Snapshot of Projects

In 2009 Yunca were approached by the Light Metals Research Centre (LMRC) at the University of Auckland to support development of the LMRC Heat Exchanger technology for application inside aluminium smelters. Yunca was asked to design the clamping/mounting system to quickly and easily mount the exchangers onto the pot shells, design a balanced duct and extraction fan system, and design the exchanger mechanism.

In close association with LMRC the two parties successfully developed the EnPot Heat Exchanger technology to the point it was successfully installed on 128 pots at TRIMET Essen Smelter in Germany.

In 2025 the EnPot Technology was installed on the Binzhou Beihai Smelter in Shandong, China - owned by the second largest producer of aluminium globally, China Hongchiao Group. Yunca retain the contract manufacturing rights for the critical components of the Shell Heat Exchangers continuing to support the worldwide application of the technology, via EnPot Ltd

Solhaus is a new project from Yunca Engineering, applying our design, build and manufacturing capability to high-end tiny homes.

Launching in Australia and New Zealand in 2026, Solhaus responds to a gap in the market for people who want to go small, but do it in a home that prioritises quality, design and liveability.

A smaller footprint, built to a higher standard. Quality materials, high-end fittings, efficient to run, and designed for how people live today. Solhaus is about redefining what small living can be, we’re proud to be launching these homes soon

The science behind the Hydrogen Califont heating system was developed by Callaghan Innovation and involves using photovoltaic electricity generated from solar panels, to separate and capture hydrogen from cold water. The stored hydrogen is then used for water heating.

Yunca were approached by Callaghan Innovation to develop the water heating system for this project. Hydrogen is a notoriously difficult product to use in water heating systems. Yunca took a commercial approach and built a prototype conversion kit to convert existing water heaters from natural gas to Hydrogen, rather than develop a bespoke unit.

Yunca has been awarded the manufacturing, distribution and marketing rights for the Hydrogen Califont water heating conversion system.

"Callaghan Innovation has been working with Yunca for a few years now on the Hydrogen Califont heating system, and has been impressed with how they have interpreted the science and come up with solutions for the water heating system… we have a great deal of confidence in Yunca’s forward thinking and background expertise when it comes to energy conversion and thermal systems." - A I Gardiner, Research Engineer, Callaghan Innovation
