Triple-Layer Tanks maintain the temperature and purity of the water inside them with an innovative external solid-skin layer to protect the fluid inside the tanks from shocks and UV light. The tanks’ second layer, made of polyethylene foam, provides thermal insulation and adds strength to the tanks. The internal layer is free from colorants. Triple-Layer Tanks are German DIN certified by MFPA Weimar in Germany (The German Official Testing Center), as being harmless for the storage of drinking water and food.
