Solar evacuated tube, interma-030

Solar evacuated tube
  • Model Number:
    interma-030

  • Description:
    1. higher heat effciency:advanced heat transferring style of the heat pipe,excellent selective absorb coating and prefect combination with high vacuum heat preservation.
    2. Wide applicable rang:as the heat pipe has a capacity of high thermal conductivity,it can be started quickly even under cloudy fine day and collect heat effectively.It can work normally even-30 below degree.As no water in the vacuum tube,it can effectively prevent loeing of heat efficiency due to frost cracking or scaling.
    3. the system can normally work if individual tube is damaged.The service life of the heat pipe can be longer than 15 years
    4. the unique connection between the heat pipe and the vacuum tube can ensure both sealing and replace of damaged glass vacuum tube.
