SLI-Solar system with INOX tank and fullplate selective collector

Technical characteristics of boiler:

• Material: : totally made of INOX 316-L
• Thickness of exchanger (Jacket) 1,5mm.
• Test pressure: 16bar.
• Working pressure: 8 bar.
• Insulation: ecological polyurethane (without CFC), 50mm thickness, 40kg/m³.Heat transfer coefficient 0.019 kcal/m/h/^οC^.which keeps the water hot.
• Inspection Flange: Ø140mm,
• Electric resistance:: 4kW with inox flange for hot water even in cold days without sun.
• Safety valve: 10bar
• Thermostat: Adjustable thermostat (30-90^οC ) triple contact and thermal safety in accordance with Directive 73/23 and 93/68EU.
• Anticorrosion Protection: magnesium anode
• Possibility of connection to the central heating system, with the addition of an optional spiral exchanger (serpentine).

Technical characteristics of collectors:

• • Absorber material: aluminum, PVD technology, blue selective fullplate.
  • Absorber type: HARP
  • Absorber welding: Laser
  • Riser: Φ8mm.
  • Frame: A punching method used to form a sturdy totality between the frame and the glass. Also in order to prevent corrosion ALUZINGtechnology is used.
  • Sealing: rubber mastic (silicone) type EPDM of high thermal resistance, resistant to ultraviolet radiation
  • Glass: tempered (safety) according to DIN 52337 Mislite 4mm
  • Insulation: glasswool 40mm,20kg/m³
  • Header: 2 or 4 Cu Φ22
  • Absorption : α=95% (±2%)
  • Transmission: ε=5% (±2%).
  • Antifreeze liquid. Antifreeze fluid S-H-Fluid (non-toxic propylene glycol -14 to +170^οC). It also does not allow salts to be deposited on the collector.
