The name Ziehl-Abegg stands for pioneering spirit and pole position in terms of technology in ventilation with matched controllers, and drive technology. We recognise our company as a complex entity, with many people, ideas, competences and experiences, from which we - and just as importantly, our customers, benefit every day.
To enable air cooled condensers and dry coolers to benefit from the effects of evaporative cooling, Ziehl-Abegg has developed the UNIcon-Adiabatik control module.
The control module is able to use the integrated temperature or pressure modes of control plus external signals, for system control. If you use the module for example to control fans on condensers, it can activate up to three humidification levels to increase the condenser cooling capacity on hot summer days. Frost protection of the water circuit by blowdown of the system is a standard feature.
Integrated 0-10 V outputs are available for the control of FREvent or ETAvent fans, or for connection to external control devices. The module can be used in further applications through the ability to configure the control inputs and outputs as required. This versatility enables the control module’s use in ventilation systems, agricultural applications and production processes, etc.
London, 3 May 2007. In March 2007, it was announced that Ziehl-Abegg would be a participant in the final round for the „‘Air Movement Product of the Year’ Award during the 2007 h&v news Awards contest. Ziehl-Abegg participated in this competition with the EC variant of the FE2owlet axial fan (EC = electronically commutated motor). On 3 May 2007 during a ceremony held in the Grosvenor House Hotel in Park Lane, London, in the presence of 1,000 guests from the heating and ventilation industry, the „FE2owlet-ETAvent“ was named as the winner of the prestigious „Air Movement Product of the Year“ Award. According to the jury, "the manner in which this product takes advantage of the forces of nature should move us to rethink the accepted ways of designing all impeller geometries". The h&v news Award event occurs annually in the United Kingdom.
Manufacturers and service providers for air conditioning products are challenged to face the competition with new and innovative products and services in a total of 18 categories. The judges choose the three finalists in each category and the winners are announced during the h&v news Award Ceremony.
Naturally, Ziehl-Abegg UK, the English marketing subsidiary of Ziehl-Abegg AG Künzelsau (Germany), participated in this contest. The FE2owlet axial fan with the ETAvent EC drive was chosen as the Ziehl-Abegg entrant in the ‘Air Movement Product of the Year’ category. h&v news confronts the candidates with tough criteria for the ‘Air Movement Product of the Year’: along with aesthetic aspects, the energy efficiency in particular is put under the microscope, and has to be verified with empirically obtained test data.
The information submitted by Ziehl-Abegg UK in the FE2owlet-ETAvent application emphasised the influence of bionic and aeronautical principles during the development stage. Ralf Neumeier, chief of axial fan development at Ziehl-Abegg commented: „Learning from nature means careful observation, discernment and comprehension. Over the course of time, birds’ flying behaviour has evolved perfectly. They use a minimum of energy to create enough thrust to generate sufficient lift. It is especially the owl, compared to other birds, that is distinguished by its quiet flight behaviour. The fibrous feather structure of the trailing edges of their wings was technically copied in the new development. On top of that, so-called winglets were used that can be found in a multitude of aeronautical applications and which enable the fan to achieve even more highly-efficient flow characteristics“. The judges were informed that these characteristics, combined with the use of the most efficient EC motor in the market, resulted in a pa
