Vacuum Tube Collectors can achieve extremely high temperatures, making them more appropriate for commercial and industrial application. The collectors are usually made of parallel rows of transparent glass tubes. air is evacuated, from the space between the two glass tubes to form a vacuum, which eliminates conductive and convective heat loss.

-758kWh/m²/a energy gain.

- copper pipe with "U" shape;

- within the copper pipe flows heat transfer fluid;

- higher heat gain, lower heat loss;

- easy to install;
