Pressure thermosyphon systems

  • Boiler with increased thermal insulation with a thickness of 80 mm.
  • CS selective flat collector with aluminum absorber coated with PVD high quality selective coating.
  • Triple ultrasonic welding – a unique and innovative technology allowing high efficiency, long-term stability of the collector.
  • Heat-tempered, prismatic, transmitting maximum amount of solar radiation, anti-reflective glass.
  • Non-freezing heat transfer fluid / propylene glycol / between the collector and the coil of the boiler.

Vacuum tube collectors

The vacuum tube collector is created with new U-type vacuum tubes.

The tube collector consists of 10 or 15 vacuum-insulated glass tubes with high efficiency, selective coating on the inside of the tubes, which improves absorption and insulation.
The vacuum further increases the efficiency of heat storage. The absorber is constructed using patented U-type copper tubes that are ultrasonically welded.
From the U-tubes, the heat is collected in a collector, which is placed in a box made of anodized aluminum and insulated with high-density stone wool.

Combining the latest research and technology, these are some of the most efficient collectors on the market today and have received Solar Keymark certification.

Flat selective collectors

The collector absorber is made of aluminum sheet on which a high quality selective PVD coating is applied by physical vapor deposition.

Triple ultrasonic welding is used to attach an aluminum sheet to the grid of copper pipes through which the fluid flows – a unique and innovative technology allowing high efficiency, long-term stability and good design of the collector.

The collector box is made of aluminum and is insulated with high-density stone wool, which guarantees minimal heat loss in the most extreme conditions.

The glass is solar thermally tempered (with low iron content), prismatic, transmitting the maximum amount of solar radiation, with anti-dust and anti-corrosion coating. This allows it to retain its original optical characteristics for a long time.

The sealing between the housing and the glass is done with the help of heat-resistant silicone, for minimal heat loss and elegant finish.
