Cooling; Keel Cooler - Vetus EP2200E Instructions D'installation

7 Propeller
Design of the propeller and propeller aperture are very important for
the cruising characteristics of the vessel. It is especially important for
a vessel with electrical propulsion that the propeller size is selected
correctly.
• Consult table 1 at page 54 for selecting the correct propeller.
When running forward, the electric motor shaft must turn to the
right, when viewed from the back.
• Fit only a 'R h ' propeller!

Cooling

In order to achieve the highest possible efficiency both the electric
motor and the speed regulator are fluid cooled. The efficiency of
electrically driven motors and speed regulators is to a large extent
influenced by the temperature and increases at a lower temperature.

The cooling system is a so-called 'keel cooling system'; a cooling liq-
uid circulates around the motor and along the speed regulator.
N.B.: If a hybrid installation is being used the diesel engine must
have its own cooling water supply.

8.1 Keel cooler
The keel cooler must be positioned on the outside near the bottom
of the hull.
When selecting a position for the keel cooler the following point
must be taken into account:
- The keel cooler must be placed in such a position that a continu-
ous flow of water is guaranteed under all circumstances.
- This means that placing it near to the bows where turbulence can
occur at higher speeds is not advisable.
7
- The keel cooler must also remain under water when the ship rolls.

• Fit the keel cooler using the packing rings (A), the rings (B) and the
nuts supplied.
• Use a sealant when fitting the keel cooler to the ship's skin.
