Alfa Laval Equipment Enhanced
Heating and cooling in the engine room
Alfa Laval gasketed plate heat exchangers for engine-room central cooling systems, with titanium central coolers on seawater and excess jacket water heat usable for AQUA Blue freshwater generation.
Description
Heating and cooling in the engine room covers Alfa Laval plate heat exchangers for cost-effective central cooling systems on ships. Gasketed plate heat exchangers reduce the running costs of engine-room cooling.
Central cooling system
- Removes heat from jacket water, lubricating oil, diesel oil and charge air coolers, auxiliary engines and ancillary equipment
- Seawater from the sea chest passes through a coarse strainer to titanium central coolers and then overboard
- Fresh water circulates through the central coolers with a bypass regulation valve to keep the low-temperature circuit at constant temperature
- Part of the excess jacket water heat can produce fresh water in an Alfa Laval AQUA Blue freshwater generator
