TUBO II

TUBO II C has parabolic reflectors behind the tubes and is made for pitched and flat roofs. TUBO II T has no reflectors and is made for facades or for mounting flat on a flat roof.

Consolar rates TUBO II at 20 to 40% more efficient than flat plate collectors. The manifold sits at the bottom of the collector for frost protection, up to 14 collectors can be connected in one array, and the collectors are Solar Keymark certified.

The vacuum between the inner and outer tubes acts as an excellent insulator so hardly any heat is lost. This makes evacuated tubes especially effective for high temperature hot water systems or where the outside temperature is very cold.
