Add to compare
  • The PureFlex DLX PF-DLX-SW-40 is an industrial-grade modular seawater reverse osmosis (RO) desalination system designed for medium-capacity, high-pressure seawater desalination applications.
  • This model provides a nominal production capacity of 4,000 gallons per day (GPD) and is designed for seawater applications (generally up to 40,000 ppm TDS).
  • The system is enclosed within a powder-coated marine-grade aluminum frame and incorporates industrial-grade piping, fiberglass membrane pressure vessels, advanced microprocessor-based controls with touchscreen interface, and a variable frequency drive (VFD) for efficient pump operation.
  • Seawater models utilize Danfoss APP high-pressure pumps constructed of duplex stainless steel.
