Product Description

S C Tube Features:
High solar-thermal conversion and low heat loss

Stable advanced coating up to 380

High level vacuum ensure operation under cold weather
Advanced solar selective coatings
Advanced solar selective coatings employ two patent technologies:
(1) Double cermet film structure with the highest photothermal efficiency
(2) Metal-Aluminum nitride cermet (M-AlN) materials deposited by a novel sputtering technology.

The typical film structure of M-AlN cermet selective surfaces
Schematically shown in the figure one.
