Flat plate aluminium collectors PremiumPlus AL

Peak performance for single houses as well as for large plants ...

The aluminum flat-plate collector with its TiNOx Energy coated full aluminum absorber and thick-walled turbo pipes hast a gross collector surface of 2,86m² and a powerful heat transfer rate. It is perfectly suitable for DHW heating, backup heating and the generation of process heat. Up to 15 panels can be connected in series and it is available in vertical (V) and horizontal (H) design.

The Solarbayer high performance flat plate collector PremiumPlus AL is one of the most efficient collectors that is on the market at the moment. This collector type is characterized by its design and its powerful performance. Due to its special absorber properties you will gain a maximum of heat. It is first choice to realize larger collector arrays in an easy to install way. Solar systems by Solarbayer, including high performance collectors and system components, cover up to 70% of the annual average of the energy consumption for heating up domestic hot water. There is even enough solar power to almost cover the complete need of energy to heat up drinking water during the summer months. Our high performance collectors are particularly designed for the application in backup heating systems. Therefore, the expenses for oil and gas, for example, are distinctly reduced and you will be half-way independent of fossil fuels. The special installation technique even enables the installation in higher snow load zones when an appropriate substructure is provided.

As a further development of the high quality collector PremiumPlus Solarbayer has launched the flat plate collector PremiumPlus AL to enlarge the product range. It is the „Full-Alu-Alu-Absorber“ that is the „new“ and special specification of this collector. An aluminum absorber plate with high selective coating that is connected to a thick-walled aluminum pipe by the aid of an especially developed welding method. The approved aluminum casing is the same as with the popular copper flat plate collector PremiumPlus, which is, of course, still going to be manufactured. Thus, no reorientation is necessary for the installer when mounting this collector. Due to the characteristics of aluminum more material can be applied in an aluminum collector than in a collector with copper absorber, since the weight of the aluminum collector is way lighter. Solarbayer applies special turbo pipes as absorber pipes with internally corrugated surface. The thus resulting enlargement of the heat exchanger surface clearly increases the heat transfer rate and the collector performance will be increased up to 5%!

Take advantage of these benefits

  • high selectively coated aluminum absorber
  • internally corrugates aluminum absorber pipes in special Solarbayer meander form (serpentine absorber)
  • powerful heat transfer rate
  • high corrosion-resistance
  • little weight, easier to transport
  • high surface quality
  • manufactured ecologically and low in CO2 emission
  • highly diaphanous solar safety glass for even more energy yield
  • high quality, gas emission free rock wool (50 mm)
  • solid aluminum double profile frame, anodized black
  • weather and UV-resistant materials
  • flexible stainless steel collector connection for compensating the thermal expansion

This has to be paid attention to when installing the aluminum collector PremiumPlus AL:

  • All connector connections and couplings within the collector array, also in the roof penetration, imperatively have to be made out of aluminum or stainless steel Only use our PremiumPlus AL connection accessories
  • We recommend our solarpipe stainless steel corrugated hoses for the rising pipe as supply pipe for the collector array. Additional advantages of this solarpipe are the easy installation and the already integrated sensor cable, as well as the high temperature resistant insulation of the flow and return line.
  • No risk of corrosion! No risk of corrosion exists within the solar circuit when the original Solarbayer long-life solar fluid is used. Hence, an extremely high heat transmission is achieved as well as an enormous system persistence.
