Ziehl-Abegg has extended its unique range of innovative FE2owlet model series to include further diameters, enabling condenser performance improvements in terms of increased efficiencies and reduced noise levels.
Energy efficiency is becoming increasingly important in the design of air conditioning and refrigeration equipment. To enable designers to address all energy efficiency issues, Ziehl-Abegg offers a variety of systems solutions, including highly efficient EC (Electronic Commutation) technology. In doing so, Ziehl-Abegg is perfectly positioned to assist designers and Consultants in their quest to comply with regulatory and competitive requirements.
FE2owlet fans are gaining in popularity with air cooled chiller applications, remote air cooled condenser applications and dry coolers with EC motor variants enabling owners to realise major energy expenditure savings.
Furthermore, in cooler type applications, EC fans present the additional benefit of radiating less heat from the motor compared with an AC equivalent, reducing plant heat loads, enabling higher plant efficiencies.
New standards in fan technology have been set here by the innovative Ziehl-Abegg FE2owlet fans with AC- and EC motors. These new standards are further enhanced with the use of guide vanes in increase the ‘throw’ of the fans, available for fans with diameters from 450mm to 800mm.
EC technology however is not the panacea for all speed control requirements, and Ziehl-Abegg’s Fcontrol frequency inverter presents the perfect solution for speed controlling AC motors (for both fan applications and non-fan applications). The integrated all-pole sinusoidal filtration enables inverter speed control of parallel motors, significantly reduces the stress applied to AC motor windings, and guarantees maximum motor life.
Advances in heat-pump technology, the resulting energy saving opportunities, and incentives for the use of heat-pumps, have resulted in an explosion in their popularity. Ziehl-Abegg’s state-of-the-art high efficiency FE2owlet axial fans and Vpro centrifugal fans both have innovative profiled blade geometry and low noise emissions. They are ideally suited to air to air and air to water heat-pump applications, where noise levels are critical and high efficiency is a prerequisite. The result is that these fans are applied increasingly in the heat-pump industry.
Take advantage of all these benefits and put your trust in Ziehl-Abegg system components that go together perfectly. See for yourself the new designs and innovations at Chillventa, Nuremberg, 15th to 17th October 2008, Hall 7, stand 7-110.

Given the current trend for energy costs to rise at rates which appear to be almost exponential, air conditioning and ventilation systems are coming under close scrutiny, particularly in terms of efficiencies and coefficients of performance. Add to this the requirements of Building Regulations and the much talked about Energy Using Products Directive, fan efficiencies are a major issue now.
In air conditioning and ventilation systems, fans can account for a significant proportion of the energy consumed. It therefore makes sense to install new equipment and/or retrofit existing equipment with fans having the highest possible efficiency.
Considering Air Handling Units and Air Cooled Condensers / Dry Coolers, the types of fans used are normally centrifugal and axial respectively, and optimisation is possible in both instances.

Heat pumps are a heating technology with a future. An ever more important role is played by the air-water heat pump. Together with this solution, modern fans can offer many advantages.
With the Vpro the engineers at Ziehl-Abegg have come up with a new centrifugal fan developed specifically in accordance with the basic principles of acoustics technology, excel because of their high efficiency, low noise and rotational tone emissions. The Vpro centrifugal fan is particularly well-suited for service in air-water heat pumps, in which high volume flow rates with low noise levels and medium pressure differences are required.
For heat pumps with a lower pressure drop, Ziehl-Abegg recommends there innovative FE2owlet axial fans. This unique blade design is the result of the direct implementation of the latest bionic and aeroacoustics knowledge. In matters of energy efficiency and sound emission the FE2owlet comes very close to the perfect fan and thus predestinated for noise-sensitive environments.
