Clean Air

TROX understands the art of competently handling air like no other company. Since its foundation in 1951, TROX has been developing and manufacturing sophisticated components, units and systems for ventilation and air conditioning as well as for fire protection and smoke control. Dedicated research and development have made TROX a global leader of innovation in these fields.

Application-oriented clean room solutions.

In highly sensitive areas ventilation and air conditioning have to meet specific and extremely stringent requirements. TROX clean room technology meets the highest protection and safety standards, and it is found in many highly sensitive areas such as:

Research facilities, laboratories with fume cupboards, livestock facilities
Ultra clean production environments in the area of life sciences, optics and laser technology, nano technology, and semiconductor production
Operating theatres and sterile areas in hospitals and health care facilities (see TROX application brochure for hospitals)
Rooms that require a special volume flow rate and pressure control, e.g. control rooms and meeting rooms

Comprehensive system solutions

This application brochure deals primarily with the air distribution and air handling in clean rooms. The reliability and safety of a ventilation and air conditioning system depend on effective airflow management, i.e. on the coordinated interaction of all components.

One-stop shop. Complete solutions from a single source.
TROX offers bespoke, complete ventilation and air conditioning solutions from a single source: Air handling units and fans, measurement and control components, and a unique range of aerodynamically optimised air terminal devices, filters, and fire protection and smoke control components all deal with the various stages of the airflow.

Where work safety and the protection of valuable products, people and the environment are priorities, it is of paramount importance that all components of a clean air system complement each other perfectly.

Fewer interfaces, less coordination effort.
The advantages for specialist consultants and HVAC contractors are obvious: one face to the customer – for efficient ventilation and air conditioning systems. The result is a drastic reduction of the usual interface or coordination problems. All ventilation and air conditioning components from TROX are engineered in Germany.

TROX has both the know-how and the necessary expertise to set the highest standards in the field of air distribution for clean rooms. Since 1998 our clean room experts have been members of the standards committees for the EN 1822, EN 14175, DIN 1946 Part 7, and other guidelines and have provided valuable input to these bodies.

Safety for products and processes

Ventilation and air conditioning in clean rooms means, first and foremost, controlling undesired airborne particles. This is why we at TROX have thoroughly examined the measures that reduce or minimise adverse effects on people, products and the environment in order to develop complete solutions. Controlling the diverse, interdependent factors which influence air cleanliness and safety has led to the development of extremely reliable and energy-efficient clean room systems that address the following aspects:

Air treatment, transport, filtration, and discharge: Ensuring a high level of air cleanliness and a good room air quality
Air management: Protecting products, processes, people (highest quality standards for production) and the environment from contaminated air by maintaining the required volume flow rates and balances
Fire protection: Preventing the spread of contaminated air and of fire and smoke through ducting in the event of a fire

Energy efficiency

Demand-based optimisation saves energy.

In most companies today, work does not end at 5 p.m. sharp. This is why many systems are running 24 hours a day, 365 days a year, even though they are really needed only about 50 % of the time. It should, hence, be possible to operate building services effectively but also flexibly, and not necessarily with full power for 24 hours a day.

Air distribution systems from TROX provide intelligent, demand-based volume flow rate control and consequently ensure a high level of energy efficiency. The systems run with full power only when people are working in the factory or in the lab. When a space is not occupied, the air change rate is reduced.

This offers a considerable savings potential over time.

Energy savings potential in existing systems.

When it comes to energy efficiency, ventilation and air conditioning systems have come a long way. This is why a considerable energy savings potential lies dormant in older systems. The modernisation of ventilation and air conditioning systems by suitable measures, e.g. by fitting air handling units with frequency converters or installing VAV terminal units, may reduce the energy requirement of these systems by as much as 40 %. Such investments pay off, often within

only two years.

Increasing efficiency with filters and air handling units.

Filters are supposed to separate particles in the air – and they are an obstacle to the airflow. As the differential pressure increases, the energy efficiency decreases. The goal is minimising the loss. TROX has developed filters that reduce the unavoidable differential pressure increase and hence increase energy

efficiency. TROX offers filter media with extremely fine pleats and aerodynamically optimised filter units that help to save up to 50 % energy.

TROX air handling units are very energy efficient because they are equipped with state-of-the-art heat recovery systems and innovative high-efficiency fans.

TROX Lösungen für die Reinraum-Lufttechnik

Clean solutions start with planning

Comprehensive and flexible solutions for every requirement.

On the following pages we present innovative clean room systems made by TROX. Our goal is to give you ideas for the design and implementation of ventilation and air conditioning systems for clean rooms and to show you options for different ventilation requirements.

The table on the fold-out page lists the relevant standards and guidelines and offers practical design advice with regard to the ventilation and air conditioning of clean rooms. You are then invited to follow the way of the air from the air handling unit to the air terminal devices.

Strategies for clean rooms

Close cooperation leads to innovative room air strategies

Developing and implementing a comprehensive room air conditioning strategy that meets the most critical safety and comfort requirements is only possible through the close cooperation of specialist consultants, HVAC contractors, users and manufacturers, and then from the beginning, i.e. from the design stage onwards. The know-how and the complete TROX product portfolio is, however, also ideally suited for refurbishment projects.

The illustration on the fold-out page shows you how a clean room production facility can be equipped with innovative TROX products and systems.

Air handling

Air management

Air filtration

X-CUBE air handling units
handle volume flow rates of up to 86,000 m³/h (24,000 l/s) for the ventilation and air conditioning of rooms – including filtration, heating, cooling, heat recovery, and humidifying and dehumidifying.

Fire dampers
are certified for all European countries and prevent fire and smoke from spreading through ventilation ducting. The fire area is consequently isolated from other parts of the building.
X-FANS smoke exhaust fans
remove the hazardous fire gases in the event of a fire. Escape routes are kept free from smoke such that the building can be evacuated without any problems.
External weather louvres
protect air conditioning systems against the direct ingress of rain, leaves and birds into fresh air and exhaust air openings.
Multileaf dampers
provide a means for shut-off, and they prevent air from flowing against the intended airflow direction. Combinations of external weather louvres and multileaf dampers or non-return dampers have a dual function.
