3.7 Advantages of the Energy recovery system
Introduction
Thank you for choosing a Schenker Watermaker.
As all the equipment, the knowledge of operating and maintenance procedures allows to use the system in the
best way, and to guarantee a perfect functioning throughout the years. We invite you to read carefully this
manual and to keep it for a quick reference.
Functioning principles
The Schenker watermakers, as alternative to the high-pressure pumps of traditional systems, utilizes the
ENERGY RECOVERY SYSTEM patented device, which amplifies the pressure of common low-pressure
pumps, and recoup all the hydraulic energy back from the membranes, allowing a high energy efficiency.
The lack of high-pressure pumps makes the system silent and vibrations free, and enormously simplifies the
use as no adjustment is necessary for its operating.

The watermaker group is composed of the following parts:
•Reverse osmosis membranes
•Energy Recovery System
•Manometer
•Accumulator
•Depressurization valve
•Positioner
•Reset valve
•High pressure switch
Reverse osmosis membrane. It is installed inside the glass fibre high-pressure housing. Membrane is n.1 x
SW2521 type. Its purpose is to separate the intake high-pressure seawater in two flows: one for the salt-water
drain and one for the fresh water production.
Energy Recovery System. It is the black, carbon fibre unit. It has the function to amplifythe pressure supplied
by the pumps and to recoup the hydraulic energy back from the membranes. The ERS device makes periodic
cycling by a hydraulically controlled automatic valve. The cycles are noticeable through a ”beat” issued
periodically by the watermaker unit. The unit is based on cylinders and a central body containing the hydraulic
valve necessary for the system functioning.
Manometers. It is located on the front panel of the watermaker, and it measures the working pressure of the
watermaker.
Accumulator. It is a black plastic reservoir of air, installed in the pump group. Its function is to reduce and
stabilize the pressure peaks during the watermaker functioning. The device has to be pre-charged with air
through the specific valve. The air pressure precharge is about 4 Bar. The pressure dimmer is charged in
factory at the right pressure.

Depressurization valve. It is used for the air bleeding of the unit. It is recognizable by a blue lever and it is
located on the top side of the watermaker fitted on the top valve of the ERS. Its function is to depressurize the
system and to allow the bleeding of air. The valve must be closed during normal working conditions (vertical
position), and it is opened during the air bleeding operations (horizontal position).
Positioner. It is a stainless steel threaded arm, with a black knob, located on the right side of the watermaker.
Its function is to reset the unit in case of hydraulic block.
Reset valve. It is installed on top of the ERS it is recognizable by the little blue plastic lever. The valve must
be closed during normal functioning (lever perpendicular to the valve). Such valve has the function to allow the
reset of the ERS in case of a system block. It must be opened before acting on the valve positioner.
High pressure switch. It Is hydraulically connected with the pump group. It stops the system if the pump
pressure exceeds 9,5 bar. In this case a high-pressure alarm is activated on the control panel.
3.8.3 Accessories
The main accessories of the watermaker are the following:
•Active carbon filter
•Electrovalve
•Non-return valve
•Mesh filter (strainer)

4. MOUNTING AND INSTALLATION
4.1 General criteria
Before starting with the installation, it is important to carefullyplan all the activities, by evaluating all the possible
solution to be adopted. The main points to focus on are the following:
•Individuate the seawater inlet
•Positioning of the main units (pump group, watermaker group, active carbon filter).
•Positioning of the thermal-magnetic circuit breaker.
•Passage of the hoses and electric cables.
CAUTION
For a correct installation of the watermaker, in order to avoid issues along the different ways
of operating condition, please follow carefully the general instruction below:
•Consider to install the through-hull fitting in a central and deep position, in the way that no air
could be aspirated.
•The non-return valve has to be installed under the seawater level and as close as possible to
the through-hull fitting, in vertical position.
•The pump must be installed as low as possible respect to the seawater level and as close as
possible to the seawater intake (through-hull fitting).
•The watermaker unit must be horizontally positioned, and arranged on an adequate support
which is able to sustain the weight (about 25 Kg).
CAUTION
The pump group must be installed in a ventilated place, in order to facilitate the cooling. In
addition to this, a place not exposed to condensation and dripping should be adopted.
ATTENTION
The external surface of motor and pump can reach high temperature; therefore, it is
recommended to avoid any contact with inflammable liquids and materials.
NOTE
Once individuate the correct installation solution, it is recommended to first make a schematic
draft of the hydraulic and electric connection, and attach them to the present manual for future
needs as first reference.

4.2 Components mountings
4.2.1 Pump group
The diaphragm pump must be installed as low as possible respect to the seawater level and as close as
possible to the water inlet; furthermore, the pump cannot run dry.
The pump group should be installed in an adequately ventilated room, with the purpose to facilitate the cooling
of the motor, and not subject to condensation or drippings. The max permitted room temperature must not
exceed 45°C.
Avoid the contact or the proximity with inflammable material or liquid, since the motor surfaces can reach
elevated temperatures. Avoid locating the pump wherever a possible loss of water can involve damages or
jeopardize its safety. The pump must be installed on a base sufficiently horizontal, suitable to sustain the
weight of the group. The pump is normally fixed on the support structure by passing bolts.
4.2.2 Watermaker group
Concerning the watermaker unit installation there are not height limits respect to the seawater level. Anyway,
it should be installed above the pump.
Avoid to install the system wherever any possible leak may cause damages to the vessel or jeopardize its
safety, since possible leaks due to accidental causes (hose bursting, hose clamp loosening, equipment failure,
etc.) may cause water losses.
The hydraulic intake and outlet connections are positioned on the left of the unit. Therefore, it is necessary to
foresee a minimum distance of 20 cm. to allow the hoses laying. The watermaker unit must be installed on a
base sufficiently horizontal, suitable to sustain the weight of the group. The max allowed room temperature
must not exceed 40°C. It is advisable to install the unit in such position to make the instrumentation easily
visible, and make the valves (located on the right of the unit) easily accessible. The watermaker is normally
fixed on the support structure by passing bolts.
4.2.3 Accessories
The non-return valve has to be installed vertically as close as possible to the seawater intake, following the
direction of the arrow.
The active carbon filter (and the attached electrovalve) has to be placed next to the pump group, if possible,
on a vertical side easily accessible.
