REFLECTIVE SURFACES
The highly reflecting vega energy specular surfaces are a key component of concentrating solar systems.  They concentrate the solar radiation precisely to achieve extreme energy densites. By using vega energy mirrors with their outstanding  reflecting properties the  performance can be increased significantly  in concentrating parabolic  systems  (CSP) for the generation  of solar  thermal electricity,  or process heat for industrial  applications, air conditioning or sea water  desalination.
High performance material for solar secondary reflectors

Designed to maximize long term output from your fresnel or parabolic based secondary solar thermal system, vega HT and vega TS products represent a further step in Almeco's commitment to developing products for solar energy applications. Using specially developed versions of the vega WR solar reflector product range they offer a combination of high reflectance and temperature resistance to provide maintained performance over the life of the plant.

Almeco has developed a new coating system specifically designed to overcome the temperature limitations which even vega HT faces. Known as vega TS (thermally Stable), it is a modified layer stack which reduces high temperatures reflectance loss to a minimum. 

Accelerated testing of the new product at temperatures up to 500°C has shown that at a working temperature of about 300° C the vega TS product will shine, and shine on.
