Description
The system is designed with separate LT- and HT-
circuits and is fully integrated in the external system,
which can be a conventional or a centralized cooling
water system. With this system pumps and heat
exchangers can be common for propulsion and alt-
ernator engines. It is however, recommended that the
alternator engines have separate temperature
regulation on the HT-circuit.
Low Temperature (LT) Circuit
As standard the system is prepared for fresh water in
the LT system, with pipes made of steel and the
plates in the lub. oil cooler is made of stainless steel,
but as optional, sea water can be used provided that
the materials used in the system are adjusted ac-
cordingly.
