SLE- Solar system with DUROGLASS boiler and fullplate selective collector

Technical characteristics of boiler:

• Material :cold rolled steel (ST12-30/VE DCP), according to ΕΝ 10130, 3 mm thickness.
• Thickness of exchanger (Jacket) 1,5mm
• Anticorrosion Protection:
  • Internal glass (enamel): liquid glass enamel, 400micron thickness, DIRECT type, according to DIN 4753/T3. The tank is enameled at 860°^.C. Without chemical additives, for absolutely healthy water. No growth of bacteria/microorganisms is allowed. Excellent resistance to time.
  • Magnesium anode
• Test pressure 16bar.
• Working pressure: 8 bar.
• External coat: galvanised steel that is electrostatic painted with polyester powder RAL 9006, with UV protection. (optional INOX 304)
• 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: Φ140
• Electric resistance: 4kW with inox flange.
• Safety valve: 10bar
• Thermostat: Adjustable thermostat (30-90^οC ) triple contact and thermal safety in accordance with Directive 73/23 and 93/68EU.
• 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
