Introduction
The gear unit can be equipped with a cooling coil in the oil sump. The cooling coil is connec-
ted to a cooling water supply. The cooling water connection must be provided by the oper-
ator. The cooling water can be fresh water, sea water or brackish water.
Principle of operation
Heat from the gear unit oil is transferred to the cooling water as it flows through the cooling
coil.
Information
To prevent the formation of condensation, make sure that the cooling coil is fully immersed
in the oil.
Improper use can damage the cooling coil. Be sure to take the following precautions:
• Make sure that the cooling water pressure does not exceed 8 bar.
The direction of water flow through the gear unit is optional.
• Make sure that the ends of the cooling coil are not twisted and that the reducing screws
are not removed or retightened.
• If there is a risk of freezing temperatures or the gear unit is to remain out of service for a
prolonged period, drain the cooling water out of the coil and blow the coil out with com-
pressed air to remove any water residue.
• Use a suitable cooling water flow regulator (e.g. a pressure reducing valve or an appro-
priate isolation valve) in order to prevent excessive water pressure at the cooling water
inlet.
WARNING
Risk of eye injury from compressed air
Water residue and dirt particles can cause damage to eyes.
Wear suitable safety goggles.
