Maritime know-how

Historically, Compagnie Hydrotechnique began by offering water purification solutions for sailors and maritime expeditions. Its expertise quickly developed thanks to an approach focused on innovation and the robustness of its equipment. Today, we distribute and manufacture high-performance desalination systems tailored to the needs of both ocean racing and long-distance cruising.
A complete range for every need
Compagnie Hydrotechnique offers three major brands of watermakers, each meeting specific requirements:
- Katadyn, with the Power Survivor 40, a benchmark in ocean racing. This compact, efficient model is designed for sailors looking for a reliable solution with controlled energy consumption.

- UNITAM, Compagnie Hydrotechnique's own brand, stands out for its simple, rustic models, designed and assembled directly in Bouaye. Suitable for yachtsmen and adventurers looking for sturdiness and ease of maintenance, these units are designed for optimum autonomy at sea.

- BlueWater Desalination, a top-of-the-range American brand, offers solutions such as Legend and Express XT, fitted as original equipment on Lagoon, Nautitech and other catamarans. These models incorporate the latest technological innovations for maximum comfort and optimized freshwater production.


Tailor-made support
Beyond simple distribution, Compagnie Hydrotechnique makes it a point of honor to support its customers in the choice and maintenance of their watermaker. Thanks to a responsive after-sales service and a substantial stock of spare parts, we can guarantee long-lasting, reliable support for all our users.
