The receiver is a key component of a parabolic trough power plant. Several test benches are operated at the QUARZ-Center for the characterization of the properties of parabolic trough receivers.
ThermoRec: Thermal loss (heat loss) measurement test bench
ElliRec: Elliptical linear focus sun simulator receiver test bench
Kontas: Outdoor rotary test bench designed for the characterization of parabolic trough modules, also used for component testing of receivers and mirrors
Overheating Test Bench: The overheating test bench is used for the overheating of parabolic trough receivers. Overheating of the absorber incluces accelerated aging of the absorber coating.
Bellow Fatigue Test Bench: In this test bench the glass envelope of the receiver is fixed and the absorber tube is pushed back and forth.
