Easy cleaning process of the Hydroniq Pleat Cooler

Reduce cleaning time by more than 90%.

With the Hydroniq Pleat Cooler we have solved the main challenge of seawater cooling - the cleaning process. Through smart design and greatly reduced number of components the process is easy and efficient. This ensures the vessel's uptime and problem-free working days for the crew. Pleat is a patented solution.

Sealed at first attempt!

A part of the hassle-free cleaning routines is the easy reassembly. The Hydroniq Pleat Cooler is designed with only one gasket between elements, and mechanical stops when reassembling the cooler.

A fraction of spare parts consumption.

A natural consequence of well-thought-out design is fewer and more robust parts in use. By folding the titanium sheets we dramatically reduce the number of gaskets used in the Pleat technology, and thereby reduce maintenance time and cost. By making things simple, we can also increase the intervals between each maintenance.


We have delivered heat exchange systems to a wide range of customers and projects over a long time. Below you will find a list of recent installations.
