  Mannvit   Valendis


In 2009, GTN LA was founded as a daughter company in Santiago de Chile where it services the rapidly growing Latin American geothermal market.


GTN holds 8 % of the shares in this GmbH. Thus, GTN made a clear commitment to geothermal energy use in Germany very early – in 1993 – already.


We use the synergies emerging from this partnership for the development of shallow and deep geothermal energy uses.


Since the foundation of valendis GmbH , high-quality natural consmetics have been manufactured from the thermal brine produced from a depth of 1500 m at the site of Waren (Müritz) and marketed.
