DLRRI-016
HTF lab
About this facility
The heat transfer fluid laboratory and its testing facilities offer services for the development of new fluids, processes and components as well as for analysing used fluids and components. Focus is on materials that are used in liquid condition like mineral oil, synthetic oils, silicone fluids or molten salt.
Sectors and technologies
Heat transfer fluids for parabolic trough, linear Fresnel, point focussing and electrically heated systems.
