CO2

CO2 or R744 provides an eco-friendly alternative to standard refrigerants using hydrofluorocarbons (HFC’s) which will eventually be required to be phased out of all refrigeration systems. CO2 is a component of our atmosphere that is essential to life. The environmental impacts and benefits of installing a CO2 system are endless. It has zero ozone depletion potential, negligible global warming impact (CO2 has a Global Warm Potential of 1 vs R404A that has a Global Warming Potential of 3,922), non-flammable, and non-toxic. It has no regulatory liability, there is no need to account for the amount used, and it does not need to be reclaimed. CO2 is readily available, non-poisonous, and an inexpensive refrigerant.

  • CO2 is ~70% cheaper than HCF refrigerants
  • Excellent heat transfer coefficient
  • GMP of 1
  • Low compression ratio (20% to 50% lower than HFC’s)
  • Relatively insensitive to pressure losses
  • Very low viscosity
