solar heat pipe-SR1104093

  Solar vacuum tube features 1. Higher heat efficiency: Advanced heat transferring style of the heat pipe, excellent selective absorbent coating and perfect combination with high vacuum heat preservation 2. 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 3. 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 15years. 4. The unique connection between the heat pipe and the vacuum tube can ensure both sealing and replace of damaged glass vacuum tube.

Advantage :

The non-pressurized system is based on the natural circulation-thermosiphon phenomenon. It's the most cost-effectiveness and environmentally friendly way to harness solar energy for hot water applications, which is unsurpassed by any other solar thermal products, for its most high efficiency, low cost, easy installation.
