel
driven train sets operating in the different areas and countries
where electric power supply was not available.
Open type compressors of the FK range found to be the best
solution empowered by well known quality and reliability from
the field of bus HVAC applications. Rail operating conditions,
normally stated to be much more demanding compared to the
automotive ones, didn‘t bring any obstacles for Bock technology
and the FK range started to become the favourite product for
railway HVAC applications.
Railway international standards of reliability and durability finally
lost the battle against Bock‘s common sense for the detail and
quality, which, by the way, always differentiates first class
products from the others.
Since that time Bock has been sucessfully cooperating with
many HVAC manufacturers supplying DMU markets such as
Sütrak Carrier, Behr, Konvekta, Rexxon, Faiveley or Webasto.
Bock is proud to deliver real value to rail OEMs. Namely to
Bomdardier, Alstom, Siemens and Stadler. These customers
operate their DMUs under the brand names Bombardier Talent,
Alstom Coradia Lint, Siemens Desiro or Stadler Regio-Shuttle. All
of them having “Inside.Bock“.
All the trains are in full operation nowadays and in case of new
vehicle demand on the market, Bock is providing proved
solutions like they did in the past when all mentioned projects
started.
Bock is always at your side.

Bock is continuously performing customizations and working
on new product developments to respond to latest markets
trends. Today, the company can offer rail customers great
products tailored specially for low weight and high
performance requirements.
In the last years, we developed special aluminium semi-
hermetic compressors where weight reduction, compared to
the standard product range, is reaching tremendous values
of 35%. To give you a particular example: Imagine a typical
metro vehicle of 4 saloon cars, each having one HVAC unit
with split system. This amounts to either 1200 kg using the
conventional design of compressors, or 464 kg when using
new state of the art Bock technology combining aluminium
design and the newest 2-pole motors. Possible reduction of
the weight load of compressors is 61% for one vehicle,
which brings a remarkable result energy wise, especially
when you consider the whole fleet of vehicles. Plus there will
be certainly also other positive aspects related to the design
needs of HVAC units and vehicle roofs.
Since many years Bock compressors are working in the Delhi
Metro in India. Furthermore, Bock is proud supplier of the
Hong Kong Metro and various other metros.

NEWSBock Compressors in Russia's fastest train
Reliable even in the Siberian WinterIn April 2006 and May 2006, Siemens and Russian Railways
RZD signed contracts for the development, construction and
service of high-speed trains for 30 years. The project
encompasses the delivery of eight high-speed trains. Those
trains are models whose components and systems have to
be adapted to the special climatic requirements as well as
the standards of the Russian Federation.
The ten-car trains will operate on all high-speed routes in the
Russian Federation starting with Moscow – St. Petersburg.
Based on state-of-the-art high-speed technology the trains
are characterized by an attractive design in the Russian
national colours.
Because of the high demands on the air-conditioning that is
exposed to temperatures up to -50°C, the application of
high-quality components was without question.
For the compressors, the heart of modern air-conditioning
and refrigeration systems, semi-hermetic compressors by
Bock were chosen. “We deliver high-end compressors that
are produced at our German headquarters. For a maximum
safety, all compressors are equipped with reliable oil pump
lubrication.
Even for the most extreme operating conditions of -50°C and
up to +54°C ambient temperature, a safe operation is
guaranteed”, says Marcus Reuß, Bock Key Account Manager
Railway Applications. The compressors have an established
design and more than 10.000 compressors of this size are
already used worldwide.
“As a medium-sized enterprise we are able to respond to our
customers wishes, especially when it comes to smaller order
quantities. A fact that has proven to be an advantage, such as
in the case of the compressors for the SIEMENS VELARO®
RUS high-speed train” says Marcus Reuß.

Since the HG34P followed in the footsteps of
the HG3 in 2003, it developed into a top seller
of the Bock product range and is now used in
refrigerating and air-conditioning systems
around the world.
Apart from its application in trains, the
HG34P also ensures comfortable air-
conditioning in trolley- and hybrid buses.

Compressor solutions for mobile applications
Smaller, lighter, stronger -Bock Aluminium CompressorsModern railway air-conditioning systems have high
demands on the different components of a system. Based on
those customer demands, Bock has developed special
aluminium compressors for mobile use.
The demands in the railway area that led to this development
can be roughly divided into four parts:
- Compact dimensions
- Lightweight Construction
- Sustainability & environmental protection
- Maximum efficiency
Bock responded to all those demands and developed its
semi-hermetic aluminium compressors HG22P and HG34P.
Compressors that were developed together with system
manufacturers and are already used in many trains.
For example in the new railway generation of the Scottish
Railway – First ScotRail. First ScotRail is responsible for
nearly all the rail traffic in Scotland. In 2010 First ScotRail
expanded its fleet by 38 environmental friendly trains of the
type “Class 380” with about 9.000 air-conditioned seats.
The trains of the model Desiro UK are delivered by the
Siemens railway technology branch. The trains are
manufactured in Krefeld-Uerdingen, Germany. The contract
with Siemens that was already signed in July 2008 has a
volume of more than 300 mio. Euro and also covers
maintenance and spare-part service.
The fact that Siemens chose the semi-hermetic Aluminium
compressor Bock HGX34P/380-4SA is a proof to Bock that it
was the right decision to focus consequently on customer
demands in this area.
In general one can say that the growing specific
requirements of the different refrigeration and air-
conditioning applications present new challenges for the
compressor. At Bock this challenge is seen as a chance to
further establish as a specialist for radial piston compressors
in various industries.
The Compressors - Bock HG34P in aluminium design
The compressor HG34P as well as its
smaller brother HG22P in aluminium
design was developed especially for the
demands in mobile areas of application.
Because of its aluminium-lightweight
construction, it has about 40% less weight
than comparable compressors.
Since its presentation at the Innotrans
2008 in Berlin, those compressors are met
with great interest and are already used in
various applications.

NEWSBock compressors in the trams of Germany‘s capital
Berlin's trams equipped with Bock CompressorsAs part of the modernisation of their tram fleet, Berlin's
transport services (BVG) placed an order for the production of
100 low-floor vehicles of the model FLEXITY Berlin with
Bombardier. Initially, four pre-series vehicles in different
variations are delivered. After a test and pilot phase, 206
additional trams can be delivered.
For the compressors, the heart of modern air-conditioning
and refrigeration systems, the manufacturer Liebherr-
Transportation Systems chose once again semi-hermetic
compressors by Bock Kältemaschinen GmbH.
“The project places high demands on Bock as the
manufacturer. They were searching for a compressor with
compact dimensions and minimal weight” says Marcus
Reuß, Bock Key Account Manager Railway Applications.
To meet those demands, Bock used the long experiences in
the manufacturing of open aluminium lightweight
compressors.
With those compressors Bock sets the benchmark in bus air-
conditioning worldwide. With the help of this know-how the
company developed semi-hermetic compressors in
aluminium design especially for mobile applications such as
those modern rail vehicles.
“With this lightweight aluminium type we could fulfil the high
demands of the train manufacturer for the Berlin railway and
we can see great potential for this product in various other
rail-projects as well” concludes Marcus Reuß.

Nowadays a topic that is gaining in importance all over the
world is the use of environmentally friendly refrigerants.
Many HVAC companies have R&D projects running for the
application of CO as refrigerant in the mobile area. 2
bus or rail applications and are
ready to meet these latest worldwide challenges.
However, matter of fact is that the use of CO in passenger 2
transport still remains a question mark. The overall impact in
this field would be significant and would mean extensive
changes in many related areas as well.
The demand for environmentally friendly refrigerants is
growing and other refrigerants besides CO are considered 2
as well. The use of those alternative refrigerants would be a
smaller step compared to the use of CO , but it seems to be a 2
probable next step coming in the near future.
Nevertheless Bock can provide components to build
prototypes of HVACs and allow OEMs in the HVAC area to
perform research and development activities in the field of
CO as well as in any other refrigerant fields.2

New product launchesfor HVAC Rail.
Bock offers its compressor HG34P in a version for 50 Hz with
2-pole drive motor, double rotation speed, and corresponding
higher capacity already for some time. At this year's
Innotrans, Bock now presents this compressor model for 50
Hz as well as 60 Hz.
This additional increase of the maximum possible
compressor capacity is achieved by the application of a
special valve plate system. The so called Bock K-valve plate
that was developed by Bock especially for mobile air-
conditioning applications is already in use in thousands of
applications and setting the worldwide benchmark for
quality and reliability.

developed two special versions for mobile applications, such
as railway air-conditioning.
With the two models HG22P and HG34P in all-aluminium
lightweight construction, Bock offers the perfect solution for
all applications where the weight of the compressor is
important. No matter if it's about railway-, bus- or mobile air-
conditioning – those 40% lighter compressors (compared to
standard compressors) offer new possibilities to system
manufacturers.
Additionally, those compressors are available with a terminal
box in a reduced height and therefore even more compact
than the standard version. For especially capacity-intensive
applications, such as mobile air-conditioning, Bock offers the
Pluscom Model HG34P in 2-pole version.

Bock already offers for some years a compressor-selection
software that helps you to find the right compressor for your
system by entering the corresponding technical
requirements.
Since the selection software included the whole Bock
compressor range for stationary as well as mobile
applications until now, the software did not take railway
specific characteristics into consideration. Starting in
September 2010, Bock offers a special railway version of the
VAP compressor selection software that will make it much
easier, to find the right compressor.
Another highlight of the new VAP for mobile applications
compared to other selection programs is the fact that it is an
online software that works without an installation on the
computer. All you need is an internet connection.
