solar flame OLS series

Solar Flame OLS series

  • Direct heating of consumption water for fast heating

  • Ideal solution for warm climates

  • Certified open loop systems

  • Passivated Inox 316L tank

  • Heavy duty aluminum support structures

  • Easy installation

  1. Water storage tank: Stainless steel vessel made of high-quality stainless steel (INOX316L), passivated for extra corrosion resistance.
  2. Outer cover: 1 layer of primer and 2 layers of powder coating on Aluzinc cold rolled steel sheet. Aluzinc stands for aluminium and zinc, fused in almost equal proportions, as a coating for the steel sheet that is coated with a silvery spangle composed of Aluminum (55%), Zinc (43,4%) and a touch of Silicon (1,6%). Great mechanical strength and 7 times more resistant to corrosion than common galvanized steel.
  3. Thermal insulation: Ecological and incombustible, high-density (>40kg/m³) expanded polyurethane surrounds the water storage tank and jacket for minimum heat loss, maintaining the hot water temperature, thickness 50mm.
  4. Side flange: 1 ¼” threaded opening for safe sealing  
  5. Cathode protection: 1 Magnesium anode rod for extra protection against corrosion and mineral deposits caused by electrolytic reactions.
  6. Heating element: Incoloy, rated according to the destination country’s local regulations (optional, for the use of electricity as an auxiliary power source).
  7. Protective cover: Protection of the electrical part.
  8. Cold Water inlet & outlet to collector: Inox BSP male threaded pipe end 3/4”. At this connection a 7 bar safety non return valve must be placed for pressure relief.
  9. Auxiliary inlet: Inox BSP male threaded pipe end 3/4”. For extra sensor or a pressure and temperature relief valve optionally may fit this end.
  10. Hot Water (DHW) outlet: Inox BSP male threaded pipe end 3/4”.
  11. Inlet from collector: Inox BSP male threaded pipe end 3/4”.
  12. Auxiliary inlet: Inox BSP male threaded pipe end 3/4”. Ideal for recirculation or drain.


  1. Frame of the collector: Aluminium profile powder coated for maximum protection in seaside areas.
  2. Absorbing surface: Aluminium surface with black lacquer selective treatment with high absorption and low emission (α=90%, ε=20%), laser welded on the copper water frame.
  3. Transparent cover: Security-Tempered solar glass for maximum protection against extreme weather conditions and temperature changes.
  4. 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.
  5. Vertical tubes: Copper tubes in diameter Ø12mm.
  6. Thermal insulation: 30mm thick layer of prepressed mineral wool special for solar panels for minimum thermal loss. Thermal conductivity: 0=0.035 W/m°K (EN 13162) and heat capacity 0.84 kJ/kgK.
  7. Back cover: Aluminium sheet 0,4mm thick. Greater resistance 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, silicon air vents and silicon header flanges) resist to extreme weather conditions and temperature changes.

The collector can be installed on a flat roof, tiled roof and in-roof.
