solar flame FMAX series

Solar Flame FMAX series

Model FMAX is a superior flat plate collector encasing harp type absorber with very high efficiency level. It is best suited for closed loop /natural or forced circulation systems, small or large scale, great choice for mild and colder climates, where its great insulation properties are desired for minimizing thermal losses and maximizing efficiency. Overall FMAX lies in the top 3 most powerful certified collectors produced in Greece, in terms of annual output (the other 2 are our MTEC-27 and our FMAX-TOP) and one among the best harp type collectors worldwide. This collector has been tested in NSCR DEMOKRITOS laboratory in Greece and is certified with SOLAR KEYMARK and soon with SRCC.

Description:

1. Frame of the collector: Aluminium profile powder coated for maximum protection in seaside areas.

2. Absorbing surface: Aluminium surface with blue titanium high selective treatment with high absorption 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. Header of water frame: Copper tubes Ø22, which are 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 Ø8mm.

6. Thermal insulation: 40mm 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: Aluzinc 0,4mm thick. 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 Aluminium (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.

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 or tiled roof.
