Because on board energy is both limited and expensive, Spectra created an innovative low energy RO process with a proprietary new technology. The Clark High Pressure Pump, which is featured in all Spectra systems, is versatile enough to be used in systems ranging from 150 gallons per day (GPD) up to 1,000 gallons per day.
Spectra watermakers require only 13 watt-hours per gallon. This is only 33% of the energy required by the best competitive technology! Another key benefit is the water output volume does not vary with water temperature changes.
Finally, because Spectra systems operate on low voltage direct current, they are ideal for many solar or wind-driven applications.
Spectra is dedicated to continually refining their technology making them the leader in energy efficient watermakers.

Newport 400 MKII
The Newport 400 MKII is the most technically advanced marine desalination system available today. Its two key innovations are:
- Two speeds of operation for onboard power management: When the engine or generator is running, the system can make lots of water in its high speed mode. For maximum energy efficiency, it can switch to the low speed mode when running on batteries or alternative energy. No other system has this feature!
- A revolutionary backwash system: The MKII backwash system actually creates a freshwater flow backward though the prefilters and strainer. Most systems only allow flow in one direction, trapping material in the filters. The MKII will produce flow in both directions, backward though the filters and forward to flush the pump and membrane. Backwashing the filters with fresh water helps prevent anaerobic bacteria formation, eliminating odors and extending filter life.
As with our other systems, the MKII comes complete with Spectra's proprietary Clark Pump. Its composite construction is corrosion resistant and convenient to use because there are no flow or water pressure adjustments. It is available in both 12V and 24V for safe, low voltage operation and virtually noise-free watermaking.
Ventura 150
Also known as "The Energy Miser," the Ventura 150 is designed and engineered for the smaller vessel. It is an affordable and compact watermaker with all the great features for which Spectra has become known.
The Ventura 150 is easy to install and use, quiet, very energy efficient, and it delivers over six gallons of fresh product water (24 liters) per hour. The machine’s composite construction is corrosion resistant for superior reliability and can produce 150 gallons a day!

The Clark High Pressure Pump
The Clark High Pressure Pump is a unique pressure intensifier that uses two opposing cylinders and pistons that share a single rod. Water pressure from the small feed pump is used by one of the cylinders to make the other pressurize and circulate the saltwater through the reverse osmosis membrane.
Pressurization is almost continuous because the process is instantly reversed when a driving cylinder's piston touches the base. There is no energy wasting "back stroke" like in other systems and no need for gears or crank shafts that need oil and servicing. All moving parts are made of non-corrosive materials.
