LBF2800F Watermaker

The Spectra LBF2800F Watermaker is a powerful reverse osmosis (RO) water purification unit (ROWPU) with dual stage prefiltration designed to desalinate brackish or fresh water sources while also removing or reducing select chemical contaminants from brackish, seawater or fresh water sources. Available in 24V DC 48VDC, 120VAC and 240VAC.

These units are built using Spectra's revoluntionary Pearson high pressure pump which uses just a fraction of the energy of conventional plants. Features include an enclosed fan cooled motor for long service life, microprocessor based controller with keypad display to monitor and control all functions, integral tank and pump for automatic freshwater flushing of the mem-branes and rugged 304 stainless steel welded frame.

How does the LB2800F work?

Using the included submersible pump, water is drawn from the source and automatically supplied to the main water treatment system. 20 micron and 5 micron pre-filters remove large particulate before final treatment by reverse osmosis membranes. These units are built using Spectra’s revolutionary and proprietary new Pearson high pressure pump. The plants are supplied with a rugged stainless steel frame, Pearson Pump coupled to Spectra’s proprietary Spectraflux™ membrane assembly, micro-processor control system with Burkert prod-uct water diversion valve, pre-filtration sys-tem, automated freshwater flushing system and a motor speed control for total system command. Touchpad display and controls are mounted in sealed enclosure.

  • The most energy efficient desalination system of its size
  • One touch operation will start the system, after which it takes care of itself
  • Low current requirement allows for operation from renewable power sources, inverters, etc.
  • Automatic back flushing keeps system properly maintained and operational
  • Pearson Pump integrated with Spectra’s exclusive oil filtration system for extended service periods
  • Microprocessor based controller with keypad display to monitor and control all functions. Readouts include digital based flow and pressure as well as filter condition and operational hours. A conductivity controller monitors product water quality and automatically rejects poor product water on startup. Tank switches can be integrated to automatically start and stop the system
  • Three way valves and service ports integrated into the system for ease of maintenance
  • 20 and 5 micron Spinring™ Industrial prefilter set protects the membranes.
  • Spectra engineered pressure vessels with proprietary Spectraflux ™ membranes
  • Totally enclosed fan cooled motors for long service life
  • Rugged 304 Stainless steel welded frame
  • Integral tank and pump for automatic freshwater flushing of the membranes is included
