Product range

Specialist solutions require high customer focus

Our diverse and dedicated team of engineers is developing, manufacturing and distributing freshwater solutions for and to customers worldwide. Thanks to a creative out-of-the-box mindset, this team excels in innovative and specialist solutions, bespoke set-ups that require a high customer focus.

Every successful implementation of a freshwater generator starts with an accurate analysis of the vessel's status, identifying possibilities and needs. In each case our team will strive for a solution that is most energy and space efficient. A higher energy efficiency, for instance, can often be reached by looping to energy sources already available on a vessel. Greater flexibility in construction and sizing can be accomplished by making a combination of different FWG technologies. This approach especially comes in handy when retrofitting engine rooms.

Over 125 years of experience in designing, manufacturing & servicing freshwater generators for the marine industry

The company’s expertise in freshwater generation is unrivalled: in 1894 Serck Como started producing its first evaporator for sea-going vessels. Having survived two world wars, we know what it means to adapt to ever changing circumstances. We believe that it is important to both invest in own innovations and to adapt to new external trends. As water maker specialist our focus is on the future. We are confident to come up with new solutions for technical challenges that may come our way.
