Product Description
The advantages of CO2 as a refrigerant
- Climate-neutral environmentally friendly refrigerant R744 (CO2)
- Without environmentally hazardous decomposition products
- No additional contribution to the greenhouse effect (GWP = 1
- Does not contribute to the ozone depletion (ODP = 0)
- No disposal and recycling requirements
- No availability constraints
- No taxes = long-term cost-efficient
- Low security requirements - Safety Group A1
- Non-toxic, non-flammable, thermally stable, compatible with other materials
