Applications
Heating and cooling in the engine room
On a ship, there are many types of machinery with a cooling demand. When the heat energy cannot be recovered or utilized, the total costs of transferring it away from the machinery should be kept to a minimum. Alfa Laval can ensure a cost-effective central cooling system through our portfolio of innovative plate heat exchangers. Our gasketed plate heat exchangers have unique features that reduce the running costs for engine room cooling – and contribute to sustainability.
LPG and ammonia cargo handling
The transport of LPG and ammonia require specialized cargo handling systems. Alfa Laval marine semi-welded plate heat exchangers are the ideal choice for the cargo condenser on refrigerated LPG and ammonia carriers, thanks to their very high efficiency and the ease of performing service on board. Semi-welded plate heat exchangers are also used as cargo heaters, while other heat transfer duties in the cargo handling system can be served by Alfa Laval CBM and/or AlfaNova heat exchangers.
Heating and cooling for methanol
As the marine industry decarbonizes, interest in methanol is growing and the first methanol-fuelled vessels are beginning to appear. Methanol is a clean-burning liquid fuel that enables carbon-neutral operations if produced from green sources. Yet it poses heating and cooling challenges compared to conventional fuels. Alfa Laval has the heat exchanger solutions to ensure safe and efficient work with methanol on board.
Marine refrigeration
Refrigerants are common in the marine industry, from chilling and freezing the catch on fishing vessels to air conditioning on cruise ships. Yet the refrigerant types are changing rapidly. Chlorofluorocarbon (CFC) and hydrochlorofluorocarbon(HCFC) refrigerants have given way to hydrofluorocarbon (HFC) refrigerants, and now many shipowners are exploring natural refrigerants like CO2. Alfa Laval has the heat exchanger solutions and expertise to support natural refrigerant choices.
