Benefits of Seido tube collectors

Highly efficient vacuum tube collectors are the right choice when top performance is in demand - throughout the entire year.

By preventing air circulation (convection), the vacuum provides efficient insulation and simultaneous protection from environmental influences.
This offers constant high efficiency. Their maximum attainable temperature of 250°C, makes tube collectors an excellent option, and desirable to support traditional heating systems.

Our Seido tube collectors come in three different types, optimized for different requirements and applications:

 


>Seido 1

>Seido 2
>Seido 5
