Dri Boss DBE750

The DriBoss DBE-750 Evaporator is a floating unit that uses water fracturing technology to create optimum water droplet distribution for evaporation.


  • FLOATING UNIT supported by plastic pontoons containing closed-cell PU foam.
  • LOW PLUME HEIGHT for shorter drift distance, allowing longer operation in swirling or changing winds
  • HEAVY INDUSTRIAL CONSTRUCTION, including stainless control panel, motor enclosure, manifold and fan blade for increased durability and lifespan.
  • VIBRATION SENSOR included to shut down motor before catastrophic failure due to residue or ice build-up.
  • STAINLESS STEEL SUBMERSIBLE PUMP attached to floating frame.


  • LOW BUILDUP: The DBE-750 Evaporator is designed with a minimal amount of top surface area to control the build-up of residue or ice, helping to reduce clean up and maintenance.
  • HIGH PERFORMANCE: High-speed fan blade rotation creates an optimum water droplet distribution for evaporation. Annual evaporation rates up to 70% have been achieved, with average rates typically between 25 and 60%. Evaporation rates depend upon many factors, including ambient temperature, relative humidity, water makeup and wind.
  • EASY MAINTENANCE: This unit is designed for easy cleaning and maintenance. It requires no weekly bearing lubrication, as it is lubricated for the life of the motor.
  • MINIMAL CLOGGING: The DBE-750 Evaporator can pass particles up to 3/16 inch (4.7 mm) in diameter, which reduces the need for pre-filtering, filter cleaning and the hassles of clogged nozzles.
  • EXTREME DUTY: This design has evolved from 10 years of experience in industrial and extreme outdoor applications. Polyethylene pontoons are filled with closed-cell polyurethane foam, ensuring bouyancy even after any accidental puncturing of the plastic outer shell. Critical components are manufactured from stainless steel for extended life in harsh environments.
  • specifications


  • 25 HP industrial-grade world motor for 3-phase / 480 volt / 60 cycle and 3-phase / 400 volt / 50 cycle power (motors for other voltages available upon request).
  • Stainless steel casing protects motor and enhances cooling.
  • Patented stainless steel fan blades (optional scale-resistant coating).
  • Vibration sensor for motor shut off.

  • Optional high flow, stainless steel water manifold for above average evaporation conditions. Designed for flow rate of 91 gpm (344 lpm) at 100 psi (7 bar) water pressure.
  • Y-line manual flush filter for dirtier water.

    why evaporate?

    Evaporation is considered as an alternative process to a number of wastewater treatment applications, such as reverse osmosis, chemical dosing or desalination. The evaporation process may be carried out naturally in solar evaporation ponds (which is slow and requires a great deal of area) or by mechanical evaporation. Natural solar evaporation is often limited by land availability and the cost of constructing additional storage ponds, not to mention the added cost of clean-up and re-vegetation. Evaporation machines can significantly enhance the evaporation process, with up to 14 times more efficiency than pond evaporation. DriBoss® evaporation machines are relatively compact, reliable and efficient and can be transported to different sites as necessary. They can be a low-cost addition to improve evaporation rates and volumes on existing containment ponds or to minimize new pond surface area.
