With increasing length of the OLOID-body the circulation power increases and other applications in liquids arise where a higher energy density is needed for circulation of liquids with solids content (e.g.: activated sludge, cattle manure, etc.). At the moment, we have the size classes OLOID Type 200; OLOID Type 400 and OLOID Type 600.
As well as the OLOIDS Type 200 and 400 as a solar model OLOID Type 200 / 400 K DC Solar.

And to the overview with the most important technical data in a comparison.

And the solar OLOIDS OLOID Type 200 / 400 K DC Solar and the technical data:
