Tecnicomar Oasis Watermaker

Tecnicomar OASI Low-Energy Watermaker

The Tecnicomar OASI Watermaker is designed for vessels where electrical consumption is a key constraint. Rather than relying on a conventional high-power arrangement, OASI uses a low-pressure pump and hydraulic pressure multiplier to generate the pressure required for reverse osmosis.

Key Features & Technical Information

• Modular reverse-osmosis watermaker for sailing and motor boats
• OASI 30: 35 L/h, 840 L/day (220 GPD), 0.2 kW
• OASI 60: 60 L/h, 1,440 L/day (379 GPD), 0.55 kW
• 12/24 V DC operation
• Manufacturer states energy savings up to 80% compared with traditional plants
• Can be powered from battery systems connected to wind or photovoltaic generation
• Low-pressure pump raises feed water to around 15 bar before hydraulic pressure multiplication
• Carbon-fibre pressure vessels
• FDA-compliant membranes and filters stated by Tecnicomar
• Optional automatic membrane flushing, control panel, remote control and activated-carbon filter

Models, Capacity & Selection

Current models are OASI 30 and OASI 60. Manufacturer current-draw data is 14 A at 12 V / 8 A at 24 V for OASI 30 and 38 A at 12 V / 20 A at 24 V for OASI 60.

Why This Matters Onboard

OASI is particularly relevant to sailing yachts, expedition-style cruising boats and other vessels that want to make water without running a large AC generator solely for the desalination plant.

Frequently Asked Questions

Should I choose OASI 30 or OASI 60 for a 12 V yacht with limited battery capacity?

OASI 30 is rated at 35 litres per hour and 14 A at 12 V; OASI 60 at 60 litres per hour and 38 A. The 60 produces water faster, but its higher current draw matters when planning battery use.

Can I order the OASI range for a 24 V electrical system?

Both OASI 30 and OASI 60 have 24 V DC versions. Their listed currents are 8 A and 20 A respectively; select the appropriate voltage version when ordering.

Do I need to add a remote control or automatic flushing to my OASI order?

Tecnicomar supplies the remote control, electronic control panel and automatic membrane flushing on request. Specify the functions you need in the order rather than assuming they are standard.

Is an activated carbon filter standard with OASI?

Tecnicomar lists the activated carbon filter as available on request. Include it in the specification if you want this additional treatment for the produced water.
