SHCMV tube is mainly assembled with heat-pipe, borosilicate glass tube, heat-collecting plates, metal cover, getter, heat exchanging end and aluminum safety-protection cap, etc. The magnetic-control sputtering selective absorptive coatings on the heat-collecting plates has a high absorption coefficient of more than 94%, and the emission coefficient around 8%. The vacuum degree in the borosilicate glass tube is more than 5× 10-3Pa, equipped with long effective air degassers to keep the setting vacuum degree inside the tube a constant.

Novasol-Energy's NSC 70x1700 collectors are certified by standards EN12975 and Solar Keymark and have the eligibility for the tax credit. This pressurized system consists of high performance super conduction vacuum tubes with 70 mm diameter and 1700 mm length. They have the distinction of having more resistant tubes (2.5mm thick). In addition, the copper rod is welded to the glass to maintain the vacuum inside and therefore increases the life expectancy of the product. These collectors are particularly suited to the less sunny area because they demonstrate a remarkable performance (even in low sunlight and adverse tilt conditions ). The temperature rises very rapidly and can reach temperatures around 250 ° C within a few minutes.

Features:
1. High thermal efficiency, long service, advanced method of heat exchange.
2. Low thermal capacitance of the quick start. It can rise and produce energy in two minutes.
3. High-temperature slow burning up to 250 ° C.
4. The water does not flow in vacuum tubes.
5. Antifreeze resistant to hail.
