AQUA Blue E2 - Two stage freshwater generator
Alfa Laval AQUA Blue freshwater generators turn seawater into high-quality fresh water through a streamlined process in a single plate pack. The AQUA Blue E2 takes this further with 3-in-1 AQUA plate technology in two stages, reducing its footprint while boosting environmental benefits. It uses 50% less electrical power than conventional single- and two-stage generators and delivers 20–100 m³ of fresh water every day.
Energy-saving AQUA Blue benefits, multiplied by two stages
- Twice the fresh water for a certain amount of waste heat – or the same amount using around half the waste heat
- Retained production of fresh water on vessels that need to slow steam
- Possibility to divert saved waste heat to the E-PowerPack (for generating electricity) or other heat consumers
- Easy maintenance on board thanks to non-glued gaskets
- 50% less electrical power consumption than conventional freshwater generators
Twice the power - same smart design:
The AQUA Blue E2 builds on the proven strengths of the single-stage AQUA Blue E1, including AQUA plates with non-glued gaskets. With two stages, it delivers twice the fresh water for the same waste heat—or the same output using about half the waste heat. That means real support for shipowners on their decarbonization journey.
Need more fresh water? The AQUA Blue E2 can handle it. Need to maintain capacity while slow steaming to meet CII or EEXI targets? It’s ready. And if your vessel has the Alfa Laval E-PowerPack, the waste heat you save can even generate electricity.
A tool for smarter efficiency:
Versatile and energy-saving, the AQUA Blue E2 helps improve your vessel’s Energy Efficiency Design Index (EEDI). To unlock its full potential, connect with Alfa Laval during the design phase.
Why AQUA Blue E2 sets a new standard in freshwater generation
High-quality fresh water – the energy-efficient way
AQUA Blue freshwater generators are the energy-efficient choice for producing high-quality fresh water on board. The single-stage AQUA Blue E1 cuts seawater needs and power consumption in half compared to alternative freshwater generation technologies, and the advantages are multiplied in the two stages of the AQUA Blue E2. With a minimum footprint the AQUA Blue E2 creates numerous possibilities for saving energy and meeting other sustainability goals

Why include two-stage freshwater generators in vessel specifications?
As the marine industry decarbonizes, more systems are competing for the finite or shrinking amount of waste heat on board. Many vessels already struggle to produce enough fresh water with limited waste heat. Others face uncertain capacity needs tomorrow, or they want to leave more heat for other energy-saving opportunities.
Two-stage freshwater generators can address all these concerns. Yet single-stage freshwater generators are the norm in vessel specifications. Download our white paper for concrete comparisons showing the value of two-stage freshwater generation – and the way 3-in-1 AQUA plate technology can multiply it.
Listen to our experts!
Aqua Blue E2 has doubled down on our 3-in-1 technology to achieve twice the capacity with half the waste heat use. Now listen to our expert, Joseph Olsson, explaining the core technology and real savings for your future high efficiency freshwater generation.
