Vacuum Technology

Kloben vacuum collectors work all year long, even in winter and with unfavorable weather conditions.

The difference between vacuum collectors and flat panels is that vacuum collectors allow the capture of the radiation indirectly. This is possible also thanks to the special aluminium foil called CPC (Compound Parabolic Concentrator), that reflects more than 90% of the available light.

A system with vacuum tube collector is more efficient, with higher performance, more economical and environmental friendly.
