Compact, efficient heat exchangers
• Cooling achieved by alternating hot and cold channels of liquids
• Channels formed by perimeter gaskets
• AL Flex pattern mixing optimizes heat transfer and pressure drop
• One-quarter the size and weight of shell & tube coolers

Advanced Plate Design
• Single-step pressing
• Patented distribution area design ensures better distribution
• No “dead spots” and reduced fouling
• Five-point guiding system prevents displacement

Gaskets that stay sealed
• Special materials, advanced designs
• One-piece moulded gaskets
• Protective gasket groove
• Separate fastening and sealing
• No interleakage
• Long gasket lifetimes
• Changed in the field Alfa Laval glue-free gaskets

Cooling with plate heat exchangers
• Multiple cooling duties
• Compact; low weight
• Low hold-up volume
• Less service space
• Easy to service
• Vibration and shock resistance
• No welds

Cooling Circuits
• Central Cooling System
• Low temp seawater cooled heat exchanger
• All other heat exchangers fresh-water cooled, heatload captured in central, low temp cooler
• Reduced seawater piping, corrosion, fouling and maintenance; eliminate many seawater coolers
• Seawater Cooling System
• Seawater passes through all heat exchangers in parallel or series
• All heat exchangers required to be resistant to seawater
• Extensive seawater piping
• Larger flow seawater pump

Reliable PerformanceCentral Cooling System • Limits components exposed
to seawater
• Smaller seawater pump
• Lower corrosion risk
• Freshwater cooled charge air coolers
• Lower system cost
• More reliable

Expansion Tank, multi function
• Permits expansion of coolant during engine operation
• Holds needed excess coolant
• De-aerates coolant
– Passive design provides extra volume for air to separate and rise to top of tank
– Active design uses cyclone to force air from the coolant
• Designed in integral piping, mounting, etc., providing cost, weight and space savings and an overall neater engine design

Passive Deaeration
• Large horizontal tank area for improved de-aeration
• Integrated piping
• Coolant level sensor mount
