SASAKURA 25-ton/day Marine Vacuum Flash Evaporator: Advanced Seawater Desalination Solution
SASAKURA proudly presents the ZFS (HDZF) series Marine Vacuum Flash Evaporator, a cutting-edge line of tubular distillation-type seawater desalination devices. These innovative devices harness low-grade waste heat, such as that from diesel engine cylinder cooling water, as their primary heat source. Employing the principle of vacuum cryogenic distillation, the system effectively boils seawater under reduced pressure to produce high-quality freshwater. With a compact structure, reliable operation, easy maintenance, and a high degree of automation, the ZFS series ensures finished water with exceptionally low salt content (below 10mg/l), meeting the stringent requirements for potable water.
The ZFS (HDZF) series seawater desalination devices are designed to comply with GB5749 “Sanitary Standards for Drinking Water,” ensuring the production of safe and clean water for various applications. These devices have been extensively utilized in ships, fishing boats, workboats, and islands, providing a reliable solution for freshwater needs in marine environments.

Principles:
The ZFS series operates by heating seawater using waste heat, causing it to vaporize through boiling distillation. The seawater undergoes a process of heat vaporization, separation, and condensation to transform into freshwater. The bottom heater of the device circulates hot water, transferring heat to the seawater passing through the straight heater. As the seawater is heated, it evaporates and boils, with the vapor rising and the remaining concentrated brine being discharged by a vacuum pump. The vapor is separated into a condensing cavity by a separator, where it condenses into distilled water through heat exchange with cooling water pumped through the system. Non-condensable gases are extracted by the vacuum pump, maintaining a high vacuum within the device for efficient operation.
