Introduction

Hydromars is a Swedish deep-tech company, founded in 2020, dedicated to advancing sustainable human habitation in space through innovative water purification and recovery technology. 

The core technology is the outcome of extensive R&D that has been rigorously tested both locally and internationally. Full-scale demonstration units have achieved exceptional water quality results across various industrial sectors, including microelectronics manufacturing environments.

Hydromars designs and refines its core components in-house, collaborating closely with its sister company, Xzero AB.
