With capabilities and performance unrivalled by other plate type heat exchangers, Heatric's diffusion-bonded heat exchangers offer a compact alternative to traditional methods of heat transfer.
By offering customised heat transfer solutions, Heatric has built a reputation for innovation in process optimisation. We work closely with our customer to provide the most efficient heat exchanger for any application, with diffusion-bonded heat exchangers combining the process benefits found in compact equipment with the performance of shell and tube heat exchangers.
Something for everyone...
High temperatures
Flexible fluid pressure drop More bang for your buck... Close approach temperatures High effectiveness Functional integration Three into one will go... Multi-fluid contact Injection of fluids Two-phase fluids Safe and sound... Diffusion-bonded heat exchangers are not susceptible to hazards commonly associated with shell and tube exchangers, such as flow induced tube vibration and tube rupture. As such, overpressure relief systems can be substantially reduced. Their highly compact nature means Heatric exchangers have a relatively low inventory when compared to shell and tube heat exchangers.
High pressures
Diffusion-bonded cores are designed for the containment of exceptionally high pressures and are readily designed for operating pressures of more than 600 bar (9000 psi).
Materials of construction, such as austenitic stainless steel allow temperatures from cryogenic to 900°C (1650°F).
Despite the compact nature of diffusion-bonded heat exchangers, there is no restriction on the pressure drop specification for fluids passing through them, even with gases or highly viscous liquids. Whilst the passages are small relative to conventional equipment, they are also short.
Fluid contact can be counterflow, crossflow, coflow or a combination of these to suit the process. Counter current design enables deep temperature crosses and temperature approaches of 3-5°C.
Diffusion-bonded heat exchangers have met process requirements for high thermal effectiveness in excess of 98% in a single compact unit. High effectiveness heat exchangers can reduce duty, size and cost of other heating/cooling operations in the overall process scheme.
Diffusion-bonded hardware is not restricted to heat exchange - it can also incorporate additional functions, such as chemical reaction, mass transfer and mixing.
Plate type heat exchangers are capable of containing more than two process streams in a single unit. Diffusion-bonded heat exchangers can be designed to incoporate this feature into high temperature and pressure processes. Multi-stream heat exchangers have obvious space and weight advantages through reduced exchanger and piping weight. Also process control can be simplified or eliminated. Fluids can enter or leave the heat exchanger core at intermediate points and can be connected in series or in parallel, allowing flexibility on inlet/outlet temperatures.
The unique construction of diffusion-bonded cores enables the accurate injection of one fluid into another, passage-by-passage.
Diffusion-bonded heat exchangers handle boiling and condensation of fluids and can also be employed in more complex duties involving absorption and rectification. It is also possible to evenly distribute two-phase inlet streams in the core.
