The traditional reverse osmosis watermakers make use of high pressure pumps. The high pressure pumps are necessary to increase the pressure of the seawater (up to 50-60 BAR) and activate the reverse osmosis process, producing freshwater. High pressure pumps consume a great amount of power. For instance, to produce 60 lit/hour of freshwater, the consumed energy is, on average, 1.5 - 2.0Kilowatts. Most traditional watermakers need a 220V generator onboard.
Schenker watermakers, use a new device (Energy Recovery System)
that amplifies the pressure supplied by low pressure pumps and recover
most of the spent energy, This enables very high energy efficiency. The
consumed energy is up to 80% lower than a traditional system (example:
only 240watts to produce 60 lit/h). Thanks to this high efficiency, Schenker
watermakers are powered directly from service batteries, without the need
for a generator.
The main advantages of this new technology are summarised below:
Direct
power supply from service battery (12 or 24 VDC). A generator is not necessary.
Very
low electric consumption ( less than 80% of a traditional system. i.e.
only 100 watt for 35 lit/h).
Materials
used are totally corrosion free
Self
regulating pressure
Very
quiet running and vibration free.
High
reliability, thanks to the reduction of moving parts and slow cycling.
The
most compact dimensions in its category (i.e. 68X 24X24 cm - 35 lit/h
Smart model).
Excellent
value for money
Working
flexibility. The 60lt unit consists of a two stage pump. It is so possible
to activate a single stage, thus obtaining a 30 lit/h consuming only 100
watt, or activate 2 stages, obtaining full production (60 lit/h) consuming
240watt.
Working
simplicity. There are no valves to regulate or operations to carry out.
All at the flick of a switch.
Electron
version available. This version is controlled by a micro computer that
performs all the functions, including the fresh water washing. A remote
panel includes all the commands.
These advantages make the installation of a water maker possible on small to medium boats without generators, solving the problem of water supply, widely increasing safety and comfort on board.
