Hidropneumatic tanks » without membrane » steel

We have in the extractive segment the know-how for the devise, design and manufacture of hydropneumatic steel tanks without membrane for protection against watter hammer blow.
Vast experience, skilled workers and knowledge acquired over more than 30 years guarantee us the competence to manufacture and operate in various business areas.

From the chemical industry to the food industry, through the extractive industry, we also have the capacity to design and manufacture customized solutions.
With a portfolio of standard products and the ability to manufacture custom solutions, we are the right choice for anyone who wants welded constructions of high quality and proven effectiveness.
We are a company with eyes on the world. We do not work for today, we build relations for tomorrow for what we increasingly bet on exporting, producing and shipping to any part, be it national or international territory.
