Non Pressurized Unilateral Vacuum Tube Solar Collector

Ateliving Unilateral Vacuum Tubes Solar Collector:

• Vacuum tube type: Common vacuum tube;
• Vacuum tube size: 58x1800mm;
• Vacuum tube quantity: 30 tubes
• Manifold, frame, and stand material: Stainless Steel or Galvanized Steel;
• Tube quantity is optional, BYT model from 15 tubes to 30 tubes, and BYTT model from 30 to 60 tubes.

Separated One-sided Non-pressurized project solar collectors are mainly for large projects. This kind system uses city water pressure to circulate water through whole system. There should be one or some water tanks upper than solar collectors. Its work principle just likes Integrative Non-pressurized solar water heater.
As the water circulates in vacuum tubes, so this kind solar collector is not suitable for cold area. For cold area, we recommend Split  Vacuum Tubes Heat Pipe Solar Collector (BYF58) to assemble large project.
