This trend is driven by several factors, like:

benign refrigerant properties in terms of environmental sustainability (GWP = 3-5).

higher system efficiency and higher COP when compared to standard technology.

high familiarity with the gas.

In particular, clear signals from the market are arising, with an increasing demand for larger compressors for industrial and commercial applications.
