Additive Manufacturing Liquid-to-Liquid Heat Exchangers

Industry-leading 3D printing technology for ultra-high performance.

Superior Thermal Exchange

Enhanced surface area density to volume ratio results in significantly higher thermal exchange performance, ensuring efficient heat transfer for your critical applications.

Optimized Flow Efficiency

Micro-structures and complex internal geometries ensure low pressure drop, enhancing system performance through efficient, smooth fluid flow and optimal heat transfer.


Monolithic designs not only significantly reduce overall weight but also simplify maintenance with fewer parts to manage, streamlining system serviceability.


Morphed topology offers unmatched design freedom. Tailored to fit available spaces, providing flexibility in form factor and enabling seamless integration into a wide range of systems.

Enhance performance with a 3D printed liquid to liquid heat exchanger

Our liquid-liquid heat exchangers feature our exclusive patented additive manufacturing technology incorporating years of expertise in thermal transfer.

    • We use high quality metal powders, and recommend AlSi10mg, an aluminium alloy chosen for its strength and reliability. We can print in other materials based on customer requirements.

    Thermal Applications include:
    • oil-oil
    • oil-water
    • oil-glycol
    • water-water
    • fuel-oil

The Conflux Cartridge: Designed as drop-in replacement for micro-tube heat exchanger

Designed to fit within a traditionally manufactured part or casing, such as a gearbox.

The Conflux team set out to design and manufacture a cartridge heat exchanger for oil cooling applications, to match or exceed an incumbent micro-tube heat exchanger for a transmission application. The team achieved remarkable results, demonstrating that the cartridge design could be applied to other applications and at a reduced price-point.
