Our ambition is clear: to become a key global player in water treatment.”

Osmosun® (formerly Mascara NT): the world’s only industrial solution for solar-powered desalination of seawater and brackish water

Based in Gellainville (Eure-et-Loir), Osmosun® specializes in innovative water treatment solutions using renewable energies. Founded by Marc Vergnet and managed by Quentin Ragetly, the company designs, manufactures and markets the world’s only industrial seawater and brackish water desalination solution that can be powered autonomously by solar energy (or hybrid with the local electricity grid). Daily production capacity ranges from 1 to 50,000 m3.

Its major innovation, patented in 2015, is based on its know-how in the intelligent management of available electrical power (variable with ENR) to provide stable power to the membranes that enable reverse osmosis (to fix the salt and make the water drinkable) and thus avoid damaging them.

Gaia has been supporting the company as a board member and shareholder since 2019.

A market driven by global tensions in the water and energy sectors

With customers increasingly looking for decentralized, low-carbon desalination solutions that also enable them to control brine discharges into the environment, Osmosun® is stepping up its development and multiplying its references: 50 small-capacity plants, 1 medium-capacity plant (45 m3/h) for the mining sector in New Caledonia, and 1 large-capacity plant recently won in Mauritania (2 x 105 m3/h).

To keep pace with this growth, the company has increased its production area to over 2,000 m² and has embarked on an ambitious industrialization plan, enabling it to achieve an annual capacity of 4 to 5 high-capacity units and 20 low-capacity units. Since its inception, the company has produced over 2 million cubic meters of drinking water via its desalination units.

The IPO will enable Osmosun® to ramp up production resources, set up sales offices in 4 priority zones (Middle East, Africa, Asia-Pacific, Latin America), strengthen its network of partners (civil engineering, maintenance, etc.), carry out build-ups to accelerate growth, secure key components where there is only one strategic supplier and position itself in the related recycling market (reuse of wastewater, etc.).

The global placement, mainly aimed at institutional investors, and the open price offer, mainly aimed at individuals, were met with great success, illustrating investors’ confidence in OSMOSUN’s positioning, development strategy and growth prospects.
