Solar Evacuated Tube, ONOSI-G2

• Product:
  Solar Evacuated Tube
  
  
• Model Number:
  ONOSI-G2
  
  
• Description:
  Heat pipe is a kind of cooper pipe with inner anti-freezing inorganic working medium, it works well even at an ambient temperature -45 ℃， and it possesses characteristics such as long lifespan (more than 15 years), anti-insolation(250 ℃), anti-freezing (-45 ℃), low start-up temperature (>=30 ℃), and a high thermal transmission coefficient (10000 times comparing with pure copper), it is a real special heat pipe suiting to be used in solar field.
  
  The vacumm tube is made of high borosilicate glass. In the inner wall, there're 12 lays selective aborsption coating. These make vacuum tube have high performance of absorptance and low reflection ratio. Through the interlayer, vacuum has a unique effect of thermo, with its temperature up to 380 ℃ of idle sunning, performaing a strong heating ability.
