Serving the industry

Developed more than 50 years ago to meet the needs of the aeronautics industry, where compactness, light weight and efficient heat exchanges are essential qualities, brazed aluminium plate-fin heat exchangers now have an excellent reputation in the gas treatment industry following enhancements which have added to their initial qualities to meet the requirements of process engineers, investors and operators.

NORDON CRYOGENIE brazed aluminium plate-fin heat exchangers offer the possibility of integrating various processes (up to 20 fluids, flowing simultaneously through a single heat exchanger), highly efficient heat exchange with a low temperature gradient (a difference of only 1°C to 2°C is sufficient), for a wide range of dimensions.

The equipment's leak-tightness is ensured by the external closure bars. Before/After brazing The separating sheets between two passages are plated on both sides so as to provide the brazing metal required to bond all the parts.

The fin structure has two purposes: thermal conduction, pressure resistance.   More than 80 types of fins The Nordon Cryogénie catalogue contains more than 80 different types of fins suitable for various heat exchanger thermal and hydraulic performance requirements.

NORDON CRYOGENIE brazed aluminium plate heat exchangers are especially suitable for processes requiring a high-level heat transfer for a small temperature difference between the warm and cold fluids.

Some typical applications:

separation of air gases
separation of hydrocarbons
natural gas liquefaction
industrial gas liquefaction
(oxygen, nitrogen, argon, helium, etc.)

Improvements in the performance of modern processes have placed NORDON CRYOGENIE at the top of development in the field of controlling flows in heat exchangers, and designing and simulating the operation of equipment. NORDON CRYOGENIE is especially proud that its work is contributing to the growth of the gas industry all over the world. The heat exchanger’s many component parts are manufactured with the greatest care and assembled by vacuum brazing. Our fully automated installation optimizes the brazing process with outstanding reliability, whatever the size of the heat exchangers.

Inspection equipment incorporating the latest technological advances ensure the product’s impeccable quality.

NORDON CRYOGENIE’s expertise covers the supply of assemblies in cold boxes including the piping and instrumentation required to run the process.

NORDON CRYOGENIE takes charge of the installation of heat exchangers, from engineering through to welding and final inspection, for new units and for revamping projects.

A team of experienced specialists provides technical assistance for operators all over the world.
