System design

Our team of design engineers has extensive experience collaborating with naval architects and shipyards to create reliable and cost-effective systems that require minimal maintenance. Our goal is to provide you with an equipment package that precisely meets your requirements.

To continually enhance our products, we maintain strong connections with the yachting industry in the Mediterranean, the Balearics, and worldwide. We actively gather feedback from service engineers and use it to implement continuous improvements.

Refit services

Refit projects require careful planning and often present challenges in terms of space availability. As our work often involves integrated equipment packages that include the installation of reverse osmosis desalinators, freshwater treatment systems, or hot water systems we carry out a thorough survey to determine the precise requirements for each project.

We have substantial experience in designing bespoke solutions for refits. Many of our systems are available in modular form or can be easily adapted, ensuring that the equipment fits comfortably within the available space.
