No valves required, no danger for boiling dry
Thanks to a patented invention, Spirotech can offer a solar product range with the so-called AutoClose function. These valves only close if it is really necessary. The process is completely automatic, so no more climbing onto the roof to deaerate the system. Nor is manual deaeration necessary.
Thanks to the AutoClose principle, solar systems can now be kept permanently deaerated. This improves effi ciency and prevents all manner of inconveniences, symptoms and system wear.
