The key role in the process of solar energy acquisition belongs to the solar collectors. They bind solar radiation (solar energy) and convert it into valuable heat (thermal energy). In place of the hose, the collector has an aluminum absorbent material. This binds the solar energy, heats and transfers the heat to the water passing through copper pipes, which rest on the absorbing. The special coating and the very efficient insulation ensure that as little solar heat as possible is lost. So simple and so effective!
The solar collector energy efficiency ANDRIANOS reaches percentages up to 69%, which are among the highest efficient in the world, top 5. In addition, exceptional insulations ensure low heat losses. Therefore offers its customers one of the highest quality and most competitive solar collector solutions in Europe.
