Motors

Our high-efficiency motors are available in different versions and performance levels. For instance, for our axial and centrifugal fans, we offer both powerful, robust AC motors as well as the latest generation of speed-adjustable EC motors, such as the particularly versatile and quiet ECblue motor from ZIEHL-ABEGG.

We find a fail-safe, durable and economical solution for every need, even in confined installation conditions, extension projects, conversions or (energy-efficient) renovations (retrofit). And because we develop our motors in conjunction with the fans and other components, the finished overall system (ventilation technology, electric drive, control and regulation technology) later works perfectly together – with the highest levels of efficiency at the lowest operating costs.

AC motors with their proven drive concept of a wear-free squirrel-cage rotor motor are not only particularly reliable and compact, but also very flexible. They are inexpensive to purchase, robust and durable and therefore ideally suited, for example, for use in potentially explosive areas or for use in extreme temperatures.

In order to control the speed of an AC motor, a frequency converter must be connected upstream, which can significantly improve the energy efficiency of the motor in the partial load range.

The wider speed range and steplessly variable speed control of EC motors enable precise adjustment of the motor operating point over the entire working range. This means that the fan always delivers exactly the power required, ensuring it works quietly and with a high level of efficiency. EC drives are therefore superior to AC motors, especially in partial load operation: They comply with energy efficiency class IE5 and are therefore pioneering from an ecological and economic perspective.

ZIEHL-ABEGG’s highly efficient EC fans already meet the increasingly stringent requirements of the Ecodesign Directive (ErP) and achieve the high efficiencies prescribed in Europe to protect people, the environment and the climate.

In addition, EC motors can be networked, monitored and digitally controlled with the cost-effective MODBUS bus technology. With ZAbluegalaxy, a secure cloud is available for this purpose, enabling all electrical components of ventilation technology to be managed, analysed and monitored.

With the ZIEHL-ABEGG retrofit programme, upgrading your ventilation systems really pays off – because we know exactly how to achieve major improvements with little effort. When retrofitting with ZIEHL-ABEGG, the existing systems remain unchanged as far as possible; only the old fans and drive systems are replaced by energy-saving, powerful and more controllable components.

Before replacing the fans, we work together with the customer to plan which measures are necessary and sensible to make the existing technology more efficient. The aim of upgrading ventilation systems is usually to permanently save electricity and operating costs and/or to (re)fulfil legal requirements.

ZIEHL-ABEGG fans ensure sufficient fresh air, cold air or the right climate in many industries and areas. When cooling sensitive or perishable goods, fresh food or medicines, the reliability of the refrigeration technology is just as important as its performance. The safety, quality and hygiene of refrigerated products and goods can only be guaranteed at stable temperatures and in uninterrupted cold chains.

Be it medical products, high-performance technical components, fish, meat, vegetables or fresh flowers: Cooling requires fans – for cold rooms and cooling chambers, storage and safe cooling transport from the manufacturer to the end user. Our biomimetic fans for refrigeration systems not only achieve maximum efficiency with minimum electricity costs, but are also particularly quiet, durable and reliable.
