and discover
your potential annual savings.
Our systems require only about 20% electricity, while the remaining 80% of the energy needed for heating or cooling is naturally drawn from the environment — air, ground, or water.
The technology operates through the compression and expansion of CO₂ gas in a closed-loop cycle, harnessing phase-change dynamics to generate heat or cooling efficiently.
Unlike traditional electric heating systems, where energy is consumed entirely from electricity,
our system recycles most energy directly from the surrounding environment.
This results in dramatically lower electricity consumption and operating cost reductions of up to 80%.
