Specification

Technical Specifications

Thermosyphon closed loop solar systems “Solar Flame MAX” with the following benefits:
✓ Large range of versions (49 systems), certified according to SOLAR KEYMARK.
✓ Compact system setup, for easy transport and installation.
✓ Customized design, for exclusive OEM versions.

Tank:
➢ Glass-dual enameled (according to DIN4753, part 3) double walled (with large jacket heat exchanger) boilers, with optimized heat insulation and durable external cover for maximum protection in seaside areas.

The collectors:
Superb efficiency rating collectors “Solar Flame FMAX” (η0,a=83% according to EN12975 Standard) series with:
➢ High selective PVD absorber coating, for fast and high temperature production.
➢ Water frame entirely made of copper.
➢ Tempered Hail-resistant solar low iron glass.
➢ Maximum heat transfer between the absorber sheet and the copper water frame, thanks to optimized laser welding technology.
➢ Incident angle modifier Kθ =0.96 at 50° ensures maximum radiation absorption throughout the day.
➢ High quality, recyclable materials ensure a long service life and high environmental compatibility.

The support structures:
➢ Support structures with high endurance and easy installation on flat or inclined tiled surfaces.
➢ Easy and safe installation due to special high quality and reliable accessories included in the connections’ kit.

Thermal Solar Collector :

Overall Dimensions : 1980 x 1010 x 86 mm

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

Absorber surface : Aluminium surface with blue titanium high selective treatment with absorbence and low emission (Alpha = 95%, beta = 4%), laser welded on the copper water frame.

Transparent Cover : Security-Tempered prismatic solar glass for maximum protection against extreme weather conditions and temperature changes.

Header of water frame : Copper tubes dia 22mm, 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.

Thermal insulation : 40mm thock layer of prepressed black mineral wool special for solar panels for minimum thermal loss. Rockwool insulation thermal conductivity : 0=0.035 W/m oK (EN13162) and heat capacity 0.84 kJ/kgK.

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 resisted to corrosion than common galvanized steel.

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.
