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
