Electrical preheating of coolant
63
If required, the engines can be equipped with an electrical coolant preheating system.
Purpose and function of coolant preheating
Coolant preheating is designed to facilitate starting the engine when external temperatures are low and to
ensure the availability of the full power output immediately after a cold start (warm−up phase not required).
For this purpose, the coolant is preheated with the engine at a standstill. Preheating is made by an
electrical heater that is supplied from the AC power grid on land.
