All well-known benefits of the NAU high-performance collectors have been extended to an optimal 2.54m² format. More area – more collector output.

Extra flat design:
With the NAU SLIMLINE we have managed to develop a super-flat collector with a structure of only 72 mm through a highly efficient back wall insulation. 

New design:
The new shaped aluminium frame profile is not only distinguished through its superior quality, it also gives the NAU SLIMLINE a more elegant optical appearance.

• New collector size 2.54 m²  
• Extra flat style – new design
• Optical efficiency approx. 0.8
• Larger collector area = more governmental support
• Well-known qualitative high-class processing technique
