PRINTED CIRCUIT HEAT EXCHANGERS
High-performance compact exchangers for extreme process conditions
High-performance compact exchangers for extreme process conditions
Printed Circuit Heat Exchangers (PCHE)
Printed Circuit Heat Exchangers (PCHE) combine extremely high heat transfer efficiency, unmatched compactness, and robust mechanical strength, making them ideal for high-pressure, high-temperature, and space-constrained applications across industries such as hydrogen, LNG, aerospace, nuclear, and chemical processing.
PCHEs are manufactured using advanced micro-channel and diffusion bonding technologies. Micro-channels (as small as 30 microns) are chemically or mechanically etched into metal plates, stacked, and then bonded using vacuum diffusion welding. This process results in a monolithic structure with no joints or seals, capable of withstanding pressures up to 100 MPa and temperatures from –253°C to +1000°C.

Our Printed Circuit Heat Exchangers (PCHE) are manufactured by stacking chemically or mechanically etched metal plates that form ultra-fine microchannels. These plates are bonded using vacuum diffusion welding to create a compact, monolithic structure. The channel geometry, fin type, and flow configuration are fully tailored to meet each customer's process requirements, including flow rates, pressure drops, media properties, and temperature approach. This micro-scale design delivers outstanding thermal performance in a minimal footprint. The turbulent flow generated inside the microchannels enhances heat transfer efficiency while reducing equipment volume and fluid inventory. PCHEs are designed to operate at pressures up to 100 MPa and temperatures from 253°C below zero to 1000°C. They are ideally suited for demanding applications in hydrogen, LNG, nuclear, aerospace, and advanced energy systems.
