Oasis-3 Multiple Power Options

Our Oasis-3 water purification system is currently being developed. We expect to launch the product by Q2 2017. Please join our mailing list for updates including pricing and availability. Thank you.

The Oasis-3 Water Purification System is designed to be as robust and flexible as possible.

One of the things we made sure about is that our portable drinking water purifier unit will work with multiple power options no matter where you are in the world.

Our Design Goals

  1. Must be powered from 11-36V DC
  2. Must be powered from 85-265V AC 50/60 Hz
  3. Must be powered from a solar panel
  4. Solar panels must be shipped with the unit
  5. Unit must include a rechargeable battery
  6. Battery must be "airline friendly"
  7. Battery must be recharged from any connected power source
  8. Unit must allow other batteries to be recharged using the built-in chargers
  9. Unit must allow cell phones and other electronics to be powered
  10. Control panel must be uncluttered, and simple to understand and use
  11. Unit must be simple to repair in the field

Oasis-3 Power Features

Rechargeable Battery

The battery we chose is a high quality, compact, deep-cycle battery with a number of important features suited to the task of a portable water purification unit.

  • Battery can be charged from solar panel or 110-240V AC power
  • Flat and thin, 99.99% pure virgin lead (not a lead alloy) plates provide greater surface area to store power
  • Can handle 400 charge-discharge cycles to 80% depth of discharge
  • 27 minutes reserve capacity
  • Drycell (“starved electrolyte”) means no external leakage or corrosion
  • Can withstand extreme vibration
  • Can be installed in any orientation
  • 8-12 year design life and 3-10 year service life (3 times longer than conventional batteries)
  • Can be stored for up to 2 years and still be returned to full power
  • Loses power slowly towards end of life, meaning no sudden or catastrophic failure
  • Air transportable; US Department of Transportation classifies these as "non-spillable", therefore less expensive to ship
  • Battery ships fully charged and ready to go
  • USA designed and made

Compared to conventional batteries (show on the right), our battery uses flat plates of pure lead (show on the left) which stores more power and reduces overall space by 15%. Because our battery has no free acid inside, it is covered under the US Department of Transportation unregulated "wet nonspillable wet electric storage batteries" classification and International Air Transport Association (IATA) "unrestricted" air shipments categories. These batteries may be shipped completely worry-free.
