In spring 2012, specTra took a stake in triple S-GmbH, which was founded in 2008, and supported the growth of the aspiring company with appropriate funds.

triple S has developed a geothermal-based and patented heating system for switches in the rail network and for surface heating, for example for platforms.

The company already received approval for the rail network of Deutsche Bahn AG in 2011 and had its development patented.

International customers from the rail infrastructure sector and industrial customers are increasingly relying on more efficient and effective point heating systems that meet the ecological requirements of the future.

Here the triple S is a pioneer and clear innovator in the field of sustainable and green geothermal technology.

Heat sources from deep boreholes, industrial wastewater, near-surface waters, etc. are used.

In the difficult market environment of the project business with customers such as Deutsche Bahn, triple S needed fresh equity.

SpecTra and other shareholders sold their shares to a private investor in 2016 in order to ensure further growth.
