Semper Pürus Automated Watermaker

Financing Available. The Semper Pürus automated water makers will revolutionize the concept of small, light-weight water maker systems. Available as a portable unit built inside a heavy duty wheeled case or as a permanent mount installation, this system has the ability to make up to 30 gallons of water per hour. Semper Pürus engineering uses industrial level control techniques and components to ensure extreme reliability while maintaining an easy-to-use, simplistic approach to operating the system. A touch screen is utilized to access all functions of the unit, and all aspects of the water making cycle are automatic. Continuous pressure regulation, water quality monitoring, and production rate are part of the automatic system and are displayed in the graphic animations on the touch screen. Systems with capacities up to 20 gallons per hour can be run from a 4 KW inverter and VFD controlled start technology is available for the high pressure pump on the larger units. The small footprint makes it easy to find a location for the components, and the system is a breeze to service. Turn it on, push a button, and walk away. The system will handle everything from activating pumps to automatically flushing itself when the cycle is complete.

Pre Sale Questions

Water maker systems work by utilizing an extremely fine filter called a membrane through which raw water is pushed via a high pressure pump. The membrane only permits water molecules to pass through and rejects 99.9% of everything else including salt, bacteria, and most viruses.
As a guideline, most cruisers use 20 gallons of water per day per person. If you are planning on having 2 people on board, you should have a minimum of 40 gallons per day available. For 2 people a 20 gallon per hour water maker is sufficient.
It is not recommended to make water while underway because of the chance of drawing fuel or oil into the system which would destroy the membrane.

Most Asked Technical Questions

All filters should be changed annually even if they do not need to be changed.
You will need a 20 amp dedicated electrical service. space for the equipment, a minimum of 1 thru-hull but 2 are recommended, and a clean, dry environment for the control system
With proper maintenance the membranes should last for 5-10 years.
There is very little maintenance on our system. However, there are some checks to do and are listed in the user’s manual. Some checks include looking at the piping and valving once per month and, even though the system establishes the pressure automatically, you should visually verify the pressure every 10th use.
