U-pipe vacuum tube collector Unprecedented performance and reliability The VTS is a Calpak collector of unique design using ultrasonic welding of the copper fins on the copper u-pipe thereby providing outstanding performance and reliability.

Innovative characteristics Ultrasonic welding of the copper fins on the copper U-pipe: This contributes to the significant enhancement of thermal conductivity between the copper fins and the copper u-pipes. In addition, the use of copper fins considerably improves the resilience of the collectors to strong thermal shocks Specially designed parabolic reflector (CPC): The carefully calculated radius of the parabolic shape of our reflectors enhances the exploitation of diffused radiation Aluminium header and side profiles: The aluminium profiles used for the header and the side parts of the VTS...
