• heating water with clean and inexhaustive energy from sunshine;
  • help fighting the overheating of our planet by reducing emission of CO2 ;
  • minimize the consumption of fossil fuels;
  • Seido tubes are made of highly stable borosilicate glass and  sealed safely with the thermo compression technology between metal and glass, all energy transferring parts are installed in vacuum glass tube  so that be protected from harmful  influences of the external environment;
  • operation at low irradiation of 160~200w/㎡, even on a cloudy day;
  • achieve a high temperature up to 120℃ due to the high efficiency;
  • maximum operation pressure of 10 bar ;
  • anti-freezing (dry connection between the glass tube and the manifold);
