TUBE COLLECTORS TUBO 12 CI mounted on the belgian antarctic research facility TUBO II T installation in Appenzell (CH), SPT TUBO II C & T – innovative tube collectors for large and small installations Vacuum tube collectors for versatile applications With the two new tube collectors TUBO II C with reflectors and TUBO II T without reflectors, a versatile range of applications are possible. While the TUBO II C is usually used for pitched roof and flat-roof systems, the TUBO II T is usually used for facade mounting or horizontal mounting on flat roofs, its main application area. Due to their symmetrical design, both types can also be mounted in landscape, For example on balconies. Flexible use, outstanding design The small module size is suitable for horizontal, vertical, roof-mounted, flat-roof and frame mounting. The TUBO II impresses with its extraordinary design and is one of the lowest profile tube collectors on the market. Giving an aesthetically pleasing appearance. Maximum energy savings thanks to the high collector yield Thanks to the TUBO II C and TUBO  T, a high thermal II  efficiency can be achieved even in the winter half of the year. The vacuum between the tubes gives excellent insulation. This is the main reason for the 20  % – 40  % higher efficiency compared to flat plate collectors. In addition, the light beams are concentrated in the TUBO  C via II  parabolic reflectors. Thus, even with relatively small collector areas, high gains can be achieved. Quality and durability Over 20 years of practical experience are woven in the TUBO II. The used materials are chosen for a long service life. The underslung manifold provides essential advantages: Condensation, which TUBO II T forms in certain weather conditions, can run out of the tube. As a result, the tube can not burst during freezing. In addition this leads to an increased service life of the antifreeze and to particularly low heat losses. Environment The frameless, flat design of the collector minimises elaborate material use and thus energy for production. Double glassed vacuum tubes efficiently replace unnecessary insulation.

LONG DURABILITY DURING HIGH TEMPERATURES TUBO II with connection manifold at the bottom: Increases the lifetime of the antifreeze by quickly evacuating the collector. FROST PROTECTION TUBO II with the manifold at the bottom: In winter, condensing water can simply run out. This ensures frost protection for the glass tubes. LOW HEAT LOSSES TUBO II with connection manifold at the bottom: Lower heat losses due to warm tube end with vacuum insulation.
