Plate fin heat exchangers
including air separation plants, petrochemical and gas treatment plants as well as natural gas and helium liquefaction plants.
Our PFHEs are brazed in vacuum furnaces without using flux. This means that all cores are delivered completely free from corrosive residue and post-brazing cleaning steps are not required.
Highlights of our PFHEs : –
Tailor-made design
Proven vacuum brazing technology
High thermal efficiency through variable fin configurations
Aluminium alloys for optimum heat exchange between clean gases and liquids at low temperatures
Simultaneous heat exchange between multiple streams
Suitable for single-phase and mixed-phase fluids
Arrangement of streams in counter-flow, cross-flow or flow combinations
Wide range of fin types with different surface areas for optimised equipment design
Superior computer software for thermal and hydraulic design
Plate-fin heat exchangers can treat many process streams in only one unit thus avoiding expensive interconnecting piping of different units.
The aluminium alloys used for fabrication of brazed plate-fin heat exchangers provide best possible heat transfer, allow the application in low temperature service and reduce drastically the equipment weight to be supported.
Single-phase liquid and gaseous streams can be treated as well as vaporizing and condensing fluids.
Beside the usual counter-flow design also cross- flow arrangement can be realized.
Additional customer requirements can easily be considered, e.g. with regard to already existing pipe connections or support structures to be met.
