Strips "Sunstrip" with integrated tube More than 20 years as cooperation partner to the solar collector industry have made Sunstrip's absorber strips the most widely distributed on the market and extremely well tested products. Absorptive power is high and emissions very low thanks to the sputtering method for selective surface coating. This together with the superior flange efficiency gives excellent performance. |
