Greenland Systems vacuum tubes (evacuated tubes) were developed in Germany by Daimler-Benz Aerospace, with support from UNDP, in 1986. Over ten years of co-operative research and development by Sino-German experts have resulted in today's cutting edge design and superior solar performance.
Ideal for domestic installations, Greenland Systems vacuum tubes are also readily suited for OEM manufacturers and can be used for various kinds of commerical and industrial applications. The absorber and heat pipe are mounted in a highly stable borosilicate vacuum glass tube. This prevents damage and the heat loss that occurs in conventional flat plate solar collector. The absorber is sputtered with aluminium nitride selective coating to ensure high absorption and highest efficiencies - even on cloudy days.
