• Hot water output.
• Closed circuit output.
• Cold water inlet (water supply network) with 10 atmosphere safety valve.
• Enameled coil for connection to central heating (only for triple energy boilers).
• Closed circuit safety valve.

COLLECTOR TECHNICAL CHARACTERISTICS

• Aluminum collector frame (powder coated).
• Aluzinc collector back 0.4mm thick.
• Selective absorbing surface high selective PVD coating with absorption coefficient α = 0.95 ± 0.02 and emission coefficient ε = 0.05 ± 0.02.
• Welding with laser technology to optimize performance. Copper hydroskeleton Ø 22mm (headers) and Ø 8mm (risers) for optimal flow of the thermal carrier.
• 30mm thick stone wool insulation and 20mm thick side reinforcements.
• Security safety glass, 4mm thick, for complete tightness, EPDM rubber is placed between the glass and the frame.
