SysColl

Factory made system and collector testing facility

For certification in many markets, performance of the complete factory made system (for example thermosiphon systems) plays an equally important role as collector performance.

Our SysColl test stand is a combined test facility for performance testing of both solar collectors and solar thermal systems. This allows you to take advantage of a flexible two in one test solution.

The entire test facility is constructed in our factory in Germany and shipped ready-for-testing to customers around the world. If a suitable building is not available, we offer a standalone solution installed in an air conditioned container.
