Engine manufacturer's approval for Chemical Free Water Treatment

One of the most critical parameters for maritime engine efficiency and life time is internal corrosion. This is why engine manufacturers provide very clear specifications on the water to be used for cooling.
The instant water enters the cooling system, it causes corrosion, scaling, bacterial contamination and fouling. This has a significant impact on energy consumption, motor components and overall Life Cycle Cost (LCC).

The EnwaMatic Maritime water treatment unit combines reproducible principles of water chemistry with standard water treatment technologies. As per Enwa, the unit provides effective dirt and air separation with environmentally sound water conditioning. It is said to create changes in key water parameters, such as pH, alkalinity and hardness, to elicit corrosion inhibition, control of scale formation and a biocidal effect.

The recent approval of the EnwaMatic water treatment system was preceeded by several years approval period with the final test running for 16,378 engine hours. For this reason, the EnwaMatic was installed onboard the cruise ferry "Color Fantasy", sailing between Oslo in Norway and Kiel in Germany.
