Catalina 300

The Catalina 300 is affordable, light weight and compact with all the great features Spectra has become known for. The Catalina is easy to install, simple to use, quiet, very energy efficient and it will deliver 12.5 gallons (47 Liters) per hour while running on 15 amps at 12 volts DC. Catalina 300’s modular construction allows for easy owner installation and is ideal for those limited spaces on cruising and racing vessels where more water is needed.

With the Catalina 300 on board, there is no reason to compromise your creature comforts while cruising. You will have plenty of fresh water for boat and gear.

Spectra’s exclusive high pressure Intensifier maintains the proper pressures in the system’s membrane throughout a wide range of ocean temperatures and water conditions without any adjustments or loss of product water output. The tough composite construction is corrosion resistant for superior reliability.

Every Catalina 300 comes complete including the ultra reliable and efficient SpectraMag™-Pump. The Spectra High Pressure Intensifier is factory mounted with a 40 inch membrane in a Spectra high-pressure vessel assembly. High-pressure piping is pre-plumbed at the factory. The module brackets allow for installation in any orientation. All you provide is the two thru-hull fittings and electrical hook up. A One Year Complete Limited Warranty is available through our world wide distributor network.

MPC-3000 Controller

Simple one button operation
All Catalina 300 functions are displayed in a 5.25" x 3.75" control display panel located in a convenient space of your choosing away from the watermaker. Multiple control display panels can be added for even more monitoring convenience. The electrical control box has a built-in manual override so the watermaker also works without the MPC-3000 electronic control.

Just set it and forget it!

MPC-3000 displays the pre-filter condition, feed water pressure, water tank full status (with optional tank switch), product water quality, flow rate and total system hours. One touch to the MPC-3000 touch pad sets the Catalina 300 in motion. Reject water is automatically diverted back to the ocean by the MPC-3000 controller, the desired amount of water fills the storage tanks, the system flushes itself clean and shuts itself off. You can set the controller to keep your Catalina 300 in a fresh water storage state for as long as you like.

Leaving the vessel for a while?

Just press the Auto-Store button and the MPC-3000 controller will do an automatic flush every 5 days. No more worries about messy storage chemicals. And when you return to your vessel, your system is ready to start up and go.

Z-Brane™ keeps your system clean without chemicals. Top off your Spectra System with the new Z-Brane™. This revolutionary technology keeps Catalina 300 clean and free of bio-fouling and scaling. Cleaning with chemicals substantially shortens the usable life of reverse osmosis membranes. The Z-Brane™ eliminates the need for harsh chemicals used to clean and store your watermaker.

Ask your distributor about the Z-Brane™ and Z-Guard™ protection systems.
