 Features for direct flow vacuum tube

1. This is Full Vacuum Tube with Direct Flow Pipe.
2. High heat efficiency, 15% higher efficiency than normal vacuum tube. 
3. The direct flow pipe is made up by two concentric single-wall-tubes.
4. Cold water follows through the inner tube from upside down and flows out to the collector from the bottom through the space between the inner & outer tube, taking the heat made by the absorber.
5. It could be installed at any angle, even horizontally, while normally heat pipe tube should be installed at 30°-90°

 Features for direct flow vacuum tube solar collector

The KM-ZL70A series collector module is a kind of direct flow solar collector, which system consists of vacuum tube, inner tube of vacuum tube, manifold and inner manifold. The inner tube is connected with the inner manifold and the vacuum tube. The heat-transfer fluid flows through the inner manifold, inner tube, vacuum tube and manifold in turn. The effective heating position is the space between inner tube and vacuum tube. This system allows any installation angle of the module between 0° and 90° allowing the absorber surface being adjusted to the optimum position towards the sun.

 
Customization and convenience

Direct flow vacuum tube solar collectors apply direct-flow which even increases their efficiency. The heat transfer fluid in the concentric tubes of the absorber transfers the heat. All direct flow collector tubes are connected in parallel. This allows any arrangement of the module at tilt angles between 0° and 90° with the absorber surface adjusted to the optimum angle. Each tube can individually be arranged to the optimum position towards the sun to receive the maximum solar irradiation throughout the year. Due to these characteristics, the collectors can meet special customer demands as integration into facades or horizontal installations on flat roofs.

 
Top performance and versatility
An important asset of direct flow solar collectors is their versatility. One of the application areas for direct flow solar collectors is domestic water heating. Therefore, installation requires remarkably little space making it practically applicable at any domestic place. Despite their little size, the collectors still cover over 70% of the hot water needs of an average household. Their excellent efficiency makes them also suitable for the operation of larger systems for commercial or public use. In addition, direct flow solar collectors are also applicable for space heating and air-conditioning
