Heat pipe vacuum tube: 58mm*1800mm / 47 mm*1500mm
  • Vacuum tube absorbs the solar radiation and transforms it into heat energy. Then it transfers the energy to the heat tube, and the heat tube transfers it to the working media.

  • Pressure- bearing operation: high pressure- bearing technology does not limit installation height, heated water operate under high pressure, has high current and has comfortable bath: vacuum tube does not leak water, does not store scale and has not tube explosion. The whole machine has strong anti- freezing capability, has more stable operation.

  • Higher heat efficiency: advanced heat transferring style of the heat pipe, excellent selective absorb coating and perfect combination with high vacuum heat preservation.
    Wide applicable range: as the heat pipe has less heat capacity, 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 lowing of heat efficiency due to frost cracking or scaling.

  • Each individual tube can work independently, and the whole machine can still work if individual tube is damaged. The service life of the heat pipe can be longer than 15 years.
