Applications
The D type is one of the more specialised impellers in the Multi-Wing range.
With a diameter range of 400mm - 660mm and the broad paddle shaped profile of the fan blades this impeller type is ideal for smaller heat exchanger applications such as
oil coolers, air-cooled condensers and
dry coolers. With fan blades of glass reinforced polyamide this impeller is used in low temperature
evaporator applications as well.
The D type impellers provide the successful combination of high airflow and high-pressure rates at low speeds resulting in low noise levels.
Further, the fact that this impeller type is made up of a modest number of components makes it very cost-effective.
