Ebm-papst: DC axial fans cooling main mirror of the telescope

View in almost infinite widths

So fascinating, so far away: about 1,500 light years away from earth, the Orion Nebula with its huge hydrogen clouds is the ideal birthplace for new Stars. Compact fans from Ebm-papst cool the main mirror of the telescope of the observatory Weikersheim and thus enable the gaze into almost infinite distances.

A glimpse of the Earth on this unique spectacle enables a Richtey-Chrétien telescope of the company Alluna optics, which stands in the observatory in Weikersheim.

Better visibility thanks to compact fan

Three compact fans from Ebm-papst are also decisive for a clear view of the starry Sky. These are located directly behind the main mirror of the telescope, from there cool the mirror before using the telescope at ambient temperature. In addition, they prevent the honeycombing of the air when heat rises from the mirror through continuous airflow during use.
