On request
Tax included

The Thermosiphon system is composed of flat solar panels and water tanks that are located on top of the panels.

Intended for single-family homes, thermosiphon solar systems are ideal for small spaces and the appropriate solution for a quick, easy and economical installation of water heating and are designed to provide high performance, durability, ease of installation and maintenance, both on flat as well as sloping roofs.

  1. Frame of the collector: Aluminium profile powder coated for maximum protection in seaside areas.
  2. Absorbing surface:  Aluminum surface with blue titanium high selective treatment with high absorbance and low emission (α=95%, ε=4%), laser welded on the copper water frame.
  3. Transparent cover: Security-Tempered prismatic solar glass for maximum protection against extreme weather conditions and temperature changes.
  4. Vertical tubes: Copper tubes in diameter Ø8mm.
  5. Header of water frame: Copper tubes Ø22, which is welded to the vertical tubes with hard silver solder. Each water frame is tested at the pressure of 15 bars. Headers are punched with upper expansion for perfect fitting with vertical tubes and minimum pressure drop in the collector.
  6. Thermal insulation: 40mm thick layer of prepressed black mineral wool special for solar panels for minimum thermal loss. Rockwool insulation thermal conductivity: 0=0.035 W/m°K (EN 13162) and heat capacity 0.84 kJ/kgK.
  7. Back cover: Aluzinc 0,4mm thick. Aluzinc stands for aluminum and zinc… fused in almost equal proportions, as a coating for the steel sheet that is coated with a silvery spangle composed of Aluminium (55%), Zinc (43,4%) and a touch of Silicon (1,6%). Great mechanical strength and 7 times more resisted to corrosion than common galvanized steel.
  8. Sealing materials: For perfect waterproof finish and proper ventilation of collectors casing, all materials used (EPDM, polyurethane sealant) resist to extreme weather conditions and temperature changes.
