Use:

Possibility of use in vacuum collectors from various manufacturers.

 Design:

The vacuum tube is made of borosilicate glass. The vacuum between the two layers of glass is an excellent insulator and prevents heat losses. In the process of triple magnetron metallization, an absorber (compound absorbing sun rays and converting them into heat energy) is applied. Additional layers of the absorber are intended to keep as much energy as possible inside the pipes and prevent heat loss through infrared radiation. The new special absorption layer ALN/AIN-SS/CU with the addition of copper is the next generation of absorption layers. The successor of the AL/N/AL layer is characterized by higher efficiency (up to 12%) and excellent absorption properties of direct and diffused radiation. The interior of the vacuum tube can heat up to 300ºC.

outer tube diameter: 58 mm
inner tube diameter: 47 mm
tube length: 1000 mm

Vacuum tubes 58/1800

The collective packaging contains 15 or 20 vacuum tubes.

WE DO NOT DELIVER GLASS VACUUM TUBES THROUGH COURIER COMPANIES. Shipping by courier only on explicit request and the responsibility of the buyer after prepayment.
