gies and marketed systems and components for indoor ventilation and
air conditioning. We are consistently expanding upon this position by
means of intensive research and development activities.
The individual is the focus at TROX: as a customer with visionary
ideas and technological goals: as a motivated and qualified company
employee, as a responsible decision-maker at the management level
and, last but not least, as a human being who would like to live andwork in well-ventilated spaces.
Since our corporation was founded, we have stood by this philosophy
and vouched for our good name. Indicative of our solution-minded
approach, it has created our distinctive customer base and thus become
the source of our companys success.

The individual remains the deciding factorin all
that TROX undertakes. The individual, by virtue of his
or her visions, wishes, needs, abilities, and knowlege,
defines the goals that TROX pursues carefully and
deliberately.
TROX is an owner-led companywith horizontal
hierarchies in which the individual has decision-
making powers. Consistency, reliability, and a mature
feeling of responsibility for customers, employees and
the environment have been the pillars of the TROX
GROUP company politics for decades.
It is the customers of TROXthat decide how the
company will act on their behalf. They set goals based
upon their well-being as well as their architecturaland technological visions, and TROX in turn assists
them in realising those goals. The customer-oriented
corporate leadership has made TROX what it is today:
a world-wide and effective partner for those
demanding ventilation and air conditioning solutions
for all types of buildings.
Each and every employee contributes to the success
of the company in that they earn the customers trust
with their motivation and competence, and then they
confirm that trust day after day. The targeted trainingand continued education of our employees, as well as
their lasting job satisfaction, are thus important
concerns of TROX management.
The individual is the deciding factor

A tradition of innovation
The history of the companybegan with an innovation:
the specialisation in components for ventilation
technology. In the air conditioning industry, which
was still quite young in 1951, this was a revolutionary
decision. Trailblazing inventions have since marked
the rise of the company to the leading position inmarketing and technology. Innovations themselves
are tradition with TROX. The company holds over 200
patents and registered designs in ventilation and air
conditioning technology.
The systematic research and development of the
individual product groups enjoys increasing expansion
based on project-related development contracts.
With its customer-specific solutions, TROX sets an
innovating standard and, with that in mind,continues to enter new and lucrative markets and
maintain sustainable business opportunities. As a
result, TROX, since the introduction of the first
ceiling induction diffusers in the 1980s, has been the
leading supplier of these multifaceted products in
Europe.

Did you knowthat air is our most important element of
life? A human being can live without food for
over a month and without water for about a
week, but without air a person can survive no
more than three to five minutes at the most.
And we need a lot of air to live! While we are
quite adequately supplied with two litres of
water per day, we breathe around 20,000 litres
of air each day. In a poorly ventilated room,
the air is quickly used up. The concentration of
carbon dioxide mounts rapidly. The results are
fatigue and decreased performance.

As an internationally active company, we have come into
contact with the most pronounced climatic and cultural
differences in various countries and regions across the world.
Whether in South Africa, the United States, Brazil, China, or
Northern Europe, TROX ensures a well-tempered atmosphere.
Each building is a world in and of itself. Airports, off ice
buildings, hospitals, laboratories, and concert halls each have
their own completely individual needs for climate control and
ventilation technology.
And last but not least, each technical application requires
specific know-how - whether it is a tunnel damper, a central air
handling unit, or a multifunctional chilled beam.

Combination diffusers
Combination diffusers
Modern office buildings, which may for example have low energy
requirements thanks to use of concrete core cooling, require small air
exchange rates on the one hand, whilst providing very little room for
installing the ventilation on the other. In such situations, installing
combination diffusers into walls as a mixed or displacement flow system
is a compact and cost-efficient complete solution.

Displacement flow diffusers
Displacement flow diffusers allow cooled fresh air to be discharged into
rooms at very low air velocity and close to the floor so that a pool of fresh
air forms over the floor. This prevents air turbulence and thus drafts. The
air rises when it reaches sources of heat such as people or computers,
transferring the heat and the used air to the ceiling. The fresh air quality
in the areas occupied by people thus remains at the same especially high
level while maintaining a pleasant set temperature. Displacement flow
diffusers can also be integrated into wall areas or as columns in a room to
save space. They are made of galvanised and powder-coated sheet steel
and available in a variety of constructions.

Powerful output, great comfort
In large rooms such as exhibition halls or airport terminals, providing
the desired comfort is always a technical challenge. High flow rates
have to be distributed into the room in such a way that the visitors
always have a fresh atmosphere without draughts independent of the
number of people and the current outdoor temperature. TROX masters
this challenge mainly using cleverly positioned jet nozzles that can blow
fresh air into the room without draughts.

Human beings are one of the biggest sources of humidity
indoors. We lose half a litre of water into the environment
each day through our skin alone.
Too much humidity makes us feel unwell and minimises
our ability to work. At room temperatures of 20 24C,
the body radiates about 20 35% of its excess heat by
evaporating sweat on the skins surface. As the
temperature rises, our sweat production increases as well,
and our cardiac and circulatory problems worsen. At
relative humidity levels of 60 70 % and temperatures
above 25C, we feel that the air is sticky and oppressive,
and our ability to work well falls to a minimum.

Air-water systems
The new home of the European Investment Bank inLuxembourg
In the summer of 2008, the European Investment Bank (EIB) formally
opened its new home in Luxembourg. In the building having a double
faade, conservator, and atria, the approximately 1,600 employees of
the bank manage the constantly growing financing volume in the
27 EU member states and 173 partner countries.
In view of the pending climatic change and increasing energy costs,
the EIB has been aiming for environmental certification for the
evaluation of the ecological qualities of the new building from the
beginning. The result was particularly high requirements on the
environmental compatibility of the ventilation technology used.
At the same time, the most demanding requirements on further criteria
such as air quality, comfort, noise level, flexibility, spatial
requirements, maintenance-friendliness, and costs were to be met.
Thanks to the early involvement of TROX engineers, an extremely
economical ventilation concept consisting of 1,800 underfloorinduction diffusers (BID) was realised. Integrated unnoticeably into
the rooms architecture, these underfloor induction diffusers enable
the use of economical air-water systems, even in room-high glazed
buildings. The decision to use TROX underfloor induction diffusers
paid off. The new EIB building was the first building on continental
Europe to be evaluated as Very Good according to the particularly
comprehensive BREEAM environmental certification method.

Individual system design
Air-water systems use heat exchangers to cool and/or heat indoor air
by means of water-based heat exchangers. The system saves energy
because it takes less power to transport heat away in water than in air.
Air-water systems can be installed in open or suspended ceilings and
are very well suited for refurbishment projects. We differentiate
between active and passive chilled beams.
COMBEAM or multi-service chilled beams, the multifunctional air-water
systems from TROX, not only provide the normal heating, cooling and
ventilation functions, but can also be equipped with extra building
services, enabling space-saving integration of lighting, smoke
detectors, loudspeakers and sprinkler systems. COMBEAMs can also be
designed in the form of design elements to accentuate a buildings
architecture, for example, as ceiling sails or as inconspicuous ceiling
installations. The option of smooth integration into centralised buil-
ding communication and control systems is also possible.

Active air-water systems
In the case of active air-water systems, fresh air is
supplied to rooms from the central plant in addition to
water cooling. In comparison to pure air systems, the
fresh air volume required for a persons well-being can
be reduced to one-third. Because the system is based on
the principle of induction, no extra fans are necessary to
transport the air, thus saving energy and reducing noise
to an absolute minimum. Active air-water systems are
mostly called active chilled beams. These systems save
space because they allow you to reduce the size of the
central plant systems and supply ducts, and theirinstallation height is very low. They are operationally
reliable and low-maintenance because they do not
contain any moving parts. They run in both cooling and
heating mode, which means you do not need to install
extra static heaters.

The Laimer Wrfel building in Munich, Germany
In the Laim quarter of Munich near the downtown area, the Laimer
Wrfel (Cube of Laim) is a contemporary office building characterised
by its efficient use of space and individuality. The building has eleven
upper floors with about 1,900 m2 gross floor area and a multifunctional
circular floor, which also has a convention area and casino in addition to
shops.
Large plant rooms inside the building and branched, space-consuming
air duct works are made superfluous by the use of decentralised faade
ventilation units, thus increasing useful floor space.
The decentralised ventilation units of TROX/FSL are also designed to
save energy and be maintenance friendly, whereby the operating costs
are minimised.
At an early construction stage, 1,600 frames were integrated into the
outer faade. 800 frames were equipped with decentralised ventilation
units. They filter the supply air, provide for, ventilation, and heat reco-
very, and heator cool. To achieve the required heating and coolingcapacities, 540 additional frames were equipped with secondary air units
that can heat or cool the indoor air during pure secondary air operation.
The other 260 frames casings act as a reserve and are initially only
equipped with insulation boxes for noise and heat insulation.
They can later be retrofitted with TROX/FSL ventilation units.
The frame type of construction makes it possible to react to changes in
use in the office building in an fast, cost-effective manner.

More individuality with minimised investment
and energy costs
In our decentralised faade system ventilation (FSL) solution, we
integrate sound-absorbing ventilation units into a buildings exterior.
These units can be installed under sills or into walls or false floors.
They discharge fresh air into rooms and/or exhaust air out along the
shortest possible route.
Both in construction and in retrofitting, TROX decentralised, individually
controllable ventilation systems offer a rich variety of design options
for ventilating a building. Clients can install a complete decentralised
ventilation system or combine the decentralised supply air system with
a central extract air system. The product variation ranges from simple
flow devices to complex systems with heating and cooling functions
and integrated individual room regulation (FSL-CONTROL).
Decentralised ventilation systems provide numerous advantages.
Individual users can adjust the air quality and room temperature in
their rooms according to their own individual tastes. For investors,
TROX systems are economical, energy-saving and, above all, flexible
solutions that can be re-adapted at any time with very little work to
suit change of use.
In developing decentralised ventilation units, TROX takes its inspiration
from the inventiveness and design resourcefulness of architects to find
solutions in which functionality and design merge into an ideal whole.
With our cost-efficient prefabrication of faade elements, TROX
provides investors with integral construction, reduced installation
times and reduced interfaces.

Creative solutions for the refurbishment of
existing buildingsOffice complex in Frankfurt am Main, Germany
Existing standard solutions in ventilation technology can often not be
used for the refurbishment of existing buildings. Here, companies that
can make state-of-the-art technology usable in traditional architecture
with creativity and flexibility are in demand.
In this area, TROX/FSL has been able to prove its capabilities, especially
during the refurbishment of an office complex in Frankfurt. For the
refurbishment of the air conditioning system of Feldbergstrae 35,a building in which the German representative of the British National
Westminster Bank AG has its headquarters, TROX developed a special
ventilation solution between the sill and the ceiling together with the
building owners and architect.
The spatial conditions and usage plans required a ventilation concept
that could make do without a horizontal air distribution system. Only
in this way could the setup of combination and open-plan offices
continue to be possible. In the research and development laboratory of
TROX/FSL, extensive flow tests were performed to meet the projectrequirements.
The advantage in the use of decentralised units was that no suspended
ceilings were required for ducts. The high flexibility through the single
room control and user-adapted settlement possibilities were an
additional advantage. Further examples for the decentralised sill
ventilation solutions of TROX/FSL are the Imtech Haus in Hamburg,
the Laimer Wrfel in Munich, and the Lighttower in Frankfurt/Main.

Complex refurbishment projects confront planners of the technical
building equipment with sophisticated problems. Here, a special focus
is on optimum, modern air conditioning and ventilation technology. In
the process, decentralised ventilation units are increasingly forming
the starting point for innovative solutions since they offer great
freedom for design and fulfil modern usage requirements.
A decisive advantage lies in the lack of duct work. Decentralised
ventilation units are installed near or into the outer faade so that the
ventilation of the stories takes place directly via the outer faade. Thisleads to short transport distances with low pressure losses. At the
same time, the faade becomes an active component that can assume
further air conditioning functions.
Through the preassembly of individual components or complete,
multifunctional faade modules at the manufacturers factory, the
assembly and installation work on-site is strongly reduced.
If the user is not present, the units switch to standby mode or they are
switched off. The energy required for operation can be determined
simply so that the energy costs can be settled based on consumption.This motivates the users to use energy more sparingly since they can
actively sink their individual operating costs in this manner.
Supplementary air conditioning systemsIn many indoor climate concepts, ventilation systems are supplemented
by additional systems to achieve high and better comfort. Chilled
ceilings, for example, are particularly well suited for dissipating higher
thermal loads.
Decentralised ventilation -
a clever refurbishment alternative
Water as an energy-carryingmedium
FSL units dissipate thermal loads using an
air-water heat exchanger. Water as an
energy-carrying medium has a high specific
heating capacity and lower specific volume
than air. In comparison with a given air flow
rate, the same thermal load can be dissipa-ted as with a lower water rate flow. As a
result, the cross-sections of the transport
lines can be reduced.
This and the elimination of the duct works
can considerably reduce the transport energy
expended.

Fire damper in Moses Mabhida Stadium Durban,
South Africa
In Durban on the east coast of South Africa, the Moses Mabhida
Stadium is currently being built for the 2010 Football World Cup. It is
the second largest stadium of the Football World Cup 2010 and has
room for 70,000 spectators. Two large steel arches span the stadium
roof at a height of about 104 metres.
This skywalk, which can be reached by a cable car and a stairway with
550 steps, offers a spectacular view of the city and the Indian Ocean.
In addition to the athletic facilities, the stadium has a sports museum
and a sports institute. After completion, the stadium forms the focus
of the planned Kings Park athletic quarter.
In such large public buildings, special attention is always paid to fire
and smoke protection. This particularly applies for football stadiums in
which the safety of several thousand people must be guaranteed even
in case of a fire. In addition to numerous other components for
ventilation and air conditioning, TROX supplies fire dampers for the
high-prestige new construction project in South Africa.

Fire and smoke protection components
Fire dampers have to close after a certain temperature is
reached, sealing off sections of a building to prevent the
spreading of fire and smoke. To prevent smoke from spreading
at temperatures below the temperature that triggers the
thermal release, fire dampers can also be closed by optionalsmoke detectors. Fire dampers require approval. TROX provides
the right fire damper with general building inspectorate
licence for every installation situation.

More than 80% of the deaths that occur in fires are due
to smoke poisoning. In the toxic smoke, people lose
consciousness after only two to three breaths.Our lungs cannot withstand much, especially in conjunc-
tion with high temperatures; they start to become
damaged at 65C.
In nine out of ten cases, fires undergo a relatively long
initial smoldering phase in which they produce a great
deal of smoke but relatively little heat. 10 kg of foam, for
example, will produce a volume of flue and fire gases of
25,000 m3. Intact, well-coordinated fire safety systems
and modern building communication and control systems
will detect fires early, prevent smoke from spreadingwithin the building and exhaust the flue gas.

Solstice cruise ships of the Celebrity Cruise
For years, the Meyer shipyard has been building luxury liners for
exclusive cruises for the American shipping company Celebrity Cruise.
With Celebrity Solstice, which started its maiden voyage at the end of
2008, and its sister ships Celebrity Equinox (completion in 2009) and
Celebrity Eclipse (completion in 2010), the Celebrity Cruisess largest
and most luxurious ships ever are being built. Every ship is 315 metres
long and has room for 2,800 passengers.
More than 80% of the fully air-conditioned cabins have a balcony.
Wellness areas, spa landscapes, exquisite restaurants, and stages
provide for the well-being and entertainment of the passengers.
A ship places other demands on indoor ventilation and air conditioning
technology than a building. When the Solstice class luxury liners sail
the seven seas at 24 knots in every wind and weather and set anchor
in all climatic zones, the passengers on board should always enjoy a
consistently pleasant climate. For this reason, among other things,
particularly flexible volume flow control is needed. TROX has solved
this task very well with air terminal units of the Type RN,
RN stainless steel, and EN. In addition to the required flexibility, TROX
was also able to reduce the power consumption of the air conditioning
and ventilation system considerably.

This type of controller eliminates conventional balancing dampers and thus the
time-consuming and expensive work of balancing and adjusting the flow rates in
the building. With Types RN and EN controllers, the desired flow rate can be sim-ply adjusted manually using the scale located on the outside of the unit. These
air terminal units were designed for constant flow rates but are also available
with motorised flow rate adjustment.
The casing and the damper blade are made of galvanised sheet steel. In the case
of the Type VFC, the damper blade is made of plastic. The controllers are gene-
rally maintenance free. The plastic Type VFL volume flow limiter is easy to insert
into circular ducts. It limits the flow rate to the set value and maintains it at a
constant level within a close tolerances when changes in pressure occur.

Shut-off dampers are for ventilation systems in which areas
have to be isolated for certain operating situations for safety
reasons. Multileaf dampers are used to isolate and restrict the
air flow in ducts and other openings. External louvres providegood protection to keep rain, leaves, and birds from getting
into the supply and exhaust openings of ventilation systems.
Pressure relief dampers and non-return dampers are used to
isolate individual sections in ventilation systems.
When the fan is running, the blades open; the degree of
opening depends on the air velocity through the unit.
