Each year GREENoneTEC uses approximately 3,500 tonnes of copper and aluminium for the production of different absorber types. A seamless supply chain and the continuous optimisation of our production methods provide a decisive competitive advantage.

The automation of the semi-finished materials production in combination with a consistent quality assurance system plays a key role. For example, an automatic pipe-binding plant which virtually eliminates radial burrs at the pipe is used at GREENoneTEC to make collector lines with a diameter between 18 mm and 22 mm.

Automatic brazing stations are used to braze meander and staged pipes of the GREENoneTEC standard absorbers at 700 °C. The method uses natural gas and allows the application of optimised standard brazing parameters.
