COOOL R717

COOOL R744 is a natural refrigerant gas, with multiple applications in commercial refrigeration, the food industry and refrigerated logistics.

Its main characteristics are:

  • High refrigerating power
  • Higher quality than the specifications required by the regulations
  • GWP - Global Warming Potential = 1
  • ODP - Ozone Depletion Potential =0
  • No legal limits on use
  • No need for disposal

Thanks to the innovative biogas upgrade technology developed by the SIAD group's subsidiaries, COOOL R744 comes from renewable sources, a unique feature on the market.

SIAD has developed a special tanker truck for loading large systems, equipped with an on-board skid, which allows the system to be pressurized with CO2 in the gaseous phase and then loaded with the liquid phase in a single operation. For maintenance on R744 plants, SIAD has fitted a dedicated cylinder, equipped with a two-phase valve, which allows both the liquid and gaseous phase to be dispensed from the same package according to the operator's needs.
