Revolutionizing heat transfer with cutting-edge diffusion bonding

In industries where pressure, temperature, and reliability can’t be compromised, AIC’s diffusion bonded heat exchangers offer a next-generation solution. These diffusion bonded units are engineered for exceptional thermal performance, compactness, and endurance in even the harshest operating environments.

Why choose diffusion bonded heat exchangers?

Engineered for extreme conditions – designed to withstand high pressures (up to 1000 barg) and temperatures ranging from cryogenic levels to 800 °C.
Compact and lightweight – diffusion-bonded microchannel technology enables a footprint up to six times smaller than traditional shell-and-tube heat exchangers.
Exceptional thermal efficiency – achieve temperature approaches as close as 1 °C for maximum heat transfer.
Seamless, solid-state structure – diffusion bonding creates a permanent joint with no gaskets, welds, or fillers.
High corrosion resistance – compatible with aggressive media when manufactured in stainless steel, titanium, or nickel alloys.
Flexible configurations – custom-built to your process with concurrent, counter-current, and cross-flow designs.
Eco-friendly performance – long service life and energy-efficient operation help reduce your carbon footprint.
Customisable solutions – built to spec with tailored sizes, nozzle layouts, and material selections.

Diffusion bonded heat exchangers are manufactured using a solid-state metal joining process in which atomic diffusion under high heat and pressure creates a seamless, defect-free structure. This advanced diffusion bonding technology ensures outstanding durability, exceptional heat transfer performance, and superior resistance to thermal and mechanical stress.

Material preparation – precision-layered materials are prepared and aligned for diffusion bonding.
Bonding under heat and pressure – atomic diffusion occurs uniformly in a vacuum or inert atmosphere, forming solid joints.
Solid-state structure formation – no welds, fillers, or gaskets; only pure metallurgical strength.
Final testing and quality control – ensuring full thermal, mechanical, and structural integrity.
