Turning Waste Heat into Reliable Energy
We connect data centers and district-heating companies to create low-cost, low-carbon energy systems.
ABOUT OUR COMPANY
Growth through intelligent energy recovery
Calentix transforms excess heat from digital infrastructure into sustainable business value. By upgrading waste heat into high-temperature hot water, we replace costly and carbon-intensive heat production.
We deliver fully financed, turnkey projects that provide stable returns and measurable system benefits. With extensive experience in district-heating, large-scale heat pump integration, and digital optimization, Calentix manages the entire process. From opportunity assessment and design to operation and long-term asset management.
