Solar Thermal: Solar Collection
We import the Sunda evacuated tube solar collector into Australia. The Sunda Seido evacuated tube is a market leader offering a modular design with great solar thermal efficiency.
Sunda’s Seido evacuated tubes were developed by Sunda and Daimler-Benz Aerospace with support from UNDP in 1986. Over ten years of co-operative research and development by Sino-German experts resulted in today’s design. Sunda’s vacuum tubes are suitable for OEM manufacturers and can be used for various kinds of installations. 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 solar collectors. The absorber is sputtered with aluminium nitride selective coating to ensure high absorption and highest efficiencies even on cloudy days
Sunda solar collectors offer elegant design and efficiency in any application. The collectors are suitable for single unit installations or large-scale installations for heating or air conditioning projects. The heat pipe tubes are not directly connected to the water circle and therefore tubes can easily be replaced or added.
Sunda collectors can be mounted even on smallest areas and verifiably achieve higher temperatures than flat collectors. The high quality manufacturing ensures a lifetime of at least 15 years without loss of efficiency.
