Movement by Perfection The Royal League in ventilation, control and drive technology ECblue The energy saver amongst fans

No one can get passed the Royal League Z I E H L - A B E G G s t a n d s f o r m o v e m e n t b y p e r f e c tion in the ventilation technology, control technology and drive technology sectors for more than 100 years. What started with the invention of the first external rotor motor by Emil Ziehl is now being carried on at the company’s sites around the world. We are the pioneers, masterminds and developers of technologies for the future which more than satisfy all demands to preserve an environment worth living in and to meet all our customers’ requirements and wishes. Think ahead to the...

From fans and motors to matching control technology Our unique selling point – your advantage What is important to us is to correctly match our systems to your exact needs. Be it refrigeration, air conditioning, use in manufacturing processes or anywhere else - we reliably move air wherever it is required and at the right time. At the headquarters in Künzelsau more than 100 engineers and technicians work in one of the most modern technology centres of this kind. We supply the highest quality standards with the world‘s largest air and noise testbench for fans, which can completely mask...

The principle Ingeniously simple – highly efficient – exceedingly reliable ECblue The new economic solution Ingeniously simple functionality Compact, cutting-edge technology, user-friendly and simple – these are the main criteria we set for the development of the ECblue series. Meet ECblue and convince yourself of the result! Maximum efficiency – Minimum power consumption Nowadays, saving energy is more important than ever. Energy costs are exploding; the global climate is changing. Fans with ECblue technology will help lower your operating costs. Our environment will also appreciate the...

EC technology history Since the middle of the 80’s, ZIEHL-ABEGG has been performing pioneering work in the development and manufacturing of efficient EC external rotor motors for fans. Nearly 30 years later, a new era is dawning in EC technology: ECblue. ECblue is ZIEHL-ABEGG’s third generation of EC motors. This latest EC technology is setting new standards for control, efficiency and reliability. EC means electronically commutated. EC motors are synchronous electric motors which have electronic commutation systems, rather than mechanical commutators and brushes. The speed of the fans or...

ECblue – Efficient Presently, saving energy is more important than ever. Energy costs are exploding; the global climate is changing. Fans with ECblue technology will help lower your operating costs. Our environment will also appreciate the low power consumption of the ECblue fans – after all, the cleanest energy is the energy that doesn’t need to be generated in the first place! In 2005 the European Union passed the EuP Directive (Energy using Products Directive), which was replaced in 2009 by the ErP Directive (Energy related Products Directive). With this directive the scope was enlarged...

ECblue – Reliable Premium Quality 10 0% of fans are tested and the test data rec orded before they leave the factor y. En c a p s u l a t i o n Enc apsulation is a proc ess of f illing a c omplete electronic assembly with a solid c ompound for resistanc e to shock and vibration, and for exclusion of moisture and c or rosive agents. It also provides much more protection against dust, humidit y and aggressive environments. Bet ter Protection results in another advantage, and that is power densit y. E x tending the life of the electronic s and making it more robust. ZIEHL-ABEGG is testing the...

ECblue – Flexible Add on Modules Wireless programming – standard in ECblue With their modular c onstr uction, the functions in the EC116 and EC152 motor frame size ECblue fans c an be expanded by simply plugging in additional modules. The add - on modu les c an be tailor- made to c over var ious applic ations. This means the ECblue fans have precisely the functions you need. Nothing more and nothing less. Even if the require ments plac ed on the ECblue happen to change later on – no problem. When considering the functionality of the motors, our engineers have taken things one step further....

ECblue – High efficiency low noise A FE2owlet has a noise level around 4 5 dB* *FE2owlet (FN080) calculated at 5m distance at full speed 25 dB Nature outside (feels totally quiet) 14 30 dB Whispering 40 dB Hum of a refrigerator 60 dB Normal conversation w w w.ziehl - abegg.c om

The increase of 3 dB doubles the felt noise level Ziehl-Abegg AG has one of the best noise testrooms world wide. The testroom is AMCA and TÜV certificated. Inside, when all doors are closed, background noise is below 20 dB. It feels abnormally silent.

In the chart you can see the difference between "switching off" and "speed control" with regard to...

How can a speed controlled fan help you to increase your system efficiency? Calculation example 5 0% air f low is needed in a 10 fan condenser ar ray, shut down 5 fans Shut ting down 5 fans leads to a power c onsumption of 5 kW P = (5 * 1 kW ) + (5 * 0 kW ) = 5 kW Reduce all fans to 5 0% The reduction of the fans leads to a power consumption of 1,25 kW Basic dat as: 1 fan has a power c onsumption of 1 kW at 10 0% Law of power c onsumption dependant on speed n n 3 P1 = 10 kW; n1 = 10 0 0 r pm; n2 = 50 0 r pm P = (10 kW / (10 0 0 rpm/50 0 r pm) ³) = (10 kW/8) = 1, 25 kW 75% lower power...
