About the AQUA Blue E2 System
The AQUA Blue E2 utilises a two-stage desalination process designed to maximise water production while reducing energy demand and space requirements. Its innovative plate technology eliminates the need for large shell-and-tube heat exchangers, cutting down both footprint and maintenance.
The result is a compact, highly efficient, and environmentally responsible freshwater generator, built for the demanding conditions of shipping, offshore platforms, and industrial energy operations.
AQUA Blue E2
Engineered to convert seawater into high-quality freshwater. Outstanding performance across marine, offshore, and industrial operations, with efficient operation and low-maintenance reliability.
- Type: Two-stage plate-based freshwater generator
- Function: Converts seawater into fresh water through vacuum evaporation and condensation
- Application: Marine vessels (main and auxiliary engines), offshore platforms, and other installations needing onboard potable or technical freshwater
- Two-Stage Design (E2): Higher efficiency than single-stage systems, reducing energy consumption
- Heating Source: Jacket water, steam, or hot water (using engine waste heat)
- Plates Instead of Tubes: AQUA plate technology reduces scaling and fouling, compact size
- Control System: Fully automated PLC-based operation with monitoring and alarms
- Compact & Modular: Skid-mounted system for easy installation and integration
- Capacity: ~20–100 m³/day (depending on model, seawater temp, and heating source)
- Energy Efficiency: Up to 60% less energy consumption compared to conventional shell-and-tube freshwater generators
- Operating Temp: Works with jacket water as low as ~60°C
- Salinity: Delivers fresh water <2 ppm TDS (potable quality)
- Freshwater pumps and mineralisation units (for drinking water)
- UV steriliser or chlorine dosing units (potability assurance)
- Remote monitoring and automation integration
- Energy recovery options (using dual-stage evaporation)
- High efficiency & low energy use thanks to AQUA plate technology
- Compact & lightweight – ~50% smaller footprint than tube-type generators
- Low operating costs – reduced scaling, easy maintenance
- Reliable, automatic operation with minimal crew involvement
Key Benefits of the AQUA Blue E2 System
- Easy maintenance on board thanks to non-glued gaskets
- 50% less electrical power consumption than conventional freshwater generators
- Compact and lightweight design, reducing space and weight requirements on board
- 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
Aqua Blue: A New Chapter of Energy Efficiency
AQUA Blue freshwater generators provide efficient, high-quality water production at sea. The E1 cuts seawater use and energy consumption by 50%, while the dual-stage E2 delivers even greater savings, helping operators reduce costs and meet sustainability goals.
