CC Air Handling Units For optimized air quality
Fläkt Woods experience – at your service
Applications BUILDINGS
Fläkt Woods was formed by combining two of the world’s leaders in the air management business – Fläkt and Woods Air Movement. Since the merger, SEMCO, an American based company, has also joined the group.
• Fläkt carries a broad technology base covering air climate systems for buildings and air movement systems for industry. • Woods is the leader in axial fans for air movement for commercial and industrial applications. • SEMCO brings to the group innovations like desiccant wheels, for increased energy efficiency. • In 2008, Fläkt Woods accquired the AHU specialist Airchal in France. Fläkt Woods Group has the capability of providing its customers with application specific solutions and unparalleled levels of service worldwide.
Airchal, based in Amiens, France, is specialized in manufacturing high-
end air handling units. The expertise of the company, combined with the means and the vision of Fläkt Woods Group, confers Fläkt Woods great advantages in term of fabrication quality and capacity of developing innovative solutions regarding performances and energy efficency.
Airchal offers a range of air handling units suitable for comfort application or industrial air treatment. Thanks to a wide range of components to choose from and a well known experience, Airchal has the capacity to match the standard of modern air movement as well as the specific needs of the customers.
The CC range is the right choice for commercial buildings, offices and hotels even in aggressive environments. The air treatment for these applications is an issue since the indoor climate influences the wellness and productivity of employees. Right indoor quality The CC AHU supplies air with the right temperature, humidity rate and filtration. With optimum LCC Right conception for easy maintenance. Energy savings thanks to Eff1 motor, high performance fans and wheel in order to recover heat as well as cooling and humidity. Easy to install and to adapt to the building Indoor or outdoor unit. Wide range of sizes to adapt the footprint to the technical rooms.
EUROVENT RESULTS
The Clean Concept range handles air flows from 2000 to 250 000 m /h. This modular conception follows the highest requests for cleanability, washability and maintenance easiness. The range has been designed for hospital, micro-electronic, pharmaceutical and food industries. 3

The humidity rate is critical for applications such as pharmaceutical, chemical or paper industries. To meet the restrictive demands, dehumidification wheels are integrated in the AHU. These systems, based on adsorption principle, can provide air with very low humidity rate.

From hygienic applications... HOSPITAL, PHARMACEUTICAL INDUSTRY AND MICRO ELECTRONICS For a hospital to operate at it’s maximum potential, it has to have all systems working at the optimum. This not only applies to staff, communications and life support systems, but also to pipework, cleaning and ventilation systems. In the pharmaceutical or micro electronics applications, the air treatment will directly influence the productivity. The air handling unit, the heart of the system, has to meet the high requirements. The material of components and the design have to be carefully worked out to facilitate both cleanability and maintenance.
Fläkt Woods Group has the widest range of fans on the market - CENTRIFLOW PLUS® plenum fan, now available with EFF1 integrated motors or EC motors - High pressure fan
Fully welded HEPA filter frame with DOP test device as accessory Secure fixation of HEPA filter
The unit floor is easy to clean and is developed to quickly drain the wash water Standard bottom in galvanized, painted or Stainless steel Bottom with 3 slopes and water drain in the center of the AHU Bottom made of trays for an optimum washability
...to applications with low temperatures FOOD The food industry is a complex application, because it usually combines strict hygiene levels with low temperatures. Airchal produces air handling units with high standard finishing to avoid condensation and to guarantee easy maintenance and cleaning.

Rotary heat exchanger manufactured by Fläkt Woods
ECONET® SYSTEM The components in Fläkt Woods’ innovative Econet system are connected together to provide a more reliable and more efficient AHU system. Heat recovery, heating and cooling are integrated into a common circuit as heating/cooling coils, pumps, valves, pipe systems, insulation, etc. The result is a shorter and more compact ventilation unit. This is highly beneficial from an environmental point of view because much less energy is used to transport the air through unnecessary components. Further development of the principle of energy recovery has also led to increases in efficiency of 50% compared with traditional coil recovery systems. Econet is patented by Fläkt Woods and has been installed in more than 1000 sites in Europe.
No risk of odour/bacteria transfer Supply and exhaust air units can be separated from each other Constantly optimised energy recovery Pump with sensors and frequency converter Exceptionally low temperature requirement for hot water Chilled water can be as high as 12°C Ideal for use with renewable energy resources Can recover cooling in summer months Ideal for indirect evaporative cooling Compact size for shorter AHUs Low Life Cycle Cost (LCC)
Integrated advantages A carefully designed system can achieve more than the sum of the integral parts. High-performing components are an obvious starting point. But it is by combining products into a system, utilizing smart controls, one can achieve the best energy solutions. Fläkt Woods develops and produces components as well as design systems. That’s why we can combine the parts into harmonic overall solutions.

Energy-efficient Chillers
Within the industry we use an analysis approach called “Life Cycle Cost“ when designing ventilation systems. It balances the cost of better components and smarter system control with savings in maintenance and energy costs over the systems life time. Not surprisingly a smarter system comes out on top. About 85% of the life time cost is typically energy costs, 10% initial investment and 5% maintenance.
