Sunex vacuum tube collectors

The HP 22/30 tube collector from the manufacturer Sunex is produced using 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. Its manufacturing process ensures high operational reliability for heating support. This is further enhanced by the mineral wool insulation and the black aluminum casing of the manifold, which provides maximum protection against the elements. The copper pipe system ensures maximum energy efficiency, and the design guarantees a long service life. Thanks to the heat pipe technology, glass tubes can be easily replaced without draining the system.
