Continuous deaeration also available for solar systems
Extremely high temperatures can occur in solar systems, which leads to the formation of steam. Valves are installed to prevent vapour release and overheating. Without valves, solar systems can even boil 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.

We feel that being honest is a much better policy to win your trust rather than trying to lure you with nearly impossible statements such as life time warranty. Nothing lasts forever! Our warranty policy is simple; we offer a 3 year warranty on everything we sell and 10 years on our collectors. With this warranty you will get NO hassle next business day replacement (if shipping service and inventory permits). However, as a valued customer you will get technical support through the life time ownership of your product. Our Collector do carry longer warranties 10 years from the manufacture. The warranty cover failures that occur durring normal operational conditions or manufactures defects. It does not cover failure due to inapproptiate operation such as freezing or over heat. Damage caused by vandalism, storms, floods etc. Your houshold insurance should be modified to cover the system from such situations.
