  • High cooling capacity by volume (5 to 7 times higher compared to ammonia);
  • Smaller operating volume of the compressor and smaller pipe diameters;
  • High coefficient of performance (CoP) at condensation temperatures lower than the critical CO² point;
  • Low viscosity and smaller pressure loss as a result;
  • High heat transfer coefficient for evaporation and condensation (60% higher than with HFKW);
  • Good compatibility with common materials and refrigerator oils and much more.
