BIOMIMETIC CONCEPTS

It is no coincidence that the development department at ZIEHL-ABEGG transposes findings or biological processes from nature into technical products. For millions of years nature has had time to perfect its processes and developments. By transferring natural phenomena to today's technology, it is important to use perfection in a way that makes it as sustainable and efficient as possible. At ZIEHL-ABEGG we combine our intelligent technology with the biomimetic knowledge of nature and thus receive the key for high-tech products of the future.

FE3owlet

The world’s only biomimetic blade concept for unsurpassed performance
The successful adaptation of essential findings from the wing shape of the nocturnal barn owl and other biomimetic concepts to the development of the wing profile has resulted in a unique wing design worldwide. Thanks to the profiled, sickle-shaped blades of the axial fan and a serrated rear edge, the FE3owlet delivers incredibly efficient flow behaviour, greater air volumes and drastically reduced noise levels. In addition, the blade shape of the fan at the blade leading edge is inspired by biomimicry and the corrugated edge allows an optimal airflow.

FE2owlet

Biomimetic blade design: Axial fan with globally unique biomimetic blades
Essential findings from the shape of the wings of a nocturnal barn owl led to development of the FE2owlet fan. The flow noise in flight was the determining feature. The successful adaptation of these essential insights to the development of the FE2owlet blade profile – with a profiled, sickle-shaped blade and a serrated trailing edge – creates a globally unique blade design with incredibly efficient flow characteristics, larger air volumes and drastically reduced noise development than in comparable fans.

ZAbluefin

Blue steel with depth: biomimetic, corrugated, extremely efficient, super-silent
Based on further biomimetic concepts from nature, the ZIEHL-ABEGG engineers and technicians adapted the findings into the new technology of the ZAbluefin. Especially the corrugated front edge provides optimum airflow even in disturbed air conditions - the impeller benefits and therefore has a significantly better air performance. Also for example the V-shaped contour of the trailing edge of the blades also reduces possible flow tear-off at the cover and bottom plate. This permits using the fan in many pressure range requirements.

ZAvblue

The tree whisperer: biomimetic radial fan for more airflow at smaller diameters
Based on the tried and tested biomimetic blade concept of the Cpro impeller, insights from the growth behaviour of trees – with branches that resist winds and weather – complete the biomimetic blade design of the ZAvblue in the attachment and output of the cover and bottom discs. This successful adaptation in technical situations leads to an optimised efficiency at high volume flows, combined with a broad efficiency range. The highly efficient centrifugal fan ZAvblue with its biomimetic light-weight construction is a perfect symbiosis of high-tech and nature with high efficiency.

ZApilot

The new fan system for even higher efficiency
The search for a stable, material-saving and light-weight construction led the developers of ZIEHL-ABEGG to study bees. They build their honeycombs extremely stable and yet very light in weight. Any stress is distributed across the entire construction through the walls to prevent point loads. The hexagonal geometry gives the construction the required stability, while the hollow spaces save resources. The honeycomb structure of the airflow-optimised suspension thus ensures maximum stability while also being cost-optimised by saving material.
