Vacuum tube collectors
Sunex vacuum tube collectors
The tube collector type HP 22/30 from the manufacturer Sunex is produced in the so-called HEAT PIPE technology and consists of borosilicate silicon glass
The glass is only 2 mm thick and has a low iron oxide content. This manufacturing process ensures high operational reliability for the heating support system. This is also reflected in the mineral wool and the black aluminum casing of the manifold, which offers maximum protection against weather conditions. The copper pipe system ensures maximum energy generation and the construction ensures maximum service life. Thanks to heat pipe technology, glass tubes can be easily replaced without draining the system.
