Alfa Laval printed circuit heat exchangers are an ultra-compact solution for improving sustainability in marine, oil & gas, thermal and renewable power applications (such as thermal energy storage systems, supercritical CO2power cycles, gas turbine fuel gas pre-heating andhydrogen refuelling stations, etc.).

Photo-chemically etched fluid micro-channels provide exceptionally high thermal performance, while state-of-the-art diffusion welding (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.

CCU/S will be fundamental for the future of the energy market in industries with limited options to decarbonize. Alfa Lavals heat transfer technology can maximize the efficiency of carbon capture.

Long-term, utility-scale storage enables the potential for renewable energy available 24/7. Alfa Lavals heat transfer technology is the core in cost efficient energy storage solutions.

At Alfa Laval, we can support you with highly efficient heat exchangers that maximize the filling capacity of your systems, as well as expert advice on how to optimize your hydrogen precooling process

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 full vacuum to 1,250 bar (18,125 psi).

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.

In renewable energy applications PCHEs are proving to be a great technology fit in high-temperature long duration energy storage (LDES) processes, as well as evolving niche positions in carbon capture.

Combining the proven advantages of our classic PCHE design with our 3DPlate anti-freezing technology also opens up use across the whole hydrogen refuelling station energy chain from liquid to gas. In hydrogen refuelling stations, Alfa Laval PCHEs are an ideal solution for precooling of hydrogen, offering possibilities to reduce filling times and wait times between refuels, while minimizing installation costs.

Printed circuit heat exchangers operate with two or more media on opposite sides of a diffusion welded 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.

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 welded (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, vent or cleaning form the welded header assemblies, which are welded onto the completed core to finalize the heat exchanger.

Design pressures of up to 1,250 bar (18,125 psi) in 304/316 stainless steel are achievable with this configuration.

Heat transfer surface areas are tailored based on requirements.
