Alfa Laval printed circuit heat exchangers are an ultra-compact solution for improving sustainability in marine, energy and oil & gas applications. Photo-chemically etched fluid channels provide exceptionally high thermal performance, while state-of-the-art diffusion bonding produces a solid core packed with heat transfer area. The combined result is maximum efficiency and minimum footprint, ensuring the lowest total lifecycle cost. Applications Alfa Laval printed circuit heat exchangers are designed specifically to deliver unparalleled compactness and efficiency in clean and high-pressure duties that are beyond the capability of other welded plate type heat exchangers. The robust design can reliably handle pressures ranging from vacuum to 1000 barg (14,500 psig). Typical marine applications include high-pressure vaporization in fuel gas supply systems (FGSS), LNG regasification on FSRU and SRV™ vessels. In the energy sector, printed circuit exchangers are used in gas processing and cryogenic LNG applications. Typically, these are gas compression systems offshore, hydrocarbon gas and water dew-pointing. In LNG, where high energy recovery is desired, they are used in End Flash Gas and BOG handling systems. They can also be found in turbine fuel gas preheating and supercritical carbon dioxide (sCO2) applications for power generation.

Working principle Printed circuit heat exchangers operate with two or more media on opposite sides of a bonded plate. It is possible to have high-pressure flows on both sides, and a 2D or 3D plate pattern can be optimized to provide the required thermal length and pressure drop. Design The printed circuit heat exchanger design has a complex flow pattern chemically etched on flat sheets of material. This flow pattern is optimized for each specific customer duty to provide the required thermal and hydraulic characteristics. Each flow circuit plate pattern can be different, giving the possibility of asymmetric flows and optimized 2-phase behaviour. The individual plates are then stacked into a block and diffusion bonded in a state-of-the art furnace at high temperature and pressure. Multiple blocks can be welded together to create the required thermal capacity or heat transfer area. Inlet and outlet flow manifolds, customer connections and (if required) connections for drain, ventilation or cleaning are welded onto the completed core to finalize the heat exchanger. Design pressures of up to 1000 barg (14,500 psiG) in 316L SST are achievable with this configuration. Heat transfer surface areas are tailored based on requirements. .
