solar flame OLC

Solar Flame OLC

Model OLC200 is a flat plate collector encasing harp type absorber with high efficiency. It is a great and affordable choice, best suited for open loop / natural circulation systems, making OLC200 a good choice especially for hotter climates and harder waters. The efficiency factor of OLC200 is η0=0.68 (based on gross area). This collector has been tested in NSCR DEMOKRITOS laboratory in Greece and is certified with SOLAR KEYMARK.

 Description:

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.
