The technical principle of operation:

The technical operating principle: A subcritical CO2 gas flows into a two-stroke gas expander engine via the cylinder space onto a piston and releases its potential energy. In the expansion stroke, the gas cools down to minus 55°C and is liquefied in the subsequent compression stroke. The liquefied low-temperature gas flows through a heat exchanger and extracts heat energy from the environment (air or water) to re-enter the gas phase. This allows the cycle to start again from the beginning.

The innovative and environmentally neutral result of this subcritical CO2 cycle process is, in addition to the motor drive energy for electricity generation, additional cooling energy with a temperature of up to minus 50°C, which can be used for cooling or even snow production, for example.

This makes the system particularly suitable for snow production with very low water consumption and environmentally neutral power generation.
