Catalina 300 MK

One of the Simplest, Most Energy Efficient Marine Watermakers Available Today

Spectra Watermakers' Catalina 300 MKII is one of the most technologically advanced marine desalination system available today. Utilizing the experience gained from over ten years of building the world's most automated, energy efficient watermakers, Spectra has taken the popular Catalina 300 to another level of efficiency and reliability.

The Catalina 300 MKII is designed and engineered for maximum reliability, efficiency, and ease of service. Available in both 12 volt DC or 24 volt DC configurations these systems have the versatility and safety of low voltage operation and are one of the quietest running watermakers available.

The MKII is more compact than its predecessor because the 50 micron filter has been eliminated in favor of a small filtration boost pump. Also, the dual 20 and 5 micron filter combination gives way to a single 5 micron filter located in front of the feed pump module. This arrangement allows the system to be located in a wider variety of locations and enhances the filtration to the feed pump. Installation is also easier and faster because the MKII has less wiring and centralized plumbing connections. The MKII features the same stalwart Spectra MagDrive™ feed pump as its predecessor coupled to a time proven DC motor.

Yet another innovative feature of the Catalina 300 MKII is that it has been designed with a true pre-filter backwash system. The MKII backwash system actually creates a freshwater flow backward though the prefilters and strainer. Most systems that flush with fresh water only have flow in one direction, trapping material in the filters. The MKII will produce flow in both directions, backward though the filters then forward to flush the pump and membrane. Backwashing the filters with fresh water helps prevent anaerobic bacteria formation. This not only eliminates the foul odors that can develop in conventional freshwater flushing, it also keeps filters cleaner and extends overall filter life.

Spectra's most recent major technological advancement in control systems is the new MPC- 5000. The MPC 5000 has all of the features of the well known industry standard MPC- 3000, but sidewith more accurate instrumentation, more features and enhanced reliability. With the MPC 5000 just set the desired run time and forget it, the MPC 5000 controller will do the rest. All of the control and instrumentation functions are displayed on a panel located in a convenient space such as your navigation area, away from the watermaker.

The MPC 5000 displays pre-filter condition, feed water pressure, water tank full status (with optional tank switch), product water quality, product flow rate and total system hours. The display can be set for either US standard or metric readouts. One touch to the MPC 5000 touch pad sets the Catalina 300 MKII in motion. During startup, the reject water is automatically diverted back to the ocean by the controller. The desired amount of water then fills the storage tank, the system back washes itself clean and shuts itself off. The MPC 5000 controller can keep the MKII in a fresh water storage state by backwashing every five days as long as needed. Just set it and forget it!

The MPC 5000 is fully programmable in the field by the owner or technician without special tools or computer connections. With its "mission critical" design, the MPC 5000 is engineered to keep the machine running even in the event of a critical alarm state. The system also has a full manual override in the rare event of a total control failure.

Leaving the vessel for a while?

Just press the Auto-Store button and the MPC-5000 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.

Another Spectra Exclusive the Z-Brane™ keeps your system clean without chemicals. Top off your Spectra System with the new Z-Brane™. This revolutionary technology keeps your Spectra Watermaker clean and free of bio-fouling and scaling. Cleaning with chemicals substantially shortens the usable life of reverse osmosis membranes.
