Flat plate aluminium collectors PremiumPlus AL
TiNOx Energy absorber coating with thick walled internally corrugated turbo pipes and
very powerful heat transmission rate for highest solar energy yield,
available with 2,86 m² gross surface area, best for all kinds of solar thermal
applications, for example as DHW preparation,
solar heating support or process heat generation

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.
