R744 is a nomenclature used in industry to indicate carbon dioxide, a gas used predominantly as a liquid coolant in refrigeration systems, commercial and industrial.
The use of R744 as a refrigerant has been completely re-evaluated in recent decades because of environmental issues such as global warming and the toxicity of some components.
The advantages of the R744 are mainly in its low environmental impact: R744 it is not toxic, not flammable and contributes to reduced global warming.
Although not yet identified a replacement for the standard use of HFCs in refrigeration, the R744 is rapidly spreading in many countries, where some regulations encourage the use.
A major difficulty in using the R744 is given by the high pressure (up to 130 bar) and are therefore required components and systems capable of operating at high pressure systems, with high resistance.

Teklab, an italian manufacturer, is one of those companies that offer systems that can operate at high pressure. You can have a look at theirproducts for r744 refrigeration systems.
