The Mix with Mick Liubinskas 
About Tia Collings
Tia Collings is co-founder and CEO of Enaxiom, an Australian deep-tech company commercialising HydroCool, a regenerative cooling system for data centres. HydroCool rejects heat while recovering fresh water as a by-product, avoiding the evaporation losses of conventional cooling towers, and can connect to industrial wastewater treatment and green hydrogen production. Enaxiom was formed in late 2023 to bring to market technology that co-founder and CTO Bijan Rahimi had developed over about a decade. In May 2026 it announced a seed round backed by investors including Antler.
Collings came to hardware from sustainability consulting. On The Mix with Mick Liubinskas, she discussed using HydroCool in mining, data centres and green hydrogen, and the challenges of scaling hardware.
