Conry Tech is reinventing air conditioning to make comfort sustainable. Conry Tech is a climate tech hardware manufacturer which has invented a revolutionary system that enables buildings to electrify, decarbonise, slash emissions, improve the comfort and health of its occupants, and which enables the clean energy transition. Conry Tech believe that energy conservation and energy efficiency need to be the top priorities in making built environment more sustainable. Air conditioning takes 60% of a buildings power, and yet AC systems are still basically the same as they’ve been for 100 years, and this must change if comfort is to become sustainable. This company is founded by Ron Conry, the award-winning inventor of the Turbocor compressor (the most significant technological breakthrough in the HVAC industry in over 40 years), and by Sam Ringwaldt, who has been at the forefront of sustainability and efficiency in the HVAC industry globally for over 20 years. The technologies invented and brought to market by Ron and Sam previously are now dominant globally, and have reduced HVAC systems power consumption by over 50%, radically changing the HVAC industry worldwide. However despite these achievements, they were previously constrained by how HVAC has been done for 100 years, and so this time they took a blank page and invented and patented an entirely new approach, and are bringing to this new technology to the market as Conry Tech. Conry Tech is Headquartered in Melbourne, Australia.
